PAHT-CF cannot get dry anymore?

[vladimir.minkov]

did you do factory reset ? and check flow and PA calibrations
EDIT:
@djeZo888 if interested read this post , if you dried your filament for more than 20h that is not your problem , for some filaments it takes 20-30h , i use silica color change probe which put together inside the roll and checking the color that is back to normal , but again don’t think this is your problem

Irritating under-extrusion problem after FW update? Try this

I had some showing the problem at its worst, but deleted them (due to icloud storage space issues). However, you can see some of the issues here. The box lid was printed face-down, and should be completely smooth, but under-extrusion was leaving lines that you can see criss-crossing the surface. People might have said that it was fist layer issues, but the problem repeated throughout the part and was particularly pronounced on the final layer (which you can’t see here). [IMG_0692]
