Spindle Pulses Lost in System

The counts are all negative, that is they get more negative when the spindle is turning. Same for the RPM. I have an entry in my postgui that flips it:

That fixes the display, but doesn't allow spindle synchronized motion.

The way to fix this is to set the encoder scale to -180

Yes, changing the sign on the scale flips over the following PINs:
   (all begin with hm2_7i92.0.encoder.00.)
   position
   velocity-rpm
   velocity
the change has no effect on:
   count
   rawcounts

As it turned out, I fixed it another way. I had the ESD button connected to the encoder-B  DB-25 P11 (14) input. I moved the ESD to my BOB #2 and left no input for encoder-B. This flipped the encoder.00 inputs to all positive and I was able to leave the encoder scale at +180..

Now I can thread again, so problem solved! Thanks for the help!
