I have a problem with my k-8400.
When i press Auto Home, then goes the printhead to the right upper corner.
When he is there he make a lot off noise, and very loud.
When the noise is over, i can move the printhesad only to the left and back to the right.
He can not going down, it stuck.
I must to it by hand.
Problem 2
I make also a few prints with it, but everytime he make half pieces, there coming no more PLA filament.
I hope that you understand what i wrote, and that someone can help me, Plz.
Go into the Cura configuration and change the retraction to 4mm and the retraction speed to 110mm
Also if printing with PLA the temp should be 190C ABS=220C
Check the pulley that moves the filament make sure that the screw that hold it on the motor is tight and on the flat part of the shaft.
Don’t over tighten it and strip is
