I have been using an up 300 for about a week with some pretty good results, however yesterday things stopped working with the error “The main thread is blocked”
I saw a post here before that said to try to restart after receiving the above error
after restart received the error “Internal USB connection error”
and after another restart and initialization “Initialization printer failed”
Another subsequent restart and i can get to the point where I can extrude some filament then the machine dies and the screen comes back with “The main thread is blocked”
Any help? or does the machine need to go back for service?
