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.

I don't know why it does that, but setting the encoder scale to a
negative number will fix it.

If you can't fix it, you don't own it.
could you negate the scale of the encoder counter?

negativity should work, understanding would be more satisfying.

The counter mode counts up or down depending on the state of the B
encoder input at the FPGA (count up for high, down for low).
You can verify the B encoder input state by reading

2. Some configurations do not have B inputs as they are just used for counting
applications. In this case the counter will always count down (since
unconnected inputs are terminated in a 0 state internally in the FPGA)
