Anyone here familar with or know anything about CNC4PC's Manual Pulse Generator seen here:

It's supposed to work with MACH3 through a 2nd LPT port. I know I need an MPG bad because moving the machine around with the keyboard or mouse just doesn't cut it anymore (TOO SLOW!)

You could get a Shuttle Pro on Ebay for about $75. Lot's of people using them with Mach3.

Thanks for the info Gerry. I appreciate the tip very much. But being used to the full sized, 100 click per rev dials on the big machines I think this is the best alternative. I definately like a dial better than arrow keys. I just wish I knew if the thing really works. The company is in the UK but after talking to them on the phone today I guess I am going to go for it. I will report back here and let you guys know the results.
