Lathe stops at code line

I have getting it to work now!
On the mesa 7i76e board there are 3 Jumpers. W10 W11 and W13.
on the left is single mode, to the right is differential mode.

in halshow i can now see the position and the channel A and B signals.

unfortunately no Z Index signal and no real time rpm.

It is practically impossible to see a Z pulse.

You can test by using halcmd to setp the index-enable, then turn the spindle by hand and watching for index-enable to go false again.

Does your spindle position increase by 1.0 per turn?
