Sorry Jon;
I just figured out what you were asking.
There was no error message.
The Homing process was seeing the plus level of the upside down
Index pulse and setting the HOME-OFFSET immediately after
Home switch release, instead of at the Index Point -1.9 inches away.
Thanks again

Hi Jon;
Yes, I was totally ignorant of the problem and only understood the
symptom at that time.
I had checked the Index Pulse, at one point, and it was going
negative active like the other Bit inputs into Motenc.
Until I saw what a working .hal setup was, I focused on the
setup as the problem.

Thanks to all who helped with this problem;
My limitation was a lack of experience with EMC, plus:
There is documentation on how to setup the .ini file.
But I could not find documentation or examples how to
setup the .hal file for that configuration. It wasn't working
so I assumed something was mi
