TRANSCRIPT
What is OctoPrint?● OctoPrint is a host software similar to
Printrun, Cura, Repetier Host or MakerWare.● The host software controls the 3D printer by
sending it the commands necessary to do it’s job.
How?● Host software is run on a computer that is
connected to the Arduino/microcontroller through a USB cable.
● Host software sends GCode files to the 3D printer, one line at at time.
Why?The ATmega328 chip found on the Uno:
Flash 32k bytes (of which .5k is used for the bootloader)SRAM 2k bytesEEPROM 1k byte
The ATmega2560 in the Mega2560 has larger memory space :
Flash 256k bytes (of which 8k is used for the bootloader)SRAM 8k bytesEEPROM 4k byte
Problem● Computer must be tethered to computer
throughout the job.● Inefficient. This is not computationally
intensive process. All it does is send a couple of text lines at a time.
Advantages● Using a Raspberry Pi, OctoPrint allows you
to untether your existing 3D printer from your laptop or workstation and turn it into a WiFi enabled one.
Installation❏ The software is completely free and open
source.❏ Go to octoprint.org and download OctoPi, an
SD card image that includes OctoPrint plus everything needed to run it.
❏ Flash the image to your SD card (detailed instructions are linked in the website).
Instructions❏ Connect WiFi dongle and make sure the
Raspberry Pi is connected to the local WiFi.❏ After booting up the Raspberry Pi, OctoPrint
should be available at http://octopi.local
