I've started to order parts to do a second round retrofit. The original retrofit used a Campbell design BOB, Gecko G320 servo drives and was driven by Mach3. It worked ok but when I put it together I was not aware of most of the items that make up a complete control system. This TREE forum has opened my eyes and I hope to move toward a machine that is closer in line to the industrial grade controls that were originally there.
So far I have ordered a Centroid Acorn with the Pro software, a mini PC, DMM 3 axis servo kit with 0.75 kw motors and DYN4 drivers. I have a list started for Automation Direct..

Let the fun begin
