1. Product manual

Before you use the printer, please first finish the installation. Before the installation, pleasecarefully read through manuals of installation, manual leveling etc. After the installation, pleasecarefully read through the manuals again to check if the printer is correctly installed and correctlywired. If it is not correctly installed and wired, it may lead to machine malfunction.

Safety note:Hotbed and nozzle are high temperature parts, do not touch in case of getting burnt.Power supply part has potential danger, touching may lead to harm.

Attention:1. For the printer, please prevent contact with water and other liquid. Otherwise, it may lead tomachine damage.2. When loading the model, please do not turn off the power. Otherwise, it may lead to data loss ofmodel.3. During the printer debugging, there will be filament coming out of the nozzle. please make surethere is at least 50mm distance between the nozzle and the printing platform. Otherwise, it willlead to nozzle blockage.4. Normal working temperature of the printer is room temperature, and humidity 20% - 50%.Exceeding the range can affect forming quality. During the operation of the equipment, there maybe odor in the extrusion process due to material difference. Please keep the air well circulated. Ifyou feel discomfort, please stop using immediately and seek for corresponding treatment in thehospital.5. The SD card supports FAT32 file system. You can store G-Code into it for offline printing.6. One of the keys to successfully print a model lies in the printing platform. If you are using ABSmaterial, hotbed platform should be preheated to 90 degrees Celsius, keep the hotbed platformclean to increase adhesion. If you are using PLA material, you can apply glue (recommend UHUglue) to the hotbed platform, or preheat hotbed platform to 50 degrees Celsius.7. During the printing, temperature control of nozzle is also important. If you are using ABSmaterial, recommended temperature of nozzle is 220-240 degrees Celsius. If you are using PLAmaterial, recommended temperature of nozzle is 80-210 degrees Celsius. Please set up thetemperature according to material during actual printing.8. Please note the baud rate is 250000 when connecting the printer to the computer.9. When you print for the first time, first tighten the nozzle; when the temperature reaches 170degrees, tighten the nozzle again. In this way, blockage of nozzle will be unlikely. Also, changethe step per mm to 92 as below picture.

10. To make the forming quality better, please set up a reasonable printing speed. Higher printingspeed can reduce the printing time, but can result in poor forming quality; lower printing speedresults in longer printing time, but higher forming quality.11. After using the printer for a period of time, you need to check critical parts such as thesynchronous belt, push rod and screws if they are loosened.

Set as baud rate

39

Note: Communication ports and baud rate should be set up based on actual circumstance;Initial position should be set up as shown above; Printable radius and printable heightshould also be set up according to actual circumstance.

2. Script setup:

Select preview>Gcode edit>script

40

3. Balance adjustment:

Before balance adjustment, please make sure printer installation has finished andthe machine is under normal operation. When step 1 and step 2 are finished,please double check and make sure nothing has been left out and the printer canoperate normally. Then turn on power switch. PC and printer are properlyconnected , please prepare a piece of A4 paper. (If you have never done balanceadjustment before, we suggest you read through tutorial course on leveling beforeadjustment in case the machine were damaged by any faulty operation.)

A: Locate the lowest point

When the lowest point is located, please check the distance from nozzle to hotbedin case nozzle were damaged.

Send script 1 via shortcut key CTRL+ALT+1 to make printer nozzle drop to thelowest point of X axis. When the dropping process is finished, observe thedistance between nozzle and glass panel. Then send script 2 and script 3commands as well and observe the distance between nozzle and glass panel. (Asshown below) locate the lowest axis, (below we take X axis as example).

Lowest point of X axis

Lowest point of Y axis

41

B: Adjust the height of the lowest point

If X axis is the lowest one among X, Y and Z axis and there is some distancebetween the lowest point and the glass, then we can estimate the length of suchdistance (like 5mm or the nozzle touches the hotbed ) by visual inspection. Openup firmware and adjust values shown below (If the distance between nozzle andhotbed is about 274mm, you can set up as 274mm, but please note that this valueshouldn’t be too large). Re-burn the firmware to printer motherboard afteradjustment. When burning the firmware, please disconnect printer withRepetier-Host.

Lowest point of center areaLowest point of Z axis

42

After adjusting the value of Z axis above, re-connect printer with PC via Repetier-Host and put A4paper on the hotbed. Send script 1 command again via CTRL+ALT+1. If there is no contact betweennozzle and hotbed at this time, then repeat adjusting height of Z axis as above until the nozzle touchesthe glass; If nozzle has touched glass panel already, then pull the paper softly, if the paper stays still, liftup the nozzle by clicking Z axis per 0.1mm per step until A4 paper can be pulled with a certain amountof resistance force being felt. (Note: Resistance force here means the paper can be pulled by single handwith a certain amount of pressure being felt at the same time. If it is very hard to be pulled, it indicatesthat the resistance force is too strong. You can lift up nozzle height per 0.01mm per step until reachingabove state). Now, enter M114 in G-code and click send, the left-bottom corner of the screen willdisplay current coordinate value of nozzle, here we only need to know the height of Z axis, so notedown current coordinate value of Z axis and subtract that value from current value of

and (as shown by

below picture). Then disconnect printer with PC and burn the modified firmware to main control boardof printer. Re-connect printer with PC and send script 1 command via CTRL+ALT+1, now, if Z valuereaches zero, the nozzle should be able to generate some resistance force when the paper is pulled, if itdoes, it means adjustment on X axis is temporally finished.

Write down this value, value 274 in the firmware #define MANAUL_HOME_POS_274 minus this Z value

43

C. Height adjustment on the other two axes;

Let’s adjust the height of Y axis and Z0 point of Z axis. But the height of Y axis andZ axis should be adjusted by regulating balancing screw on the sliding block ratherthan by modifying firmware.

Send script command via CTRL+ALT+2 to make nozzle descend to the lowestpoint near Y axis. Observe the height between nozzle and glass (Since just now wetake the lowest axis as our subject for adjustment, now there is some distance between thenozzle and glass). Then we adjust the screw above the sliding block ofY axis, the nozzle is now away from glass and we need to revolve the screwanticlockwise. For example, if the distance between nozzle and glass is 2mm, we’llneed to revolve the screw anticlockwise for about 4 to 5 circles (the screw pitch is0.5mm, which means the screw will be lift up 0.5mm per circle), then send script 2command again and measure the distance between nozzle and glass by paper aswell. As for resistance force, you can refer to above statement. If the pressure is toobig, then turn the screw clockwise. Repeat above steps until reaching appropriaterange, which means the resistance force felt during pulling the paper is the samewith that of X axis. When adjustment on Y axis is finished, adjust Z axis in thesame way. Please note that if the deviation between the three axes is excessive, then afterinitial adjustment on the axes, the value of other two axes will change again.Please don’t worry if this happens, just re-adjust the not-okay axes by regulating the screwand repeat doing so until the height of drop point of these three axes is the same. Now,manual leveling on three points is close to finish.

Click arrow indicated area

44

D: Adjust geometrical radius of the machine;

When position adjustment on three axes is finished, we send scrip 4 command tomake nozzle move to the the middle of the glass. Similarly, we place a piece ofpaper underneath. If the paper is pressed down by nozzle and can’t be moved at all,

then decrease this value in file

, otherwise, increase this value. After saving firmware, makecorresponding update on main control board until A4 paper can be pulled with a certainamount resistance force being felt; Or if the paper can’t moved at all, you can change thevalue of Z (as pointed by red arrow in below picture) to a negative number (such as Z: -0.5)in firmware setup. After saving the changes, press CTRL+ALT+4 again until A4 can bepulled with a certain amount of resistance force being felt.

45

Now, press CTRL+ALT+1 again, if the nozzle near X axis point is so low that the paper is

pressed down, it means that this value in firmware

is too small and we need to increase it and update it to main control board. We don’t have to adjust this

value or the screw above the sliding block any more.

Repeat this step until A4 paper can be pulled with a certain amount of resistance force being felt. Nowthe whole manual leveling process is finished.

Conclusion: The ideal circumstance is that the distance between the nozzle and glass is always the samewhen script 1-4 commands are sent. That’s to say, when pulling the paper, you should feel a certainamount of resistance force. The distance should be equal to the thickness of a piece of A4 paper.

6. Height adjustment for 3D printer nozzle and hotbed

1. First, connect printer to you PC. After the connection, click “manual control” button on the right. You cansee interface as below picture. Then, enter M503 showed as red circled. Click send to check configuration ofthe printer.

47

2. Enter M503, you can see content“echo:M206 X0.00 Y0.00 Z0.00” circled in red line.

3. If during the test print, the height between the nozzle and the hotbed is 0.5mm, we enter M206 X0.5 in thered circled box and click send. During the adjustment, the value should increase little by little to avoid nozzlepressing hotbed due to high value and damaging the nozzle.

48

4. After entering M206 X0.5 and click send, we should save the adjusted parameter. Enter M500 in the redcircled box; click send and modification will be saved.

5. After saving the modified value, let’s reenter M503 and click send. See if the red circled value has beenchanged to 0.5. If so, the modification is succeeded. If in this value, there is still height between the nozzleand the hotbed. Please adjust by repeating step 1-4.

49

6. If the value gets bigger and bigger according to the above method and there is still height between thenozzle and the hotbed, please check the line #define MANUAL_Z_HOME_POS 273mm in firmware fileConfiguration.h as shown in below picture. First, use a ruler to measure the height between nozzle andhotbed when nozzle is at its highest position. If the height is more than 273mm, change the value here to theactual measured value. For example, if the actual measured height is 274mm, change the code into: #defineMANUAL_Z_HOME_POS 274.

Of course, there is another way to do this without changing the firmware parameters. See below picture; adda screw to the arrow indicated area; and if one axis adds a screw, other two axes need screws too. Forexample, if the the height between the nozzle and the hotbed is 1MM, the distance between the screw and themicroswitch is 1MM. After the adjustment, do the test print to see if it works.

7. Easy use of Repetier-Host software

(Examples base on version Repetier-Host 1.06)

1. Repetier-Host overview

Repetier Host is an easy to use software for 3D printing. The main functions include manual debugging

50

and model slicing. Repetier Host is one of the most widely used printing software for 3D printing. Below isan interface picture of successful installation of Repetier - Host 1.06.

56

2） Control the motor rotation through the display.In standby mode interface, click the knob button to enter the next level menu. Click Prepare Move axisMove 0.1mm Move X、Move Y、Move Z or Move E

For X axis, it moves to the right with increase of value; for Y axis, it moves backwards with increase ofvalue; for Z axis, it moves upwards with increase of value; for E axis,it rotates forward(feeding) withincrease of value.Above directions are true when you directly face your display.After the above, we use G28 to home the machine and check if everything is working correctly.

4). for height adjustment of 3D printing nozzle and hotbed, please refer to another file.

2. slicing

1）parameter setup for Slic3r

Please save each setup.A. Print Settings

1). layers and perimeters

57

A. In layer setting, there are layer height and first layer height. Layer height means height for each layerduring the printing. It’s generally based on nozzle diameter. The higher the value, the coarser the product.The lower the value, the finer.The height of the first layer will be lower than the other layers because first layer will be pressed down and iftoo high, material will pile up, not good for other layer printing.B. Then it’s the perimeters. Perimeter means the minimum thickness of the outer layer, normally no less than3.C. Horizontal shells means layers on the top and bottom, often with solid layer. You can define the top andbottom layer here.D. For advanced, just use the default ones.

2). infill settings

58

A. In the infill settings. One option is fill density, which means density of filament. For fill pattern andtop/bottom fill pattern, you can choose freely as they don’t affect product much.B. For advanced, just use the default ones.

3). speed setup

59

Special attention: in the first printing, you need to set all speeds at 20mm/s. When the first printing is asuccess, you can try to set the speed higher but in reasonable values.

For speed setup, there are many items, but all very clear. Among them, speed for non-print moves meansmoving without load. Note that for first layer speed, don’t set too high or filament cannot stick to hotbed.

4). skirt and brim setup

This setup is for the nozzle action in the beginning. It will be a circle of lines around the product. We suggestyou keep this setup because in the beginning, the nozzle will be in short of filament. After one circle, thefilament feeding will be normal.

5). support material setup

60

During the printing, there may be hollow parts or connection using bridge. If the bridge is too long, supportis needed. Support is extra part, you can remove after the the printing is complete. Raft is the base layerduring the printing. When printing on glass hotbed, raft is not recommended.

6). notes

You can add things you want to write down, just like a notebook.

61

7). Output options setup

This option includes sequential printing and output file etc. Just use the default ones.8). extruder setup

This option is for multiple extruders. Not needed for 1 extruder.

62

9). advanced

Suggest not to change any parameters in this option.

3). Extruder setup

For extruder setup, because we only need one extruder. That means we only need to have one setup.Size: According to actual situation. For Pri3, nozzle diameter is 0.4mm.Position: stop position when printing is complete. You can set up freely but do not exceed the printing area.Retraction: after printing out 1 filament, the extruder will have a retraction. You can set up here though wesuggest we go with the defaults.Advanced is for multiple extruders, you don’t need to set up for 1 extruder.

C. filament setting1). filament setup

65

Filament setup: diameter according to actual diameter, usually are 3mm and 1.75mm. Temperature setup: this setting is important. There are two kinds of materials. One is ABS; another one is

PLA. For ABS, temperature settings are: extruder 220℃, hotbed 110℃; for PLA: extruder 185℃,hotbed 55℃.

2). cooling setup

66

For cooling option, it’s mainly used in printing small objects or printing hole parts. Otherwise, warpage willhappen in printing big objects.

2）CuraEngine Settings

Open Repetier-Host software; click slicing software; select CuraEngine as red circle shows.

Click configuration, you can see CuraEnginesetup interface as below.

67

1). printing setupA. Speed and quality

For the first time printing, please refer to below setup. After the setup, click “save as” and enter a name in theprompt box to save as your own configuration. For the first layer, extrusion width can set up as 200% toincrease bonding between the printing object and the hotbed to avoid warpage.

68

B. structureFor the first time printing, set up as below picture. For different object, set up different parameters for betterresult.

69

C. extrusionSet up as below picture. If there is only one extruder, no need to set up multiple extruder option. If you areprinting spiral object, you need to select option “spiral perimeter”.

For ABS, temperature settings are: extruder 220℃, hotbed 100℃; for PLA: extruder 185℃, hotbed 55℃.

72

8. G-code

This page tries to describe the flavour of G-codes that the RepRap firmwares use and how they

work. The main target is additive fabrication using FFF/FDM processes (3D printing). Codes for

print head movements follow the NIST RS274NGC G-code standard, so RepRap firmwares are

quite usable for CNC milling and similar applications

As many different firmwares exist and their developers tend to implement new features without

discussing strategies or looking what others did before them, a lot of different sub-flavours for the

3D-Printer specific codes developed over the years.

8 Alternatives to G-code

Introduction

A typical piece of Gcode as sent to a RepRap machine might look like this:

N3 T0*57

N4 G92 E0*67

N5 G28*22

N6 G1 F1500.0*82

N7 G1 X2.0 Y2.0 F3000.0*85

N8 G1 X3.0 Y3.0*33

The meaning of all those symbols and numbers (and more) is explained below.

Below table clearly shows which specific Gcode(s) are implemented in any given firmware; some

are still experimental.

Support

FiveD Teacup Sprinter Marlin Repetier

yes automatic yes yes experimental

Here means:

Yes:

The Gcode is fully supported by the firmware.

Experimental:

There is some support for the Gcode. Often it is required to check out the source code

branch for the firmware; may also require some modification.Automatic:

The firmware handles this Gcode automatically, so there's no need to send the command.

An example is power supply on/off Gcode (M80/M81) in the Teacup firmware.No:

The firmware does not support this Gcode.




78

For the technically minded, Gcode line endings are Unix Line Endings (\n), but will accept

Windows Line Endings (\r\n), so you should not need to worry about converting between the two.

RepRap G-code fields

This section explains the letter-preceded fields. The numbers in the fields are represented by nnn.

Numbers can be integers, or can contain a decimal point, depending on context. For example an X

coordinate can be integer (X175) or fractional (X17.62), whereas trying to select extruder number

2.76 would make no sense.）

Letter Meaning

Gnnn Standard GCode command, such as move to a point

Mnnn RepRap-defined command, such as turn on a cooling fan

Tnnn Select tool nnn. In RepRap, tools are extruders

Snnn Command parameter, such as time in seconds; temperatures; voltage to send to a motor

Pnnn Command parameter, such as time in milliseconds; proportional (Kp) in PID Tuning

Xnnn A X coordinate, usually to move to. This can be an Integer or Fractional number.

Ynnn A Y coordinate, usually to move to. This can be an Integer or Fractional number.

Znnn A Z coordinate, usually to move to. This can be an Integer or Fractional number.

Innn Parameter - X-offset in arc move; integral (Ki) in PID Tuning

Jnnn Parameter - Y-offset in arc move

Fnnn Feedrate in mm per minute. (Speed of print head movement)

Rnnn Parameter - used for temperatures

Qnnn Parameter - not currently used

Ennn

Length of extrudate. This is exactly like X, Y and Z, but for the length of filament to

extrude. It is common for newer stepper based systems to interpret ... Better: Skeinforge

40 and up interprets this as the absolute length of input filament to consume, rather than

the length of the extruded output.

Nnnn Line number. Used to request repeat transmission in the case of communications errors.

*nnn Checksum. Used to check for communications errors.

79

Comments

G Code comments:

N3 T0*57 ; This is a comment

N4 G92 E0*67

; So is this

N5 G28*22

Comments and white space will be ignored by your RepRap Printer. It's better to strip these out on

the host computer before sending the Gcode to your printer, as this saves bandwidth.

Individual commands

Checking codes

N and *

Example: N123 [...G Code here...] *71

These are line number and tagged number. RepRap firmware will compare the tagged number

with a locally-computed value and, if they differ, requests a repeat transmission of the line of the

given number.

Although RepRap can still work without line number and checking number, it will not do the

checking. You may use both or omitting both.

Checksum cs is to use Gcode cmd (including line number) to have bit exclusive-or operation.

Below is example code:

int cs = 0;

for(i = 0; cmd[i] != '*' && cmd[i] != NULL; i++)

cs = cs ^ cmd[i];

cs &= 0xff; // Defensive programming...

The cs value is the decimal digit on the right of *.

The RepRap firmware expects line numbers to increase by 1 each line, and if that doesn't happen

it is flagged as an error. But you can reset the count using M110 (see below).

Note: the purpose for line number and checksum is to reduce signal interference.

80

Delay G-commands

If buffering is supported, the RepRap firmware stores some commands in a ring buffer internally

for execution. This means that there is no (appreciable) delay while a command is acknowledged

and the next transmitted. In turn, this means that sequences of line segments can be plotted

without a dwell between one and the next. As soon as one of these buffered commands is received

it is acknowledged and stored locally. If the local buffer is full, then the acknowledgment is

delayed until space for storage in the buffer is available. This is how flow control is achieved.

G0: Rapid move

Example: G0 X12

It will move X = 12 mm for this command. In fact, for RepRap, the efficiency of this command is

the same with G1 X12. ( this command is for old machines that prefer moving in folding line to go

linear. That’s why it’s called rapid move)

G1: Controlled move

Example: G1 X90.6 Y13.8 E22.4

From the current position (X, Y) moves to the designated position (90.6, 13.8) while extruding

22.4mm of filament between the two points. (note: the extrusion is controlled by E22.4command)

RepRap is very sensitive to the feedrate, so we first set the feedrate to 1500mm/minute, then move

to (X90.6 Y13.8) and do the the extrusion.

G1 F1500

G1 X90.6 Y13.8 E22.4

SupportFiveD Teacup Sprinter Marlin Repetier

??? yes yes yes yes


yes yes yes yes yes

81

But for the code below, we set a feedrate of 1500 mm/minute first, then do the move described

above accelerating to a feedrate of 3000 mm/minute as it does so.

G1 F1500

G1 X90.6 Y13.8 E22.4 F3000

To reverse the extruder by a given amount (for example to reduce its internal pressure while it

does an in-air movement so that it doesn't dribble) simply use G0 or G1 to send an E value that is

less than the currently extruded length.

Note: not all firmware supports this function (change feedrate during movement). For

example, Marlin will use the new feedrate at the very beginning and will not change during the

movement.

For the first example, it keeps fixed feedrate during movement; for the second one, it changes the

feedrate during the movement, so for below code, the feedrate will first be accelerated to 3000

mm/minute and then reduce to1500 mm/minute.

G1 F1500

G1 X90.6 Y13.8 E22.4 F3000

G1 X80 Y20 E36 F1500

For the filament retraction, we can reverse the extruder motor to reduce its internal pressure while

it does an in-air movement so that it doesn't dribble, which can greatly reduce burr defect during

the printing. Specific operation: send G1 Ennn command to RepRap, in which the nnn should be

lower than the current value.

G28: Move to Origin

Example: G28

When the RepRap firmware receives this command, it moves all (or the supplied) axis's back to

the zero endstops as quickly as it can, then backs off by a millimeter and slowly moves back to the

zero endstop activation points to increase position accuracy.


yes yes yes yes yes

http://reprap.org/wiki/Marlin

82

If you add coordinates, only coordinates added will be homed. For example “G28 X0 Y72.3”,

only X and Y axis will be homed, no homing for the Z axis (numbers after X and Y will be

ignored).

G29-G32: Bed probing

G29 Detailed Z-Probe

probes the bed at 3 points.

G30 Single Z Probe

probes bed at current XY location.

G31 Report Current Probe status

reports whether Z probe is triggered. G32 Probe Z and calibrate with FPU

probes the bed at 3 points and updates transformation matrix for bed leveling

compensation.

Immediate G command

The below commands will be buffered and be responded only after all the previous buffered

commands are executed. So the main machine will wait until all commands are executed (latest

respond). These temporary stops will not affect the normal function of the machine.

Teacup Firmware buffers G20, G21, G90 and G91.

G4: Dwell

Example: G4 P200

In this case sit still doing nothing for 200 milliseconds. During delays the state of the machine (for

example the temperatures of its extruders) will still be preserved and controlled.

G10: tool offset

Example: G10 P3 X17.8 Y-19.3 Z0.0 R140 S205

This sets the offset for tool (or in older implementations extrude head) 3 (from the P3) to the X

and Y values specified. You can put a non-zero Z value in as well, but this is usually a bad idea

unless the tools are loaded and unloaded by some sort of tool changer. When all the tools are in

the machine at once they should all be set to the same Z height.

Remember that any parameter that you don't specify will automatically be set to the last value for

that parameter. That usually means that you want explicitly to set Z0.0.

http://reprap.org/wiki/Teacup_Firmware

83

The R value is the standby temperature in oC that will be used for the tool, and the S value is its

operating temperature. If you don't want the tool to be at a different temperature when not in use,

set both values the same. See the T code (select tool) .

The NIST G-code standard mentions an additional L parameter, which is ignored.

This command is subject to discussion.

G20: Set Units to Inches

Example: G20Units from now on are in inches.

G21: Set Units to Millimeters

Example: G21Units from now on are in millimeters. (This is the RepRap default.)

G90: Set to Absolute Positioning

Example: G90

All coordinates from now on are absolute relative to the origin of the machine. (This is the

RepRap default.)

G91: Set to Relative Positioning

Example: G91

All coordinates from now on are relative to the last position

G92: Set Position

Example: G92 X10 E90

Allows programming of absolute zero point, by resetting the current position to the values

specified. This would set the machine's X coordinate to 10, and the extrude coordinate to 90. No

physical motion will occur.

A G92 without coordinates will reset all axes to zero.

Immediate M and T commands

M0: Stop

Example: M0

The RepRap machine finishes any moves left in its buffer, then shuts down. All motors and

heaters are turned off. It can be started again by pressing the reset button on the master

microcontroller. See also M1, M112.M1: Sleep

Example: M1

http://www.nist.gov/customcf/get_pdf.cfm?pub_id=823374

http://reprap.org/wiki/Talk:G-code

84

The RepRap machine finishes any moves left in its buffer, then shuts down. All motors and

heaters are turned off. It can still be sent G and M codes, the first of which will wake it up again.

- Is this not the same as M84? -- MrAlvin 05:53, 20 September 2012 (UTC)M20: List SD card

Example: M20

All files in the root folder of the SD card are listed to the serial port. One name per line, like:

ok Files: {SQUARE.G,SQCOM.G,}


http://reprap.org/wiki/User:MrAlvin

85

‘, ’ mark is optional . Note that some firmwares list file names in upper case, but - when sent to

the M23 command (below) they must be in lower case. This seems to be a function of the SD

software. Go figure...M21: Initialize SD card

Example: M21The SD card is initialized. If an SD card is loaded when the machine is switched on, this will

happen by default. SD card must be initialized for the other SD functions to work.

M22: Release SD card

Example: M22

SD card is released, so further (accidental) attempts to read from it are guaranteed to fail. Helpful,

but not mandatory before removing the card physically.M23: Select SD file

Example: M23 filename.gcoThe file specified as filename.gco (8.3 naming convention is supported) is selected ready for

printing.

M24: Start/resume SD print

Example: M24

The machine prints from the file selected with the M23 command.M25: Pause SD print

Example: M25

The machine pauses printing file selected with the M23 command at the current position.M26: Set SD position

Example: M26

Set SD position in bytes (M26 S12345).M27: Report SD print status

Example: M27

Report SD print status.M28: Begin write to SD card

Example: M28 filename.gco

File specified by filename.gco is created (or overwritten if it exists) on the SD card and all

subsequent commands sent to the machine are written to that file.M29: Stop writing to SD card


File opened by M28 command is closed, and all subsequent commands sent to the machine are

executed as normal.M30: Delete a file on the SD card


filename.gco is deleted.

86

M40: Eject

If your RepRap machine can eject the parts it has built off the bed, this command executes the

eject cycle. This usually involves cooling the bed and then performing a sequence of movements

that remove the printed parts from it. The X, Y and Z position of the machine at the end of this

cycle are undefined (though they can be found out using the M114 command, q.v.).

See also M240 and M241 below.M41: Loop

Example: M41

If the RepRap machine was building a file from its own memory such as a local SD card (as

opposed to a file being transmitted to it from a host computer) this goes back to the beginning of

the file and runs it again. So, for example, if your RepRap is capable of ejecting parts from its

build bed then you can set it printing in a loop and it will run and run. Use with caution - the only

things that will stop it are:

1. When you press the reset button,

2. When the build material runs out (if your RepRap is set up to detect this), and

3. When there's an error (such as a heater failure).M42: Stop on material exhausted / Switch I/O pin

M42 in ???

Example: M42

If your RepRap can detect when its material runs out, this decides the behaviour when that

happens. The X and Y axes are zeroed (but not Z), and then the machine shuts all motors and

heaters off. You have to press reset to reactivate the machine. In other words, it parks itself and

then executes an M0 command (q.v.).M42 in Marlin/Sprinter

Example: M42 P7 S255

M42 switches a general purpose I/O pin.M42 in Teacup

Not needed. General purpose devices are handled like a heater, see M104.M43: Stand by on material exhausted

Example: M43

If your RepRap can detect when its material runs out, this decides the behaviour when that

happens. The X and Y axes are zeroed (but not Z), and then the machine shuts all motors and

heaters off except the heated bed, the temperature of which is maintained. The machine will still

respond to G and M code commands in this state.M80: ATX Power On

Example: M80

Turns on the ATX power supply from standby mode to fully operational mode. No-op on

electronics without standby mode.


87

Note: some firmwares, like Teacup, handle power on/off automatically, so this is redundant there.M81: ATX Power Off

Example: M81Turns off the ATX power supply. Counterpart to M80.

M82: Set extruder to absolute mode

Example: M82

makes the extruder interpret extrusion as absolute positions.This is the default in repetier.

M83: Set extruder to relative mode

Example: M83

makes the extruder interpret extrusion values as relative positions.M84: Stop idle hold

Example: M84

Stop the idle hold on all axis and extruder. In some cases the idle hold causes annoying noises,

which can be stopped by disabling the hold. Be aware that by disabling idle hold during printing,

you will get quality issues. This is recommended only in between or after printjobs.M92: set axis_steps_per_unit

Example: M92 X<newsteps> Sprinter and MarlinAllows programming of steps per unit of axis till the electronics are reset for the specified axis.

Very useful for calibration.

M98: get axis_hysteresis_mm

Example: M98

Report current hysteresis value of XYZ axis.Proposed for Marlin

M99: set axis_hysteresis_mm

Example: M99 X<mm> Y<mm> Z<mm> E<mm>

Mechanical pulleys, gears and threads can have hysteresis when they change direction. That is, a

certain number of steps occur before movement occurs. You can measure how many mm are lost

to hysteresis and set their values with this command. Every time an axis changes direction, these

extra mm will be added to compensate for the hysteresis.Proposed for Marlin

M101 Turn extruder 1 on (Forward), Undo Retraction

M101 in Teacup firmware

If a DC extruder is present, turn that on. Else, undo filament retraction, which means, make the

extruder ready for extrusion. Complement to M103.M101 in other firmwares

Deprecated. Regarding filament retraction, see M227, M228, M229.M102 Turn extruder 1 on (Reverse)

http://reprap.org/wiki/Teacup_Firmware

Deprecated.M103 Turn all extruders off, Extruder Retraction

M103 in Teacup firmware

If a DC extruder is present, turn that off. Else, retract the filament in the hope to prevent nozzle

drooling. Complement to M101.M103 in other firmwares

Deprecated. Regarding extruder retraction, see M227, M228, M229.M104:Set Extruder Temperature

Example: M104 S190

Set the temperature of the current extruder to 190oC and return control to the host (PC)

immediately (i.e. before that temperature has been reached by the extruder). See also M109.

This is deprecated because temperatures should be set using the G10 and T commands (q.v.).

Deprecation is subject to discussion. --Traumflug 11:33, 19 July 2012 (UTC)M104 in Teacup Firmware

In Teacup Firmware, M104 can be additionally used to handle all devices using a temperature

sensor. It supports the additional P parameter, which is a zero-based index into the list of sensors

in config.h. For devices without a temp sensor, see M106.


Set the temperature of the device attached to the second temperature sensor to 100 °C.M105: Get Extruder Temperature

Example: M105

Request the temperature of the current extruder and the build base in degrees Celsius. The

temperatures are returned to the host computer. For example, the line sent to the host in response

to this command looks like: ok T:201 B:117

M106: fan on

Example: M106 S127

Turn on the cooling fan at half speed.

'Mandatory parameter 'S' declares the PWM value (0-255). M106 S0 turns the fan off.M106 in Teacup Firmware


yes yes yes yes yes


yes yes yes


http://reprap.org/wiki/User:Traumflug


89

Additionally to the above, Teacup Firmware uses M106 to control general devices. It supports the

additional P parameter, which is an zero-based index into the list of heaters/devices in config.h.


Turn on device #3 at full speed/wattage.

Note: When turning on a temperature sensor equipped heater with M106 and M104 at the same

time, temperature control will override the value given in M106 quickly.M107: Fan Off

Deprecated in Teacup firmware. Use M106 S0 instead..M108: Set Extruder Speed

Sets speed of extruder motor. (Deprecated in FiveD firmware, see M113)

M109: Set Extruder Temperature and Wait

M109 in Teacup

Not needed. To mimic Marlin behaviour, use M104 followed by M116.M109 in Marlin, Sprinter (ATmega port)

Set Extruder Temperature and Wait

Example: M109 S185M109 in Sprinter (4pi port)

Parameters: S (optional), set target temperature value. If not specified, waits for the temperature

set by M104. R (optional), sets target temperature range maximum value.

Example: M109 S185 R240 //sets extruder temperature to 185 and waits for the temperature to be

between 185 - 240.

If you have multiple extruders, use T or P parameter to specify which extruder you want to

set/wait.

Another way to do this is to use G10.M110: Set Current Line Number

Example: M110 N123

Set the current line number to 123. Thus the expected next line after this command will be 124.


??? not needed see text yes ???


??? not needed ??? ??? ???





90

M111: Set Debug Level

Example: M111 S6

Set the level of debugging information transmitted back to the host to level 6. The level is the OR

of three bits:

#define DEBUG_ECHO (1<<0)

#define DEBUG_INFO (1<<1)

#define DEBUG_ERRORS (1<<2)

Thus 6 means send information and errors, but don't echo commands. (This is the RepRap

default.)

Example: M253M112: Emergency

Stop

Example: M112Any moves in progress are immediately terminated, then RepRap shuts down. All motors and

heaters are turned off. It can be started again by pressing the reset button on the master

microcontroller. See also M0 and M1.

M113: Set Extruder PWM

Example: M113

Set the PWM for the currently-selected extruder. On its own this command sets RepRap to use the

on-board potentiometer on the extruder controller board to set the PWM for the currently-selected

extruder's stepper power. With an S field:

M113 S0.7

it causes the PWM to be set to the S value (70% in this instance). M113 S0 turns the extruder off,

until an M113 command other than M113 S0 is sent.M114: Get Current Position

Example: M114

This causes the RepRap machine to report its current X, Y, Z and E coordinates to the host.

For example, the machine returns a string such as:

ok C: X:0.00 Y:0.00 Z:0.00 E:0.00M115: Get Firmware Version and Capabilities

Example: M115

Request the Firmware Version and Capabilities of the current microcontroller The details are

returned to the host computer as key:value pairs separated by spaces and terminated with a

linefeed.

sample data from firmware:


Debug

91

ok PROTOCOL_VERSION:0.1 FIRMWARE_NAME:FiveD

FIRMWARE_URL:http%3A//reprap.org MACHINE_TYPE:Mendel EXTRUDER_COUNT:1

This M115 code is inconsistently implemented, and should not be relied upon to exist, or output

correctly in all cases. An initial implementation was committed to svn for the FiveD Reprap

firmware on 11 Oct 2010. Work to more formally define protocol versions is currently (October

2010) being discussed. See M115_Keywords for one draft set of keywords and their meanings.M116: Wait

Example: M116

Wait for all temperatures and other slowly-changing variables to arrive at their set values. See also

M109.M117: Get Zero Position

Example: M117

This causes the RepRap machine to report the X, Y, Z and E coordinates in steps not mm to the

host that it found when it last hit the zero stops for those axes. That is to say, when you zero X,

the x coordinate of the machine when it hits the X endstop is recorded. This value should be 0, of

course. But if the machine has drifted (for example by dropping steps) then it won't be. This

command allows you to measure and to diagnose such problems. (E is included for completeness.

It doesn't normally have an endstop.)M117 in Marlin: Display Message

Example: M117 Hello WorldThis causes the given message to be shown in the status line on an attached LCD. The above

command will display Hello World.

M118: Negotiate Features

Example: M118 P42

This M-code is for future proofing. NO firmware or hostware supports this at the moment. It is

used in conjunction with M115's FEATURES keyword.

See Protocol_Feature_Negotiation for more info.M119: Get Endstop Status

Example: M119

Returns the current state of

the configured X, Y, Z endstops. Takes into account any 'inverted endstop' settings, so one can

confirm that the machine is interpreting the endstops correctly.M120: Push


yes yes

http://reprap.org/wiki/M115_Keywords

http://reprap.org/wiki/Protocol_Feature_Negotiation

92

Push the state of the RepRap machine onto a stack. Exactly what variables get pushed depends on

the implementation (as does the depth of the stack - a typical depth might be 5). A sensible

minimum, however, might be

1. Current feedrate, and

2. Whether moves (and separately extrusion) are relative or absoluteM121: Pop

Recover the last state pushed onto the stack.M126: Open Valve

Example: M126 P500

Open the extruder's valve (if it has one) and wait 500 milliseconds for it to do so.M127: Close Valve

Example: M127 P400

Close the extruder's valve (if it has one) and wait 400 milliseconds for it to do so.M128: Extruder Pressure PWM

Example: M128 S255

PWM value to control internal extruder pressure. S255 is full pressure.M129: Extruder pressure off

Example: M129 P100

In addition to setting Extruder pressure to 0, you can turn the pressure off entirely. P400 will wait

100ms to do so.M130: Set PID P value

Example: M130 P 0 S 8.0 # Sets heater 0 P factor to 8.0

M131: Set PID I value

Example: M130 P 1 S 0.5 # Sets heater 1 I factor to 0.5

M140: Bed Temperature (Fast)

Example: M140 S55

Set the temperature of the build

bed to 55oC and return control to

the host immediately (i.e. before

that temperature has been reached by the bed).M141: Chamber Temperature (Fast)

Example: M141 S30

Set the temperature of the chamber to 30oC and return control to the host immediately (i.e. before

that temperature has been reached by the chamber).M142: Holding Pressure

Example: M142 S1

Set the holding pressure of the bed to 1 bar.

The holding pressure is in bar. For hardware which only has on/off holding, when the holding

pressure is zero, turn off holding, when the holding pressure is greater than zero, turn on holding.M143: Maximum hot-end temperature

Example: M143 S275Set the maximum temperature of the hot-end to 275C


yes


yes


Debug


yes yes yes yes

94

When temperature of the hot-end exceeds this value, take countermeasures, for instance an

emergency stop. This is to prevent hot-end damage.

M160: Number of mixed materials

Example: M160 S4

Set the number of materials, N, that the current extruder can handle to the number specified. The

default is 1.

When N >= 2, then the E field that controls extrusion requires N+1 values separated by spaces

after it like this:

M160 S4

G1 X90.6 Y13.8 E22.4 0.1 0.1 0.1 0.7

G1 X70.6 E42.4 0.0 0.0 0.0 1.0

G1 E42.4 1.0 0.0 0.0 0.0

The second line moves straight to the point (90.6, 13.8) extruding 22.4mm of filament. The mix

ratio at the end of the move is 0.1:0.1:0.1:0.7.

The third line moves back 20mm in X extruding 20mm of filament. The mix varies linearly from

0.1:0.1:0.1:0.7 to 0:0:0:1 as the move is made.

The fourth line has no physical effect, but sets the mix proportions for the start of the next move to

1:0:0:0.M190: Wait for bed temperature to reach target temp

Example: M190 S60

This will wait until the bed

temperature reaches 60 degrees, printing out the temperature of the hot end and the bed every

second.

Example: M206 X10.0 Y10.0 Z-0.4

The values specified are added to the endstop position when the axes are referenced. The same can

be achieved with a G92 right after homing (G28, G161).

With Marlin firmware, this value can be saved to EEPROM using the M500 command.

A similar command is G10, aligning these two is subject to discussion.M207: Calibrate z axis by detecting z max length

Example: M207

After placing the tip of the nozzle in the position you expect to be considered Z=0, issue this

command to calibrate the Z axis. It will perform a z axis homing routine and calculate the distance

traveled in this process. The result is stored in EEPROM as z_max_length. For using this

calibration method the machine must be using a Z MAX endstop.

This procedure is usually more reliable than mechanical adjustments of a Z MIN endstop.M208: Set axis max travel

Example: M208 X250 Y210 Z180

With Marlin firmware, this value can be saved to EEPROM using the M500 command.

The values specified set the software limits for axis travel in the positive direction.

With Marlin firmware, this value can be saved to EEPROM using the M500 command.M209: Enable automatic retract（Retraction）

Example: M209 S1

This boolean value S 1=true or 0=false enables automatic retract detect if the slicer did not support

G10/11: every normal extrude-only move will be classified as retract depending on the direction.M220:set speed factor override percentage

M226: Gcode Initiated Pause

Example: M226

Initiates a pause in the same way as if the pause button is pressed. That is, program execution is

stopped and the printer waits for user interaction. This matches the behaviour of M1 in the NIST

RS274NGC G-code standard and M0 in Marlin firmware.M227: Enable Automatic Reverse and Prime


P and S are steps.

"Reverse and Prime" means, the extruder filament is retracted some distance when not in use and

pushed forward the same amount before going into use again. This shall help to prevent drooling

of the extruder nozzle. Teacup firmware implements this with M101/M103.M228: Disable Automatic Reverse and Prime

Example: M228

See also M227.M229: Enable Automatic Reverse and Prime

Example: M229 P1.0 S1.0

Usage: M420 R<Red PWM (0-255)> E<Green PWM (0-255)> B<Blue PWM (0-255)>

Example: M420 R255 E255 B255

Set the color of your RGB LEDs that are connected to PWM-enabled pins. Note, the Green color

is controlled by the E value instead of the G value due to the G code being a primary code that

cannot be overridden.T: select tool

Example: T1

Select tool (or in older implementations extruder) number 1.

The sequence followed is:

1. Set the current extruder to its standby temperature specified by G10 (see above),

2. Set the new extruder to its operating temperature specified by G10 and wait

for all temperatures to stabilise,

3. Apply any X, Y, Z offset for the new extruder specified by G10,

4. Use the new extruder.

Selecting a non-existent tool (100, say) just does Step 1. above. That is to say it leaves all tools in

their standby state. You can, of course, use the G10 command beforehand to set that standby

temperature to anything you like.

Note that you may wish to move to a parking position before executing a T command in order to

allow the new extruder to reach temperature while not in contact with the print. It is acceptable for

the firmware to apply a small offset [by convention (-1mm x tool-number) in Y] to the current

position when the above sequence is entered to allow temperature changes to take effect just away

from the parking position. Any such offset must, of course, be undone when the procedure

finishes.

If the Z value changes in the offsets and the head moves up, then the Z move is made before the X

and Y moves. If Z moves down, X and Y are done first.

After a reset extruders will not start heating until they are selected. You can either put them all at

their standby temperature by selecting them in turn, or leave them off so they only come on

if/when you first use them. The M0, M1 and M112 commands turn them all off. You can, of

course, turn them all off with the M1 command, then turn some back on again. Don't forget also to

turn on the heated bed (if any) if you use that trick.

Extruder numbering starts at 0.

Proposed EEPROM configuration codes

99

BRIEFLY: each RepRap has a number of physical parameters that should be persistent, but easily

configurable, such as extrusion steps/mm, various max values, etc. Those parameters are currently

hardcoded in the firmware, so that a user has to modify, recompile and re-flash the firmware for

any adjustments. These configs can be stored in MCU's EEPROM and modified via some

M-codes. Please see the detailed proposal at M-codes for EEPROM config. (This is proposed by

--AlexRa on 11-March-2011. There is currently no working implementation of the proposed

commands).

Marlin uses these codes to manipulate EEPROM values.

Sprinter has implemented the following commands to manipulate EEPROM Commit message.

Teacup uses codes M130-M136 to set, read, and save some parameters.M500: Store parameters in EEPROM

M501: Read parameters from EEPROM

If you need to reset them after you changed them temporarilyM502: Revert to the default "factory settings."

It must be followed with M501to store this setting.M503: Print settings

Replies from the RepRap machine to the host computer

All communication is in printable ASCII characters. Messages sent back to the host computer are

terminated by a newline and look like this:

xx [line number to resend] [T:93.2 B:22.9] [C: X:9.2 Y:125.4 Z:3.7 E:1902.5] [Some

debugging or other information may be here]

xx can be one of:

ok

rs

!!

ok means that no error has been detected.

rs means resend, and is followed by the line number to resend.

!! means that a hardware fault has been detected. The RepRap machine will shut down

immediately after it has sent this message.

The T: and B: values are the temperature of the currently-selected extruder and the bed

respectively, and are only sent in response to M105. If such temperatures don't exist (for example

for an extruder that works at room temperature and doesn't have a sensor) then a value below

absolute zero (-273oC) is returned.

C: means that coordinates follow. Those are the X: Y: etc values. These are only sent in response

to M114 and M117.

The RepRap machine may also send lines that look like this:

// This is some debugging or other information on a line on its own. It may be sent at any

time.

Such lines will always be preceded by //.

The most common response is simply:

ok

When the machine boots up it sends the string

start

once to the host before sending anything else. This should not be replaced or augmented by

version numbers and the like. M115 (see above) requests those.

All this means that every line sent by RepRap to the host computer except the start line has a

two-character prefix (one of ok, rs, !! or //). The machine should never send a line without such a

prefix.

Exceptions: Marlin 1.0.0 Gen6 Firmware does not follow the two character rule. 'rs' is actually

'Resend' and '!!' is 'Error'. Example Lines:

Error: Line Number is not current line + 1. Last Line: 7

Resend: 8

When in the code base did this change take place and what other firmwares are affected?

Proposal for sending multiple lines of G-code

So far, this is a proposal, open for discussion.Problem to solve

Each line of G-code sent from the host to the controller is answered with an ok before the next

line can be sent without locking communcations up. This makes operations very slow, as the usual

USB-TTL converters and probably also the host's operating system drivers come with substantial

latency, often 10 milliseconds.

Elegant multispline motion controller "will not use G-code. It will use a custom language

based on cubic Bezier curves. This allows for much better description of arcs and will result in

much higher quality prints with a much lower data throughput requirements."Category:
