I purchased an Ultimaker 3 a year ago, and everything was working flawlessly out of the box. The day I upgraded to 4.0 from 3.7 the printer became useless. It would start up and go for 30 mins, sometimes 45 and then stop dead in it's track. No error code, no response on pushing any of the buttons. Sometimes it would just randomly reboot.. So I read this thread and downgraded to 3.7 and everything is working again. I have tried all the currently available versions of 4.x and all of them has the same issue.

Just want to add my experiences to this thread.
