I just recieved a roll of eSUN black PLA+ and I have found out it has moisture damage after using it for 2 days. I was previously using a roll of eSUN orange PLA+ and it worked really well. So I ran a stringing test just to make sure the settings were right for the black roll and the result was terrible. So I spent a full day messing with slicer settings as moisture damage was last on my list for the issue since the roll was brand new. But with no improvement I decided to dry out a sample of filament just to try and this was the result.
Left is filament straight from the roll, middle is dried out filament and orange as a control. So now I know the problem is this normal for eSUN filaments? Should I dry out filaments as soon as I take them out of the box? I didn't have this issue with my orange roll.
