With 143e I just reprinted a 3 hour print with failed constantly 3 times before through OctoPrint. Using the same gcode.
During the first failed print (black PLA) it seemed like it went into crash recovery mode several times and it shifted the layers a couple of time. I let it continue since it seems like the part would still be usable (yet ugly). I then reprinted it with official Prusa PLA and left it overnight and came to the silver print. Update the firmware this morning to 143e, and used the same g-code as the previous and it printed flawlessly.
Previous Examples of the failed print:
Failed Print 1
Failed Print 2
Whatever you changed in 143e, seems to be working for my Setup:
Original Prusa i3 Mk3 Kit
Raspberry Pi 3
