CNC Milling Machine - Roland CAMM3 PNC-3000 Desktop Mill
It is a very sad day indeed.
Up for sale is my trusty Roland PNC-3000 milling machine.
The reason for sale is after 6 years of great service I would like to upgrade to a larger machine.
It is a small desktop mill, great for everything from simple 2D profiling or PCB routing, through to complex 3D milling in light materials.
Back in the day I have been told this cost over £13,200(!) new and was lightly used to cut just MDF in a school's Design & Technology department before I bought it.
The machine is driven by a standard parallel printer port and comes complete with a large set of Roland software for use with this machine. For 3D parts, if your current CAD system can export .STL files then the Roland software can import and machine the model.
Ideally this machine is suited for light materials, such as plastics, machinable wax, tooling board, MDF and high density foam; although I have made a fair amount of aluminium parts on it, there isn't a great amount of grunt behind the spindle motor (100W), so you need to take light cuts.
The stock toolholder collet has been replaced with a more durable collet I have had custom machined. Two are included should one ever get damaged. The collet accepts 6mm plain shank tools.
Two printed and bound user and service manuals will be provided; including full schematics. I will include all the latest software updates and drivers on a CD.
You can find a video of the actual machine booting up and homing its axes here:
It would be very easy to convert this machine over to run under Mach3 (to run full G-code programs).
All that would be required would be the swapping of one of the I/O expander chips (socketed) on the main board and hooking up to a parallel port.
Another CAMM3 user, Andrew Loen, who designed the drop in replacement Mach3 board, details this in full in his YouTube videos:

He also has a video of his CAMM3 being used as a laser cutter!

Please note: There is a slight issue with the machine in its current state. The X-Axis seems to occasionally and randomly miss steps when rapidly changing direction. I am unsure as to what has caused this issue. I have had a brief look at it, and have swapped over one of the stepper pulse generator chips with a known working one; and the issue remained. I can confirm the issue is not mechanical, as swapping the axis connection cords over, makes the issue occur on the Y-axis. Full schematics of the machine will be provided; I am sure it is such a simple issue to solve, perhaps a dry joint or something equally trivial I have overlooked. At the worst case, hook in a new stepper driver; and all is well.
Payment
Taking in account the minor stepper issue, I am asking £850 or best offer considered.
Delivery
Collection of machine preferred; will easily fit in the boot of a standard hatchback.
Will delivery locally (Nottingham) or further away at cost.
If you arrange your own courier, I will palletise the machine for collection.
Thanks for looking!
Any questions, don't hesitate to get in touch.
Best Regards,
Dan
