MK4 - A lot of issues [90% of prints failing]
Hi, got as a present on my birthday MK4 (assembled). Cool looking device, but having many issues with it. I don't think, that this is normal, so - please help me.
1) Every fourth print I'm getting an error: "Print fan error". Disconnecting and connecting back - helps. During the test - fan is always working. Just showing 0 RPM.
2) Every print every 5 minutes 0.10mm FAST DETAIL (Prusa PLA) - "STUCK FILAMENT DETECTED". Unload/load - printing going forward
3) Every second print - 0.20mm - same as above: "STUCK FILAMENT DETECTED"
4) Every third print 0.20mm - nozzle breaking first layer (it's just mowing so low, that it's pushing this layer from board). I'm cleaning board each time before/after print with "alkoholtupfer" 
5) Every random print - layers not gluing to each other, and all printing looking like "snots".

Tried all default parameters, edited temperatures - nothing helps.
If needed - can attach S/N.
Super sad, that used almost all filament to nothing 🙁

Hi, sorry you have been having these major problems, can I ask if you have been in touch with Prusa support? The snorting and layer adhesion issues could well be from damp filament

1) Print fan error - loose yellow pin. Re-jumper connector. Working good now.
2) Wet filament. On others - working OK
3) Same as 2
4) Nozzle was mounted to low
5) Same as 4

Is everything working now then? If so, that's really great news. 👍 Also don't forget to mark this thread as solved. 🙂
