Well, I finally did it! I yanked the ancient 100 MHz Pentium classic computer out of my Bridgeport control cabinet and put in the 600 MHz Pentium 3 with 256 MB of memory and EMC2. It took a while to get the feel of tuning that system with its velocity servo amps, the P term is set a LOT lower than with my PWM sorta-torque mode amps. I finally got a decent tuning solution and get under .001" error at 50 IPM. I can live with that, it is a lot better than the old EMC with STG board.
I still have a bit of work to integrate the home and limit switches, but I mocked up the home switch and tried to search for index. Maybe I have to have the home switch shut off before it will sense the index, I'll try that tomorrow. I put in an ancient VGA card in place of the mobo video, and I saw no real time overruns in 8 hours working with EMC2. So, it sure looks like the mobo VGA that is used in Dell i810 systems is the culprit. Probably the VGA doing some kind of bit-blt operation and slowing down CPU memory access. So, all of you guys who had been bugging me to upgrade that Dec-20-1999 version of EMC can now relax. It was only used for SEVEN years!
