I'm trying to print parts again after few months break and I keep having problems with infill.
The first layers are fine and the first infill layer as well.
Then the next layer (height 0.2mm) looks like underextruded or too fast and therefore not sticking to the previous one.
After a few layers i have lots off blobs on the inside.
The extrusion settings are fine when I print a calibration cube it's very precise 20.02mm X 20.015mm x 20.02mm
What settings should I change?
