Hi all,
I had the issue yesterday for the first time, during the print the connection with the printer was lost after a few hours. If I remember correctly, the message was "TMC Connection Time Out". After this I've started a new print that ran later that evening, without any issues.
So after that I've started a new print, around 10:00 in the evening, and I've checked the print a few times today (using my VPN). But now I see the printer has stopped, so I think the error occurred.
The only thing I can think of is that I've installed a plugin showing the % in the browser navigation bar. So I've deleted this plugin.
But when I am checking the logs, I see a lot of warnings and at 13:29 there is the follow message in the log:
2020-02-03 13:59:28,945 - octoprint.plugins.DisplayLayerProgress - INFO - Printing stopped. Detailed progress stopped.
2020-02-03 13:59:28,956 - octoprint.plugins.excluderegion - INFO - Printing stopped: event=PrintFailed
What can / should I do to solve this? It was a 18hour print, that stopped at about 15 hours. So I feel kind of sad
This is a part of the log, around the mentioned time stamp:
