Firstly, nice work on this firmware.
I have a small 3 axis mill and would like to do some tapping. Currently using firmware-cnc-latest.bin as of 7/14/20 and have an encoder on the spindle to track the position. Standard 2 channel (using 1 channel now) single ended 360 cpr. In the spindle module I have set the spindle.feedback_pin and spindle.pulses_per_rev but would need a way to access the count to tie it to the Z axis. Is this possible to do currently?
