www.rogersmachine.net. Not true closed loop, but it will monitor potion and notify mach3 to stop if an error occurs. I don't know of any true closed loop DIY stepper systems.

Atleast one person has done it with emc2.. (using encoders to trip a following error realtime.)

(I don't have a bob solution.. I think he hooked them directly into the printer port.)

Some light reading...
