      Hi,
      while this is an older thread, the problem itself is very current, unfortunately 😞
      While I had it for an Anycubic Mega S printer, it was basically the same root cause. I solved it w/o having to replace any hardware, but with some additional mathematics to compensate for the rod twist. I wrote something up explaining the issue and also provide there a little online tool to create appropriate compensation GCode commands. This works great for me and I have no more issues with the bent hardware, so maybe it is a proper resolution for some of you also... 😊

      Regards, habitoti

      I suggest that for the moment you leave out the G29. Run G32 and see what it says the deviation is before and after (after should always be zero if you have only 2 probe points). Then run it 2 or 3 more times and see what deviation it reports after each one. Depending on your mechanics, it may take a few runs to converge.

      There is an extra M671 parameter in firmware 1.21RC3 to help with convergence.

      @dc42:

      1. You can use F0 for homing and F1 for stall detection, if that helps.

      2. Have you tried using S2 but either decreasing allowed acceleration (and maybe jerk) or increasing the H parameter in M915?

      Will try both and report back, thanks πŸ™‚

      Testing wifi so far…

      Restarted duet 10 times, 5 worked, 5 failed (50% of the time...).

      Interestingly, 1 fails, 1 works, always doing more or less the same (turn on, wait until connects or fails, wait ~20s, turn off, wait ~10s, turn on...). At least, works more often than before...

      I moved back to 1.19.2 (both, firmware and wifi), and repeated the testing 6 times: 100% connection success

      It shows "Connected", then "Wifi Module Started" (this is not shown in 1.20), then "Wifi Module connected to Access point" (ping start answering), then 5 seconds after this, ping start to fail, and screen shows "Error retrieving wifi status message" and then connects again with "Wifi Module connected to access point" and don't fail anymore. After the third reboot, "Error retrieving wifi status message" didn't show again, and wifi works perfectly fine.

      Moved to 1.21RC1 and again, one works, one fails... so I don't think this is hw related :S

      Can I give you anything else for diagnostics?

      Regards

      Uhm, I will check today again, but I think that Z head position was reporting 0.22 before I applied the BabySteps.

      Thanks!
