I thought granite devices are step/dir. (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.
