i have a MK3 which is about 2 months old now.
Since about 2 weeks i have a problem... when i print bigger prints (different one) after a few hours the noozle temperature drop to 0° and the fillament get stuckt in the extruder. The printbed stays on 60°. I checked also the casbles from the extruder but they are ok.
I have also a new second printer where i can print without problems. Both printer run same firmware 3.4.1.
Can this be a problem of the EINSY RAMBo motherboard?
Thanks in advance!
