Poor quality when printing slopes. I can hear a significant grinding noise when printing this particular model, blobs showing up, and unevenly spread filament. I increased the solid layers from 2 originally (photo with holes in the model) to 6 after but the result was still poor (poor finish photos). It seems that the printer is not moving the bed apropriate height for some reasons. Any suggestions what is happening here?
Looks like under extrusion to me. When did you last try to clean your nozzle?

The thing is that bottom layers are printed perfectly… Underextrusion would be impacting whole print, right?
Looks like you’re having trouble down low, too… Speed has a lot to do with extrusion so it’s not too unusual to see varied levels of “impact” from a partial clog in different areas because print speed varies.
It can’t hurt to clean the nozzle. Heat it up and run the poker through from the business end and you don’t even have to take anything apart (you do have to be careful not to burn your fingers). A full clog may not be cleared by this, but a partial clog would be.
How many hours on this nozzle?

Around 70H. I was cleaning it 2 days ago, and i dont this is the problem here
The printer came with a spare 0.4mm nozzle. It literally takes like 5 minutes to swap (10 minutes if it’s your first time because one connector has some silicone goop to hold it in place, and you need to carefully peel that off to avoid damage to the mating connector). If it doesn’t make a difference, then the old nozzle becomes your spare, you don’t have to swap it back.
I don’t see anything to suggest the Z axis is misbehaving. Just looks like bad extrusion to me. Since it’s happening on more than one filament, that strongly suggests the nozzle as the common denominator.

Hi.
Slopes are always tricky.
But I can see blobs in “easy” regions.
The nozzle can be the cause.
Another possibility is the filament or printing settings.
To try to help you:
-
What filament are you using? From the picture, it seems to have fibres, such as wood. Is it dry? - note: after three months of 24-by-seven printing, I attribute to wet filament the causes of my few printing issues. Since day one, I have felt that BL printers are pretty strict regarding filament quality, as the same “wet” filament works flawlessly in my S1Pro.
-
What printing settings are you using? Is the slicer default profile? If not, did you carry out a proper calibration? - if the filament and nozzle are in good condition, I would guess that part of the top surface’s low-quality results from ironing.

Sorry to bother you, but did you resolve this issue? I’m having what looks like an identical issue and am wondering how to resolve it! Many thanks!
Hey,
Yes I was able to resolve it. Mainly by changing the top layer count and infill to gyroid. That completely resolved the issue.
Hope this helps
