Trying to figure this thing out. I guess I am going to add a stepper driver for the A axis. The stepper motor has to turn 36 rev for one of the chuck. When I put those numbers in the A axis setup screen it says at the top .5Khz pulses per rev. Does that mean 500 pulses per rev on the DM542T stepper driver?
Do not understand pulses per rev or where to get it. The rest of the DM542T stepper drivers are set at 1600. Of course those are direct drive.
I assume I must disable the Y axis somewhere when I use the Rotary?
The Pulses per Revolution is the number that you have set the driver too. The number that appears at the top of the setup screen is the result of the figures you entered.
The best thing to do is set the driver to the same settings as your other drivers and adjust the figure in A axis setup.
Pulses per Revolution is the number of pulses the driver will send to the stepper for it to complete one revolution. The fact that the steppers are direct drive or geared doesn't come in to it.
You shouldn't need to disable the Y axis as long as your CAM software produces the correct gCode to rotate the A axis.
You may need to adjust the figures in the A axis setup to calibrate the rotation.
Hope this helps you to understand.
