[QUESTION] Using TMCStepper 6.0.0

[damvcoool]

Hello BTT team,

Since teemuatlut has release TMCStepper 6.0.0, with WriteOnly Feature removed
teemuatlut/TMCStepper@63d0ef5

Is it still needed to use the custom (and outdated) TMCStepper from BTT?
https://github.com/bigtreetech/TMCStepper

I will be testing this later today, however some official documentation update, would be useful for future buyers.

I think we are still tied to a custom TMCStepper as long as @bigtreetech uses a custom swserial.

It would be nice if we could use upstream TMCStepper and Marlin though, maybe if we pull swserial from something else - like FYSETC does:

I believe they are working on that with this PR
MarlinFirmware/Marlin#15655 (comment)

F.Y.I. the PR in this lets us use the upstream TMCStepper and Marlin cleanly, worked for me.

[swilkens]

The changes proposed in MarlinFirmware/Marlin#15875 have been merged in upstream Marlin.

For the v1.2 mini, we can now build Marlin-2.0.x upstream with upstream TMCStepper for this board without the need for BTT's forks.

I am compiling this with my settings right now... for reference these are the settings i am using.
I Use a BLTouch, and also changed platformio.ini to use teemuatlut repository directly.

Once i get back from work i will install the bin, and test with a Benchy.

I think there is something wrong with my configuration...the Printer Homes, then Bed Levels, however when printing, it's fine for the first few lines and then somehow it forgets where home is, by what i mean by that is it's supposed to draw a line that's 30cm long, and when it gets to about 20cm, it starts to execute the next command, stopping the print at this point and looking at the x,y possition it seems that it's off from where it should actually be.

I can't seem to find what may have i configured wrong.

Also with the configuration i posted it seems we get the TMC Connection Error.

[swilkens]

There is a small issue with the new TMCStepper version 0.6.0 that came out recently that causes connection errors.

teemuatlut/TMCStepper#93

For now, this can be fixed by changing your platformio.ini file to have TMCStepper@=0.5.2. Then, it should work properly again.
