The question of proper threading

I would have thought that changing the sign on scale would have done it.

I did it. This did not change, but I wrote about it above.

I checked two times more.

Changing the sign on scale does not affect count only position. Looks like position=count/scale

I use halcmd to change. May be I need to restart axis?

You can use the calibration menu (machine/calibration) for axis changes and tuning, not sure if it can do that for spindle.

you have to restart the gui for them to take effect

Only the position is used so the count and rawcount pins are not relevant
