I recently had problems to comunicate with my printer. When I try to connect to it on server website, initially everything seems to be fine and State tab turns on "Operational" but after few seconds a messages appears:
" There was an unknown error while talking to your printer. Please consult the terminal output and octoprint.log for details. Error: See octoprint.log for details "
I attach the log file here: octoprint.log (515.3 KB)
I tried to reboot and shutdown the system, but nothing changed. I had the problem after I uninstall #plugins BetterGrblSupport, which I think was the cause of another issue I had recently (Z height on my Gcodes for printing was literally ignored). I removed it from Plugin Manager, checking the plugin and clicking on the bin icon.
I use the last Octopi (0.16.0), printer is an Ender3 but I created also a new instance for my Cr10 which actually is not working. I renamed (correctly) the devices ports into Ender3 and Cr10 to let Octoprint connect to the right printer after booting up.
Thanks in advice for your help,
