Without seeing the HAL I can only guess, but I suspect that you need some "abs" functions in the HAL that creates the at-speed signal.

You could try changing
in your postgui file such that it usesBut that might make it not work in either direction.
If so then it probably means that your spindle encoder is counting backwards, and you need to set the spindle encoder scale to -400
net spindle-cmd-rps-abs => near.0.in1
net spindle-velocity-feedback-rps => near.0.in2
net spindle-at-speed <= near.0.out
setp near.0.scale 1.200000in your postgui file such that it uses
net spindle-cmd-rps => near.0.in1If so then it probably means that your spindle encoder is counting backwards, and you need to set the spindle encoder scale to -400

net spindle-cmd-rps => near.0.in1 didnt work but -400 did!
