Constantly forcing index-enable low would explain the issue with G33.1 in the post above:

Have you tried using spindle synchronized motion (eg g33 or g33.1)?

What makes me wonder is why constantly forcing index-enable low does not cause a problem for you.
You are right. I haven't used G33.1 yet. Will test it soon.
But from the looks of it, this is not easily solveable --> need to disconnect the index somehow...
EDIT: Could we write a switch component that passes the signal in both directions (similar to mux2 but bidirectional... ) ?
EDIT2: The easiest solution for this is to probably just install a optical sensor as a second index signal... and then use this for indexing in M19 or for G33.1 ?

the index-enable pin is of type 'io' which _is_ bidirectional. All you need to do is move the line 'index-enable = 0; ' inside the 'if (enable)' block as in my version (or possibly just remove it as the user in the post I linked above.

Thanks for that.
Will test it this weekend.
