General Mach Discussion / Introduction/question about Millpwr retrofit
« on: December 17, 2012, 05:20:12 PM »
New member here from Richmond VA, I run a small job shop with a few antiquated cnc machines, Bridgeport Romi w/ Fanuc Oi-T controls, Milltronics VMC 30 w/ centurion 6, Acer 2-axis retrofit with Acurite Millpwr, and the recent addition of a 5 x 10 plasma table that I built this past summer.  

The Millpwr unit has effectively lost it's mind and Acu-rite wants a little better than $10,000 to update the controls since they don't sell constituent parts only entire kits...  The analog servos are in great shape and the machine scales on it that are less than a year old, and after getting my feet wet with the stepper system I built for the plasma table I'd really like to switch the acer over to some mach3-friendly controls.

I've been reading about the dspmc from Vital Systems and from what I've gathered so far I think it's going to be my best option for controlling analog servos with separate linear encoders.  What I am unsure of is the general hardware profile that I will have to construct for interfacing the pc to the dspmc to the servos, ie. which drivers would be best suited for these motors (140v), suitable bob?
