the 600 mm/s is only a rapid movement of the toolhead, not printing, it will run around 200 mm/s
I think the simple solution (after all you’ve been through) is to not move the toolhead that fast.
So to sum this up: you just did not try the right SGT value before or was there anything I missed here?
Sorry about that, just called my old parents. That always confuses me.
The second important thing is using DIAG0. Also see GitHub - andrewmcgr/klipper_tmc_autotune: TMC stepper driver autotuning Klipper python extra
Just looking at your table:
and I was thinking you might want to expand your variables a bit - try 0.6A for your run_current and 25 for your homing_speed.
These are the values that I am using and I’m getting a better range of values where StallGuard works instead of the single value that you’re getting.

HI @mykepredko ¨
so I did more tests and it’s the same, just too sensitive.
the best combination is marked “green”

Interesting that the chip is that sensitive to only have one working value for sensorless homing.
I don’t know what else to say other than I’m happy things are working for you.
