Hi,
I didn't notice an issue at first with the 45kHz until it tried to move 2 axis at the same time. Most of my testing was just a single axis before that. When doing 2 axis at the same time, it would make that horrible seizing up type noise. I was hoping that there was an explanation for that noise (and that others have experienced it, know what to call it, etc.). At this point I don't know if it is anything but the driver itself sending commands that don't make sense when it is configured for 45kHz. I've been tempted to connect up turbocnc and try doing multiple axis at the same time at that speed to see if it does the same thing to prove whether it is a driver issue or something else.
Using 25kHz, I can tell all 3 axis to go at the same time using G00 and they all move perfectly. I repeated this back and forth at 120 IPM a few times with no problems...
Thanks,
Alan
