Not much to it, really.
Basically, it’s a standard ATX-type power supply, with most of the crap cut off, and the power=good line soldered to ground.
That lets it run without being attached to a motherboard, and be used for lots of other stuff.
I googled info on how to go about doing this, here are the instructions.
I got the driver board assembled. I have yet to hook up motors to it, but here it is pre-burn-in.
Hopefully this’ll make a nice controller. I realized, though, that I need to find out how to get the signal for the dremel on/off to a relay or something. More research required. I guess I can figure out which permutation of machine I want to build and pick up some MDF and hardware tomorrow, too.
I got the main guts of the CNC machine in today- the stepper motors and driver board kit.
Fairly standard, as far as specialized electronics goes. The motors are ~300 oz-in, and the board can run 4 axes.
I’ve read through the docs, and it looks pretty simple- I should have it done and tested soon.
