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 ?
