2 steppers on one axis 5i25 - 7i76

well if you still have the original code why not try the one line change - it may be enough.

If you want the added feature of master then go that route but a small warning Master is not released code, and had big changes in it. The guys advocating using it are very experienced. I'm sure with their help you will get there but be prepared for the time investment. There are a lot of little thing to learn on the way.

Rodw: maybe with your help I could add a tandem capability to pncconf's master branch.
I need a working sample config to see the differences.

definitely want to go the easiest route. I found this .hal file. Is this how it should be set up?

Sorry if I caused confusion with my previous post. I started this saga on 2.8, so it's all I know. If you're going with 2.7, my suggestions don't apply.

Rodw - per your prior comment on single-axis jogging behavior, I upgraded to latest 2.8 master and an error dialog pops up to intercept the badness now. As you predicted, it's fixed.

I'm sorry I think we are getting you (and me) confused.

The file you just posted seems to be a hand written file - looks like from 2.8 (master).

The one line change I was talking of was for the 2.7 version made from PNCconf that you had already did a little hand edit on.

Please choose which version of linuxcnc you wish to go with 2.7(released) or 2.8 (master/development) and then one of us will advise you from there.

Ok, I updated to 2.8. I think I want the joints. I created a .hal and .ini file in pncconf using the X Y Z A. How do I convert the A to a Y?
