I have looked at both thanks for the feedback. I am trying to weigh my options. I have a MESA 5I20 that I am currently using mostly for general I/O for the toolchanger but also planned to use it for the AXIS control. I am looking for the best bang for the buck. I am not finding very many companys that offer big enough drives for the size motors I am using... I actually hope to do closed loop when all said and done....

(well - I guess I don't know what the OP was thinking.) If I was going that route - I would get one of the servo interface solutons for emc (pico systems, mesa are probably the biggest - I use mesa) and some analog drives. (or mesa and pico have drive solutions iirc) I would seriously look at running true closed loop (not step/dir drives) It take a little more work to setup - but having encoder feedback directly to emc has so many benifits. On my conversion - I am using mesa interface hardware and analog AMC servo drives (ebay purchases). Very happy with it. sam On Thu, 18 Aug 2011 10:23:55 -0600 "Jarrett Johnson" <[email protected]> wrote: > Check out Granite Devices, great boards and good support.
