thanx, you can see above how really clueless I am on this

does the encoder 0V go to pin 9 like this?

Yes, that looks right

looks like its all working now. I can see all three channels in the HAL oscilloscope. Im worried 1800 pulses may be too fast, but Ill address that later. Next is the axis home switches.

1800 counts per turn should be fine, the 7I76e encoder counter can count faster than any standard encoder
(up to ~25 MHz). It may be that the encoder would need lower value pull-up resistors than the 7I76e's built in 2K resistors
if the count rate is very high but I don't think that would be the case with a lathe spindle.
