Asking again. The only web link I found on this subject is 2 years old https://forum.linuxcnc.org/39-pncconf/32347-5i25-7i76-pin-axis-9-motor-pos-cmd-does-not-exist and their solution was not to use step/dir with the mesa board.
So is anyone actually using something like a mesa 7i92 with step/dir to the spindle? Or can someone explain why axis.9 is defined and how LinuxCNC attaches to it?
