Ian,
Thanks for the reply, it is driving me nuts!
I was going by what the manual stated... The manual I've got states "3 slots at 4mm and one at 8mm" So I assumed one at 6mm would work OK. I figured it should at least work OK at low revs.
The CNC4PC C3 card I am using already has a Schmitt trigger IC on it.
Do I really need to set "pulley ratios" I have been just using pulley set 1 set to the maximum speed rating 0-3200 rpm Is this wrong?
What have you got the step/direction settings set for on the motor tuning? I set them up the same as the C11G manual suggests. e.g. 1000 steps per and 1500 velocity and something really small for accel (I can't remember off the top of my head)
Thanks
Simon
