# spindle speed display net spinraw ppmc.0.encoder.04.delta conv-s32-float.0.in net spinfloat conv-s32-float.0.out mult2.0.in0 setp mult2.0.in1 185.185185 # (60/encoder count/rev) net rawSpindleRPM mult2.0.out => lowpass.1.in setp lowpass.1.gain 0.02 newsig SpindleRPM float linkps lowpass.1.out => SpindleRPM Now, in this case, the spindle encoder is connected to an encoder input channel on my ppmc boards. I convert an integer encoder raw counts per servo cycle output to floating point with conv-s32-float, multiply by a constant calculated to give the right spindle speed, and then feed that to lowpass to filter the jumps out. If you need help with the other parts like loading the hal components, let me know.
