What is the problem?
Long story, while calibrating one of my MK3 (Einsy RAMBo 1.1b) the power went out, which caused some board failure (could not read some language file, on some chip.. etc) and would no longer drive the Y axis. So I ordered 2 replacement boards which are version 1.2e and had the MK3S Firmware loaded.
Installed the new board, performed a factory reset (all data); flashed the MK3 3.11.0 FW, and performed a full calibration.
The printer seems to work otherwise with the MK3 on board SD card, but Octoprint can't complete a connection with this software version.
What did you already try to solve it?
- Tried several USB Cables.
- Many changes to configuration in both OP and MK3.
- Flashed MK3 FW 3.10.0 - Regained Communication, but something was causing OP to loose communication during a print.
- Flashed MK3 FW 3.9.3 - Regained Communication and printing fine.
- Tried the same above with the 2nd new board with the same exact results.
What is interesting about this, my second MK3 with board 1.1b has no problem communicating with OP with MK3 FW 3.11.0. So there seems to be something different with the 1.2e boards?
Have you tried running in safe mode?
Yes, made no difference
Did running in safe mode solve the problem?
No
