Hi guys. Before I get into sketchup(never used it) and stuff I'd like to run through a few ideas.
First off, i've never built a cnc machine before but have general skills, i'm always trying to build bits and bobs, I cant weld though.
Will 50mm angled steel be good for the base and also the gantry using only bolts, no welding. I have the usual tools, drills, angle grinder, taps etc. No pro stuff available though.
I've got 20 massive photocopiers that I can get my hands on for big steppers, bits, and possibly use the power supplies??
I want to use ballscrews to drive the gantry and router. I'm hoping it would be good enough to cut wood and ali to start of with and later modify the cnc to cut thin plate steel by getting a spindle etc later on. I'm hoping it will cost less than £1500 to build but most of all be reliable and accurate to around 0.05mm, is that possible?
For the size i'm hoping to make it 1.2m x 800mm.
