This continued for approximately 1 minute before it got turned off. this information is what could be gleaned from the last few frames of the time-lapse and the amount of filament extruded below the print head (about a meter of extruded filament from the 0.4 mm nozzle).\r\n\r\nabout a hour latter I had time to start it back up and diagnose so you;'ll see that timestamp gap in the log file.\r\n\r\n#### What did you expect to happen?\r\nthe print to execute gcode correctly\r\n\r\n#### What happened instead?\r\napparently, there was an error sending the gcode to the printer according to the log.\r\n\r\n#### Did the same happen when running OctoPrint in safe mode?\r\n\r\nUnfortunately, I have neither the time nor material to test this error in safe mode. \r\nThe nature of the problem makes it unlikely to be repeatable.\r\n\r\nin retrospect I'v had a similar issue in the pased on octoprint 1.3.2 but at the time I assumed it was a problem with the zprobe ceatching on the print or somthing (a possibility that has since been removed as an option.)\r\n\r\n#### Branch & Commit or Version of OctoPrint\r\n\r\nOctoPrint 1.3.4 (master branch)\r\n\r\n#### Operating System running OctoPrint\r\n\r\nOctoPi\r\n\r\n$ uname -a                                                                                                                                                                                        \r\nLinux octopi 4.1.19-v7+ #858 SMP Tue Mar 15 15:56:00 GMT 2016 armv7l GNU/Linux\r\n\r\non a raspi 3\r\n\r\n#### Printer model & used firmware incl. version\r\n\r\nANet A8\r\nMarlin SkyNet3D-V2.3.2 (Github)\r\n\r\n#### Browser and Version of Browser, Operating System running Browser\r\n\r\nGoogle Chrome\t58.0.3029.110 (Official Build) (64-bit)\r\n\r\n\r\n#### Link to octoprint.log\r\n\r\ngist contains multiple files:\r\nthe full log, the log truncated to the last two boots, and the relevant error section\r\na sequence of screen grabs from the time-lapse (10 seconds apart)\r\n\r\nhttps://gist.github.com/Ryex/d7130aeb9a2a5154339a12afc95fa680\r\n\r\n\r\n#### Link to contents of terminal tab or serial.log\r\n\r\nsadly I do not have a serial.log nor can I get the terminal tab as the printer and pi were on the same power source and the power was pulled to prevent further damage to the stepper motors.

Happened about 4 times now while using Printoid Premium. Nothing obvious in the Logs except the Snipped that was already provided here.\r\n\r\nI have the feeling it happens mostly with recently uploaded gcode where no estimated printtime is calculated yet. Don´t know if that helps but if Printoid could be the cause I will try to print my next files directly from Octoprint Frontend without using Printoid.\r\n\r\nBtw: I´m running Octoprint Version 1.3.6 and Printoid Version 9.11 which was just updated about an hour ago and still have the same issue."}}
