Need Help!- Mach 3 No control on Win2000

[Biff.Hansen]

I tried running Mach 3 on a Dell 3.4ghz P4 with 4gb of memory running XP and never could get it to drive my system. Moved over to an older PIII 1ghz w/ 512mb on XP and it works fine. I aquired a newer handmedown dual Zeon 2.0 ghz w/ 4gb that I've got Win2000 server running on and am back to the same problem. It sees my E-Stop button cycle. I run drivertest.exe and it shows excellent at about 23303. Tried msconfig, shutting down almost everything, no change. Parallel port address is correct, I'm at a loss. Any ideas would be appreciated. Thanks Biff

Not sure if Mach runs on 2000 server? Although if the drivertest works, I guess it should.
Have you tried using outputs, and measuring voltage on the direction pin while jogging? Do the DR's change? Is the Estop wired to an external switch, or breakout board?

DRO's change, no activity on port lights on diagnostics page, though when I hit my external Estop (13) switch port 13 changes status and Mach3 responds to the Estop. Estop is has two spst switches, one kills the SloSync Drivers, the other goes to my breakout board to parallel port pin 13. I had my O-scope on it when it was doing this on XP, but I don't remember the results. I'll put it on tonight and see what I'm getting at the breakout board.
