If you have been churning out face masks and other PPE for coronavirus, like us, you’ve likely started to wonder if it’s possible to turn your 3D printer into an infinite 3D printer. Pulling parts off the print bed is tedious, time consuming, and requires being home when each job finishes. In this guide we teach you how to automatically eject parts from the print bed of your Ender 3 so you can start the next print while no one is around!
Disclaimer: Follow this tutorial at your own risk. Your printer is not built to do automatic part ejection. While we’ve discovered a technique that has been fairly reliable for us, it’s possible that if you don’t tweak the GCODE commands to your specifications, you can cause your printer to smash into things and do damage. Don’t blindly copy and paste GCODE commands, make sure you understand what they will cause the printer to do first.
