Mucking about with a cheap chinese CNC
One of the offshoots of the rise of 3d printer tech is the proliferation of cheap "CNC" machines thet use the same control circuitry as a 3d printer but usually swap out the belts for drive screws and guide rails use a cheap spindle instead of the hot end and are usually constructed out of standard 2020 extrusion and a few machined parts.
I've seen these things knocking around but mostly assumed they were trash but their prices have been dropping a lot in recent years and you can pick one up for under 200 bucks.
