In this video I wanted to make a heated build platform for my cheap 3D printer, but got distracted by another interesting feature of the Cetus. It has an unused output on the print head, that can be controlled from within gcode. That opens up a ton of possibilities, but what I am most interested in is, as always, laser PCB prototyping. Will that work? Spoiler: Yes, it will. Incredibly well.
