Hello all! I am well along in the process of converting a PM25-MV to cnc. All that is left is to figure out the spindle control. I am using a acorn board, but I unfortunately do not have the original DC motor controller that came on the mill. I was wondering if there are any off the shelf drivers that would work with the 750W motor, and take a AC input. As well as is able to take the 0-10vdc spindle control from the acorn. I have been having a real tough time trying to find something, and have reached out to PM for a replacement, but would really love something a bit more purpose built vs hacking together the PM25 board with a isolator.


Thank you very much for your time!

I have this; Franco on the Centroid forum has a PM25

Yeah I have seen that one, I don't have the original speed controller so I need to replace that with something as well. I was hoping there was a option that combines both the isolator and dc controller itself!

Look at the KB-SI-5 which I believe is an isolator that attaches on top of a KB DC motor controller

Awesome, so its probably the same dual pcb situation as using the stock controller. I sent Galco sales a email, hopefully they can give me a hand!

Thank you for your help!
