Printing a thing, namely one of the bases for the Petsfang -- not particularly big or complex, was taking roughly 2:30.\r\n\r\n#### What did you expect to happen?\r\n\r\nPrint finished\r\n\r\n#### What happened instead?\r\n\r\nOctoprint lost the serial connection to the printer.\r\n\r\n#### Did the same happen when running OctoPrint in safe mode?\r\n\r\nYes, both in safe mode and in normal mode with _all_ third party plugins disabled, and even some of the built-in ones.\r\n\r\n#### Version of OctoPrint\r\n\r\n1.3.8\r\n\r\n#### Operating System running OctoPrint\r\n\r\nOctoPi 0.15.0\r\n\r\n#### Printer model & used firmware incl. version\r\n\r\nCreality CR-10 running TH3D Unified Firmware, latest version -- U1.R1.8c.\r\n\r\n#### Link to octoprint.log\r\n\r\nhttps://gist.github.com/cassianoleal/971a6996a20852fc5bf513cb94e1843e\r\n\r\nI've also included `/var/log/syslog` in the gist.\r\n\r\n#### Link to contents of terminal tab or serial.log\r\n\r\nI'm *very* sorry but I lost this. There was not much to see there though, unless you wanted to analyse the actual Gcode being sent to the printer or the fact that eventually it stopped responding.\r\n\r\n#### Other information\r\n\r\nThis is a followup from my comment on #2647 . As it was correctly pointed out by @foosel that bug was specific to the server dying in response to a failure.\r\n\r\nI have now been running Octoprint 1.3.7 on the same setup with no issues so far.\r\n\r\nI'm running on a Raspberry Pi 3 B+. The Pi itself is powered by the official PSU, which solved problems I had in the past with power fluctuations -- I'm not seeing those anymore. I have the printer and a Logitech C270 webcam both connected to a powered Anker USB hub with new high quality cables. Nothing else is connected to the computer.\r\n\r\nEverything is up-to-date. After the issue I ran `apt update` and `rpi-update` and neither had updates to be done."},"comment":{"url":"https://api.github.com/repos/foosel/OctoPrint/issues/comments/390944812","html_url":"https://github.com/foosel/OctoPrint/issues/2658#issuecomment-390944812","issue_url":"https://api.github.com/repos/foosel/OctoPrint/issues/2658","id":390944812,"user":{"login":"JabawokJayUK","id":7078073,"avatar_url":"https://avatars0.githubusercontent.com/u/7078073?v=4","gravatar_id":"","url":"https://api.github.com/users/JabawokJayUK","html_url":"https://github.com/JabawokJayUK","followers_url":"https://api.github.com/users/JabawokJayUK/followers","following_url":"https://api.github.com/users/JabawokJayUK/following{/other_user}","gists_url":"https://api.github.com/users/JabawokJayUK/gists{/gist_id}","starred_url":"https://api.github.com/users/JabawokJayUK/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/JabawokJayUK/subscriptions","organizations_url":"https://api.github.com/users/JabawokJayUK/orgs","repos_url":"https://api.github.com/users/JabawokJayUK/repos","events_url":"https://api.github.com/users/JabawokJayUK/events{/privacy}","received_events_url":"https://api.github.com/users/JabawokJayUK/received_events","type":"User","site_admin":false},"created_at":"2018-05-22T10:39:04Z","updated_at":"2018-05-22T10:39:04Z","author_association":"NONE","body":"@foosel for clarity I have only tested this on OctoPrint 1.3.8 running on OctoPi 0.14.0."}}
