Robomatter’s Jacob Palnick, software engineer, and Angelo Callerame, 3D/2D artist, made a few upgrades to the 3D printer in our office recently using VEX Robotics parts! To get it started, they installed a Rasberry Pi with a program called Octoprint, along with attaching a webcam for recording and time lapse recordings, and an EDR limit switch as a filament detection sensor. Both of these items needed to be plugged in to the Octoprint to run correctly. When filament is feeding to the printer, the limit switch is pressed in, and then releases when there is no more filament to go to the printer. Once the switch releases, the print automatically stops.

Check out below how they set it up and some of the cool items they’ve printed so far:
