FW 3.9.3 stability
I recently built my MK3S+ and it is working beautifully. It came installed with FW 3.9.2 which works well and is stable. I wanted to upgrade when I saw that FW 3.9.3 is available, but over on the GitHub site for the firmware, there is an issue about a FW 3.9.3 instability:
I wanted to ask in this forum if any members have experienced any issues with 3.9.3 on a MK3S+ while or after upgrading. Some of the issues were specifically on recent MK3S+ kits, so I don't want to take chances trying to flash the FW. Any confirmations would be appreciated.
When something goes wrong, you can go back to 3.9.2 easily. So just test it and see what happens.
Updated fine for me as well. Upgraded to MK3S+ parts, reset firmware to factory and reran the wizzard. All good. I did find that my Live Z is now lower (more negative) than before, but nothing wrong with that in itself. I did try putting the pinder slight higher up, but that then caused the nozzle to hit the bed during XYZ calibration. I suspect this is more an issue with differences between the PINDAv2 and the SuperPINDA which I swapped too than the firmware though.
I have the same problems with my mk3s as described on github.
@All, thanks for your feedback. I've updated my MK3S+ to 3.9.3 and the process went fine and the printer is performing as usual. Calibration was preserved as well, so all is normal and as it was on 3.9.2
