General Mach Discussion / Pulse frequency in M3 is low. Driver test okay. Ideas?
« on: December 22, 2011, 08:11:09 PM »
Hi all,
I'm just trying to spin my first stepper. Im running a laptop, T43p, WinXP, I reverted AIPC to Standard PC, ran drivertest and came out as excellent. I checked my parallel port cable and had to change its port address (0x3bc not the standard 378) but am still getting errors. The pulse frequency reads somewhere between 1-150 hz, not 25khz, although every once in a while it will show it operating at 25khz for one frame but then revert to <200hz. No pinouts change when I try to jog.
Using KL4030s, C10 board and 425oz in parallel mode, DIPs set accordingly. Wiring is checked and good. Motors do receive power but will not turn.
Any ideas?
