Hello everyone!
I have been experiencing a persistent issue for quite some time now. Whenever I print larger designs, the quality significantly deteriorates the higher it is printed. As you can observe in the picture, the top part appears distorted and it seems like the printhead fails to align properly with the underlying layers. Interestingly, when I print a single item, the quality is perfectly fine.
I have already examined and ensured proper tension in all the belts. I have also checked the hotend and cooling system, which are functioning correctly. Additionally, the spindles appear to be in good condition as well.
Any help is appreciated!
No change with rotation is weird. Do you mean the artifacts are on the same side relative to the parts, or relative to the printer?
Is this a modified MK3S/S+? I see the extra screen, but what about the PTFE tube, is that from an MMU?
If the inertia is from the relatively fast movements between parts, no. Printing moves are more gentle than movement-only moves.
Edit: It may be worth trying to print at 50% speed (knob anti-clockwise during printing) just to see if that changes anything.
Rotating the part on the printbed results in the same artifacts relative to the printer. always the backside the most. Hence i thought belts being the culprit before.
It is a slightly modified MK3S With MMU2S. It has a display with octoprint. I rule out octoprint being the culprit as printing from the SD card directly results in the same. The entire print assembly is fully stock.
I will give printing it at 50% a try to see if it improves things. thanks for the suggestion!
