I thought about using drawer slides, but since CNC machines make a mess I figured the slides would easily become clogged. Has that been a problem for you? I just tested moving a gantry using M6 1mm pitch threaded rod from my local hardware store. I wanted to be able to turn the rod once to move the thing 1mm. I found that 100 turns moves the gantry 103mm. Not accurate enough for me. Has this affected anyone else's plans?
