Help needed - print quality issue
-
I finished my BLV mgn Cube build but unfortunately I still have some quality issues. Trying to fix that for days know but cannot figure out the cause. Any help from you experienced guys are appreciated!
Did all the tuning stuff (PID, steps, pressure advance, equal belt tension, etc.) but corners are still a mess. Any ideas what can cause this?
-
Post your settings. config.g and your slicer settings.
It looks like some corner overshoot or blobbing.
The cube also looks a bit over heated. Try printing two cubes on either side of the bed.

@MartinNYHC said in Help needed - print quality issue:
extruderExtraRestartDistance,0.05
Perhaps too much extra restart?
I think it's also a good idea to have at least 2 slicers configured and ready to go so you can compare results. That can really help narrow down if it's a machine issue or a slicing issue.

Thanks.
I used this extruder and hotend for some months on another printer and 0.05 restart was perfect. But I'll doube check it and also try a different slicer.
Currently printing two cubes at the side of the bed.

Your pressure advance seems high for a retraction distance of 0.75

I always used 1mm retraction and did a PA test. Result can be found here. I lowered the retraction this morning to check if that changes anything.
-
I just recognized that the "bad corner" is always the one where the layer starts.
-
As already mentioned it is always the corner where the layer starts that is "bad".
I'm totally lost. Any ideas please?
-
And another pressurte advance test...
-
Another Benchy...
-
what extruder do you have?
-
Bondtech, Mosquito Magnum with approx. 20mm PTFE tube between.
-
can you try to adjust to bondtech tension to a lot higher and try that?
-

No difference. Still the corner where the layer starts
-
you did not yet say if the print with another slicer was better

Oh sorry....no it's the same result.
-
and did you print one without pressure advance?
-
Yes, but in the meantine I changed some settings. Will do another print without PA.
I fear the worst that it is a mechanical issue. When I compare the prints the "bad corner" has the same pattern:
-
Without pressure advance it looks better but I still have the scars where the layer starts. I don't have an idea at all what to do next. Any more ideas from you experienced guys are very appreciated!
