Just starting to configure a new build. This is first with dual spindles. I am not sure how to set this up and how to control the 2 VFDs. I have the 7737 step/direction boards with closed loop for the 6A motion. Was thinking I could use the other 2 available step/dir outputs to run each spindle as an OB motor - or maybe one on the 0-10V the 2nd as an OB motor.
How would I set this up, and how would I control each spindle? I plan on having separate M codes for each spindle on - say M13 for spindle 1 on clockwise and M23 for spindle 2 on clockwise. Trying to determine how to control how the S values go to the correct motor. I haven't had any issue setting up a single spindle in the past, just can't quite figure out how to set up the 2nd one.
