this is a robot i made that automatically swaps the build plate of my 3d printer. it extends with timing belts driven by 2 stepper motors, sucks the plate with 4 electromagnets, and turns with a pulley on the bottom. the video's sped up 4x, a cycle takes ~70 sec because the steppers skip if i try to go faster. this is because the magnet on the printer bed is insanely strong lol currently it uses a button at the bottom to trigger it to change the build plate, but i think wireless would be better. thinking of setting up MQTT on a pi zero that subscribes to the printer's topic to know when its done i got a lot of attention for my first video and i'm excited to keep sharing my work! thanks everyone 🙏
