Hacking a Roland CAMM3 PNC-3000

[Snowy]

Hi Robin,
That would be awesome, yup, up for it.
My machine turns on, homes and the spindle test function seems to work ok.
I've not found much on line but what i have shows a seperately removable front controller and stand alone computer/psu, mine has none of that, suitably blurry picture attached

Disappointment, that is not a PNC-3000, can't use it, sorry to get your hopes up

well thats a bit of a scunner, had my eye out for 1 since reading this post many moons ago.
Do you know anything about the one i have? all seems abit secret squirrel club. At least it was dirt cheap, might be a base for something slightly up from the tat you can get new from ebay.

If you fancy any of this stuff let me know, i'll never be able to sue it -


Do you have any info on the Sanyo steppers? must be too old to turn up much on DuckDuck
Sanyo Denki
Type 103-594-01D1
2ohm
0.9 deg/step

I just bought a Ronland PNC-3000. I have searched a lot of documentation about it but to no avail. Currently the Yahoo groups you share are locked. Do you have a user manual and how to install the software to connect to the laptop. ?

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.

There is a User's Manual, a Command Reference Manual, and a wedge of Technical Reference including full circuit diagrams and PCB layout.

Once I saw a schematic with a Z80 I just had to hack it. Didn't worry about the rest,

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