Hi everyone.
Having this problem - have posted on CNCzone, but don't know if it's kosher to link to a different forum, so I won't unless someone asks for it. Has a similar title as this one.
Anyway, running a Dell E510 Windows XP Pro, 2.92Ghz, 4Gb ram. Clean install windows. Nothing but OS and Mach.
I can get everything running, and everything runs great in driver test - all the way up past 60kHz.
I leave it set on 25kHz for now (for some reason if I up the kernel, I have to LOWER my speed in motor tuning or my motors lock up...that's a different topic)
So...for example, if I tune to max rapid at 100IPM when I jog I get 85 IPM. If I MDI a feed of 10 IPM, I get 8.5 IPM.
Very werid. When I look at the diagnostics, is shows I'm getting mid 21,000's kernel, not 25kHz. (21250 is 85% of 25000). It is pretty stable there.
I have tried converting PC to 'Standard PC' from a UniProcessor ACPI via a suggestion from Gerry at CNCZone. End result after some difficulty was still 21kHz, but it wasn't stable (if i just bumped my mouse it would drop to 100-300 Hz, then back up).
He said I must have a driver conflict somewhere. Any thoughts on how to fix this?
Thanks,
Doug
