Stepper phase change

[nefelim4ag]

AFAIK, it should mean that the stepper made an unexpected number of steps.
So, the driver position does not equal the commanded one.

1. Try disabling interpolation. IDK, but if the read happens between steps, it can be unaligned, but should not be so high.
2. Try to set step_pulse_duration=0.000002 for Z steppers, just for the test.

On second glance, I think that tmc_autotune mess with TMC configuration, and enabled multistep_filt for some reason.

...
autotune_tmc set stepper_x multistep_filt=True
autotune_tmc set stepper_y multistep_filt=True
autotune_tmc set stepper_z multistep_filt=True
autotune_tmc set stepper_z1 multistep_filt=True
autotune_tmc set stepper_z2 multistep_filt=True
...

I guess you can report a bug to the tmc autotune github.

Just for the sake of mind map:

Z_tilt_adjust and bed mesh

Thank you for your input! On the first point, most of my work has been done cold, however there is a nozzle clean routine that raises the temp to brush the nozzle clean of filament. I will make sure things are stable during further testing, to avoid changes to the toolhead. When I perused the log, I did see those mentions of the stepper phase change, and was curious about its meaning. Your point that its affecting only two motors is a good one. I will look into this further. I wonder if bad ste…
