Prusament PETG Matte Black
I have a roll of PETG Matte Black here. I read it can be a bit tricky to print, but I had no idea that it is that tricky...
While "Signal White" and "Urban Gray" print without any problems with the Prusament profile, I cannot get Matte Black to work. I started by increasing the retraction length up to 5mm, but that would not change anything. Then I reduced the temperature down to 210°C - at which I got reasonable results without excessive stringing, but the first layer quality degraded massivly.
I noticed that the nozzle gets dirty very quickly, i.e., filament attaches to all sides of the nozzle and I had to remove rather large clumps of filament after the print.
Does anyone has settings that give a reasonable print quality or could give some advise what other settings than temperature and retraction length I could test?

Did you dry the filament?

RE: Prusament PETG Matte Black
No, not yet. It has been subjected to the room the same amount as the others - the Signal White was even open for weeks and prints very well - thus I did not suspect that moisture is the problem.
I can try that next week. Is the Matte Black more moisture sensitive than the others?

I haven't tested Matte Black, but drying ALWAYS makes things better, with zero downside. Whenever I go to print, the filament spool goes into the dryer for a few hours before, and I live in the desert. Commercial molders always dry their material. Various materials and colors are worse than others, but since I always dry, I don't have a list of which ones. A heated dryer is needed. A dry box or desiccant bag does not cut it.
