My apologies, if I am missing something, but th
negativity should work, understanding would be more satisfying.

could you negate the scale of the encoder counter?

First, the Hurco is alive! I carved emc/axis into a piece of aluminum
yesterday; thanks to all the participants for creating & supporting
emc/lcnc/linuxcnc/etc.
Now to the next level - I'm using a hall sensor to detect spindle rpm; I
get a clean low-going pulse each revolution, as expected. Th
