Hacking a Roland CAMM3 PNC-3000

[Snowy]

Hi,
From what i can gather details are sketchy and if you have to ask it's probably beyond you (and me!)
I just missed out on a PNC-3000 on ebay, went for too much in the end but i was going to convert it to Beagleboard or something arduino based due to the above.
My mis-fire with the purchase of a roland CNC is crawling along with re-wiring due to lack of foresight on my part with ordering bits. It's a weird machine using wires to pull the various axis and then springs to return it(?) not sure it'll be much use beyond an exercise in converting and fiddling about. might try to add a acme thread and nut assembly later on.

Best of luck, perhaps someone better informed can help you out.

PS: The steppers have a glorious, 400 full steps/rev rather than the usual 200. The inverse square law kicks in and they purr.
