What is the problem?

After I updated to octoprint version 1.9.0, Octoprint is Force-sending M112 command to the printer at start of print job. Previous versions of octoprint worked without any issues.

What did you already try to solve it?

I rebooted octoprint into safe mode and printer seem to print without issue. I've can also print successfully directly from my Ender 3 3d printer.

Have you tried running in safe mode?

Did running in safe mode solve the problem?

yes

Hello @Loren_Melton !

So one of the 3rd party plugins is the culprit.

I assume it's this ridiculous long message for M117 that the printer firmware complains about.

Please use shorter filenames with no spaces.

Try with disabling the Dashboard plugin.

I kept getting the warning message "Printer keeps requesting line 22 again and again, communication stuck" then octo print forces a M112 command to shut down. So I restarted octoprint in normal mode after getting it to print in safe mode and disabled all 3rd party plugins. I've been enabling the 3 party plugins one by one until I find the culprit. So far I got it to print with the Dashboard Plugin and the runout sensor plugins enabled.
