When I run in the other direction it simply shows 100 (not -100). One is cw, the other is ccw.
I don't plan to support reverse rotation, do I simply add that line "spindle.0.speed-out-abs" into the hal or are there other attributes I need to include with the addition?
btw, new hal with my newfound ability to turn spindle on via m3/4. Just no spindle speed controlThank you,
Dan

There seems to be an unused spindle pid in your HAL, slightly complicating matters.
You are using "output_type 1" for the pwmgen, which sets which pin is PWM and which is DIR. Are you sure that those match the breakout board's expectations?
If you use halmeter and turn the spindle on, do you see the pwmgen enable go "true" and the pwmgen.value go the require rpm?
