3D printer/laser engraver electronics are great for lots of things actually. You get A (at least) 3-axis motion control system with G-code processor Spindle controller (usually) Limit switch input A nice graphical display (Sometimes) Wi-Fi or BLE Arduino framework All for around $50. I was exploring the use of one for an open-source infusion pump controller. However, it turned out to be too bulky, but it would probably have been fine otherwise. Even after all these years, I was blown away by the insane amount of capability that I could buy for $50.
