First layer adhesion issues since installation of MMU3
Since I installed my MMU I keep having massive issues with first layer adhesion. After the primary installation I could not get any print to stick. Fortunately I could resolve the issue by installing a new nozzle (although the old on was only a few weeks old an not worn out).
After a few successful prints, the problem reoccurred and I keep having failed prints or masive warps.
I tried smooth and satin plate and printed with different types of PLA (most of it fresh Prusament PLA) and have now real clue, why it occurs. I do definately do not have any extrusion problems (the cleaning stripe on the edge of the printbed sticks perfectly).
My idea is, that it has somethin to do with the nozzle or its insertion into the extruder. Anybody else had those problems or any tipps for resolving?
