You just set ppmc.0.encoder.xx.scale to the number of counts (encoder line count *4) of the encoder. > Also, another question.

Then, there's some more that rigs up a DAC channel for the spindle speed command. Right now it is dumb, and ignores the belts and back gear. And finally some stuff to prepare a speed signal for pyvcp to put on the screen. Files spindle.hal and spindle.xml actually get it on the screen.
