Constant layer shifts after commit 1d71610a4c61e47d07bca9dfe8dcc9041900c543 #144

Using this in config:

[autotune_tmc stepper_x]
motor: ldo-42sth48-2004mah
extra_hysteresis: 4

[autotune_tmc stepper_y]
motor: ldo-42sth48-2004mah
extra_hysteresis: 4

[autotune_tmc extruder]
motor: ldo-36sth17-1004ahg
extra_hysteresis: 1

I can't finish a single print because it just layer shifts randomly in the first 4 layers. Reverting to commit 1d71610a4c61e47d07bca9dfe8dcc9041900c543 solved all the issues so somewhere till 8db3476afd6a64db1d02218fbb92a8bb77da37cf something broke

I think i have the same issue, it seems that after each Z hop, Z level don't comeback to the same height and drift more and more.. resulting in a failed print.

For me it's not from Z-hop (I don't think). I have no Z stepper with autotune_tmc, i just get a random XY layer shift between layers 2 and 6
