The ppmc.0.encoder.03.index pin is something I can halscope easily enough. I

not just missing it with your scope parameters.
Well, the way the index pin works, it will stay true until
read, so it will always be one sample wide.
I’m sure the machine is homed because I tried to run G33.1 and it wouldn’t run
the command with the machine un-homed. I can’t say with certainty I have
enough travel but I do have far more travel than was being used.
OK, if true, then that kills the only idea I had. But, the
index function of the encoder would NOT have caused the
crazy results you showed in the video. Maybe some halscope
traces of the G33.1
would make what happened more obvious.
Note that Z moving downward is a -Z move.
