Thank you very much for your non help ... I configure myself my marlin for over a year and I have no problem except when there are some bug. before update no problem after I can not use the Linear Advance.

I found a solution for my config but I let you look for yourself on the forum if you want.

@Gerggg How did you resolve your issue? My impression was that Linear Advance doesn't work with stealthchop, and TMC2209 requires stealthchop enabled.

@Gerggg — Please be patient with our issue custodians. They do their best, and you failed to fill out the issue template according to instructions. Note that in the near future a robot will be closing issues that do not include an attachment.

As I understand it SQUARE_WAVE_STEPPING is very helpful for TMC steppers in-general and can resolve things like this. But we are very new to the TMC2209 and are learning which features work together and which do not. So in the near future we should be able to catch and prevent bad combinations of settings that cause these things.

Thanks for the report!

@thinkyhead - I did not understand the prerequisites for opening the case. I do not speak English very well. I opened a new bug with more information. the # 15692.

Thank you again for your work.
