Solved! I was using *spindle.M.speed−cmd−rps *to drive my stepgen and VFD and this pin sets to the maximum speed when in G96. I'm now using *spindle.M.speed−out−rps *and it works perfectly. But that makes me question the naming on these pins. Aren't all the CMD tagged pins supposed to be used to feed PWM, Stepgens, etc?
