4 axis hot wire cutter

I’m thinking of taking what I learned from building the MPCNC and the low rider to build a 4 axis hot wire cutter. There are plenty of versions out there I could follow too.

However I don’t have multiple threaded rod for the z axis. Is it a terrible idea to use belts for the Z?

This guy uses belts.
CNC foam cutter.

I’m guessing that the loads are so light, that belts will be fine.


Nice find. Thanks. Yeah, loads would be light. Worth giving it a try anyway.
