Good ol' Mach3. I did a conversion on a BP mill that runs great, and was cheap, about a grand. I'll have to plead ignorance about the software you are asking about, I only have a copy of the original EZ path Ver 2.08, and I haven't been able to get it to load yet. Get a sector missing error??

Sorry CPatten, didn't mean to hijack your thread. I looked at the All-in-one Centroid conversion, and it looked pretty easy. My problem with it is that you retain your old servo drives that are expensive to repair if they go down ($700) and if the all in one board quits, then more big bucks. I am a hobbyist so it must be cheap, you on the other hand may be using it for business and can justify the expense. I think I will try and do a conversion using Mach3, Geckos, and hobby type hardware where no single component in the system costs more than $175 to replace.
