Hi all a complete newbie here...

Years ago I wanted to build myself a CNC machine for PCB as well as cutting some aluminium panel for project boxes. I built the alegro 3977 controller and my only 2 samples blows and that puts me off CNC building for a while along with other things.

So anyway I think Im gonna start the project again.

What I have right now is 3 stepper motors, spec is 1.8deg 2A 1.4NM. I also managed to buy more than enough L297 + L6203 from ebay very cheap. Designing/building the controller, breakout board and the PSU isnt a problem as I already have most of the parts from other projects.

I need something like 12" x 9" x 2" work area. Cutting/drilling/milling PCB as well as aluminium and plastic up to a thickness of 2-3mm.

Are the items below suitable for what I need >>>

20mm rail + linear bearing
12mm x 5mm ballscrew
120w spindle

I can live with slow machine as long as the work get done. Please advice

Cheers
