  • Okay my new guess is moisture in the filament causing inconsistent extrusion, leading to the bubble on the surface. And also causing over extrusion.

    For the walls, your picture is a bit too blurry/low res to really see, but I get the vibe of over extrusion with the small part that’s sticking up in the center of the perimeters in the lower right. Also the top of the anchors for the supports looked over extruded, with plastic kinda curling up at the top.

    Your new print is now definitely under extruded with those gaps on the top surface.

    I think flow rate is not the culprit here. Your bridges on the first print are also extremely suspicious. They should be solid lines, not the blobs you’re getting. Something is wrong with the flow of filament out of the nozzle. Could be moisture or temperature or issues with the extruder. It’s hard to tell.


  • Your non-infill regions also look very over extruded. I’d try printing 20mm cubes with a variety of flow rates and see what happens. If you’re using their profile, is it possible that the filament you have is larger than specified?

    edit: looking a bit more, things seem really blobby too. Something is not right. Is it possible the temp is wrong for this filament? What is it?
