Re: running the BDI EMC on a real machine

Jon....I went to your machining page and read with interest the Pico Systems info regarading the parallel port driven controller/drivers: 4 channel 16 DAC board, 4 channel 24 bit quadrature encoder counter board...plus other products yet to come...(ppmc set). I take it you will be writing drivers for EMC?? I would appreciate additional info as to application, availability, price, and how this board set will compare to STG-II. Thanx...Richard in Michigan.

I may be converting to BDI EMC using the STG II card within the next month or two. Jon Elson's Machining page discusses his implementation very nicely...although it was not clear if he was using stepper or servo motors.
