I've been using Octoprint since November on my Ender-2.
Unfortunately a hardware failure meant I had to replace the printer board, and was sent the newer board (Creality V1.1.2) which doesn't like the smaller screen.... so it all works, but I can't see anything on my display.
However, I've been ok controlling it with Octoprint on my Zero-W without any problems. Trouble is, I didn't realise you're supposed to shut down before powering off and corrupted my sd-card. Lesson learned.
I've got a new card, re-installed Octo and allowed it to update. Trouble is, now it won't connect to the printer and comes up with the error "Offline (Error: SerialException: 'device reports readiness to read but returned no data (device disconnected or multiple access on port?)' @ comm.py:_readline:2417)"
I've tried the things I've read about, but nothing has worked;
It works fine direct to the PC and prints via my slicer on there (though it doesn't have the printer controls that Octo gives).
I've tried a different power supply (though I've been using the same one that been fine so far)
The cable is ok, as it's the one that works with the PC.
No changes have been made to the printer from when it was working previously.
I've tried manual settings instead of auto.
With the printer power off, plugging the Pi in powers the board as it always has.
Any help would be appreciated
