Just adding to the issue: I did not reprint the same model because the customer accept it as-is (was not a issue) However, I still kept the same material and print 2 others models after. I did not have any problem. Is it posssible that there a thermal shutdown circuitry inside the Ultimaker 3 EX on the high voltage (light, motor, extruder) that could trip and the controller could not be aware of it ? BTW, is the log file show any clue ? Eric

Did not know if you need the config file too. flow_Ultimaker3ex.log ultimakersystem-ccbdd3003f32.5.2.11.20190503.boot0.log ultimakersystem-ccbdd3003f32.5.2.11.20190503.boot-1.log ultimakersystem-ccbdd3003f32.5.2.11.20190503.boot-2.log

Hi. Our compagny use a Ultimaker 3 ex for la long time (2 years) and this morning I witness a weird problem. I sent a 22 hours job print yesterday (small print). This morning, I was in front on the printer then suddently, it stop. Stop, meaning the the head stop moving, the top light shut down, the screen still continue his countdown too. I think it was still remaining 15 minutes to end the job. I think that LED of the head was OFF, so no heating too. So, for 10 minutes I let the countdown go. Just before the end I did touch the bed and found out that the Z-axis was not powered. I restart the printer and try to unload the filament: the head did not heat up. I restart the printer again, goes to manual setting of the printercore1, then unload the filament by hand (the wire was damage before the bowden). I reseat the printer head and check for bad connection: no problem found. I restart the printer and load the filament: everything turn good. Did someone experience such problem before ? Eric
