Ideas about bulging corners on top ~5mm? (lemmy.world)

It’s not top thickness, that’s only 3 layers and the bulge is on more layers than that.

Printed with PLA, 4 perimeters, 15% gyroid, but no infill makes difference, i don’t think this is about shell thickness.

Retraction is good, there is no oozing on retract moves and no stringing on the printed parts.

Otherwise the prints come out okay so i’m a bit stuck with this one!

You can see the bulging in all three edges on the picture, about 3-4mm from top to bottom, then a few ok layers, then again a few layers with bulges on corners.

Slicer is Prusa if that’s relevant.

Any ideas are welcome!

The correct answer for this is linear advance needs tuning. Google how to do that.

Other than that, getting a direct drive extruder like the TBG Lite will help a lot as well.

Does this imply too high or too low of a linear advance value?
