If you want to get most performance from the PM 30 ( I have a similar one ) consider to learn scraping to make it a bit more rigid running. https://www.youtube.com/watch?v=ThJyxbSielE Uwe Interesting. I need to learn more about this. It's not readily apparent to me how scraping can increase rigidit...

Thanks Gary! Glad to know I'm not off base here.

Okay, so I'm slightly less dumb after spending a few more hours looking over documentation and planning. Resistive capacitive snubbers vs. freewheeling diodes were a bit confusing. For anyone who is in my boat and looking for the answer....a RC snubber is used to dissipate inductive kickback from an...

If you by all this stuff new, you will end up paying more than to do a retrofit of a used Brother TC229 (or similar machine) with Centroid CNC.... Uwe Uwe, Thank you for your comment. My parts list already has the PM-30V listed as purchased so I will be going that direction. I considered going with...

I couple of things to think about, I went with a PM25MV added a power drawbar and Tormach TTS holders. Now I am looking at a way to get higher spindle speeds. The FM30F would get me out of several problems (power drawbar, almost 10X the speed, speed control, encoder/encoder mounting and more torque...

My current priority is completing my electronics parts list prior to ordering everything. James's solution for limit switches and other associated connectors seems to be very elegant...but adding the design and outsourcing of a PCB to the list of things that I need to learn is a bit much I think? Wh...
