My Pm940m-CNC Finally came in and I though I would do an un-crating video with some talk about about the mill.

You do have to email and ask for the PM-940M CNC version as all they list on their website is the non cnc version. They sell both a VFD and a Non-VFD version.

I got the non VFD version and it was $7,347.00 with freight shipping. I went with the non VFD version as I eventually plan to run this machine on LinuxCNC and didn’t want to have to spend more to get a compatible VFD if the one that would of come with the mill didn’t work.

Today we’re converting a manual milling machine to CNC. We install high quality ballscrews, ballnuts, and angular contact bearings on first the Z axis and then the Y and X axis. We also install stepper motors. This video features tips and techniques that I have developed over the past 10 conversions or so. You’ll even see hardware from the first CNC conversion I ever did that was made on a manual milling machine. I learn something new every time. Please share your own CNC conversion tips and experience in the comments below.

This conversion utilizes the Centroid Acorn control board. Let me know if you would like to see video content on my specific setup:
