Hello,
I have had a K8400 3D printer for 1 month and almost all of my printings ends like this … I have adjusted the tension of the belts and the parallelism of the bars but I can’t find a solution. I deeply regret my purchase.
Hey.
This is probably a problem with the motherboard’s cooling. Try putting on a fan
Ragards
thx for your help, I will add a fan to try.

Hello,
I had this problem a few years ago,
my solution was to direct the fan from the bottom to the motherboard with this: https://www.thingiverse.com/thing:1279678
to change and properly adjust all motor drivers and put small radiators on each,
Have ALWAYS a few spare parts,
The K8400 remains a superb printer after 4/5 years, almost daily use.

Hello Gloux,
The main reason for layer shifting (printhead jammming) is that the printhead shafts, and shafts are misaligned. Not the reason of cooling steppers or motherboard.
