[BUG] TMC2209 not working anymore after version upgrade

[igna09]

Did you test the latest bugfix-2.1.x code?

Yes, and the problem still exists.

Bug Description

I used my printer with Marlin 2.0.5.3 and TMC2209 (X, Y, Z, E) without any issues Today i decided to upgrade to bugfix 2.1.x porting old configurations I noticed that homing (sensorless) was not working anymore I executed M122 I S0 and noticed two strange behaviours:

• despite S0 flag it continue to output values instead of stopping
• current values was wrong I tryed with M502 to restore configurations from configuration.h and configuration_adv.h but nothing changed

So I decided to downgrade to 2.0.5.3 and everything is working again

There is some breaking change (about trinamic) upgrading from 2.0.5.3 that I'm missing or is this a bug?

I also checked that connection is working, in both versions i can read registers correctly

Could you be more precise about what's not working? Also, try a minimal configuration from a fresh configuration file (just enough to run homing) and see if homing works. Enable DEBUG_LEVELING_FEATURE, then M111 S247 and then run G28 to see if you can spot anything obviously wrong ^_^

Same for me. It was working in 2.0.5.3 then I moved to 2.1 and it's not triggering, even if I set the sensitivity to max. I went through old versions and it seems it doesn't work from 2.0.8 Not sure if what is supposed to be set for that has changed or not.

My build, STRING_DISTRIBUTION_DATE "2024-01-24" of SHORT_BUILD_VERSION "bugfix-2.1.x" using sensorless homing for both X and Y on TMC2209 drivers.

I have no issues.

It took a lot of testing, but I did finally get mine working. SKR1.4, TMC2209, BL Touch, CoreXY, Marlin 2.1.2.1: Configuration.zip

I particularly had issues with stealthChop and hybrid_threshold. Depending on what they were set at, the sensorless homing didn't work at all. I had to disable them entirely, or lower my microsteps from 256 to 64. Hopefully these files might help you.
