ok, than one permanent solution might be to add a few ferrites or chokes to the display lanes on the PCB for next generation S42B.

I experimented a bit with the OLED frequencies to check, if I can make an unstable setup with wire extensions in place. And it looks like I have been "on...

after 10h enabled on my desk without movment I get a very similar line shift as caesar  Will now increase timings more and check.

I digged into the digital communication now a bit depper and hopefully I can issue a PR next weekend. The display runs on an SPI 4-wire interface according p.18 of...

@swanepoeljan I am honestly impressed by your tool quality level here! :) And great to see, that my setup is somewhat showing at least a similar picture (just with far...

@caesar1111 as this is an open-source community there is no time pressure. :) You can grab the optimized code from my fork here: https://github.com/Quas7/BIGTREETECH-S42B-V1.0/tree/OLED_stability_optimization For me, that solved both kind...

@caesar1111 Thanks for the testing and feedback. I also ran into one interlaced-screen error after approx. 40h sitting on my bench but without any extension cables or beads in place....

@caesar1111 the OLED frequency will not solve this - there are other issues as well. I proposed a "fix" for the OLED issue in #20 This re-inits the OLED around...

what would be interessting is, if the issue also pops up in open-loop mode as well. I suspect that only the closed-loop calculations impact the software SPI implementation.

> @Quas7: Problem is, if the stepper is idle you will loose the values when re-init. and it will not help with the sever cases, where the screen goes black...
