I have searched through many posts, and ordered some parts - but somewhere inbetween my studies, my cnc plans was laid to rest. I'm going to finish it now and I plan on making this my build log. Having a place to store links and ideas is needed, and this log will function as that.
Build name: A4
What I would like to achieve: Fine precision, A4 working area, 7 cm Z-axis, pcb double sided milling, jewelery wax milling - that's about it.
So far I've collected 4 8Amp drivers, totally overkill - but they can be current controlled down to 0,5A. Three huge stepper motors (8 wire) I'll use two, one for each side, for the y-axis (longest). I'll use one for the x-axis and I need one more for the z-axis.
Cupboard slides, I've got a ****load of them. I plan on using these in the z-axis. I'll add solidworks drawings later. Rack and pinion gears in steel will be bought from McMaster-Carr. I'm thinking of letting the whole "arch" (y axis)rest on 4 rather large standard gears. Cupboard slides will be used for x-axis.
Firstly I'll use a normal dremel tool, but I plan on upgrading this to a better one after a while.
I'm thinking about using the usb solution planet-cnc offers. But this is still to be planned better.
Thats it for now. I hope to come back with solidworks drawings and pictures after building is commenced
