As i seem to have fixed my biggest problem which was caused by retraction length there appears to be one that is totally filament related. The Filament is eSun PETG (transparent blue). That stuff basically prints quite well as long as the layer or “island” is big enough. I’m only using 2,5mm retraction in this print and you can easily spot the problem. It appears in the small posts of 3DBenchys house and on the chimney. Not only that extrusion is totally unreliable it also seems to overextruder after a short while. I’m not sure where this may come from and havent seen this before. I’ve double checked the filament transport in the Feeder and that doesn’t show any problems.
The Filament generally seems to be more on the problematic side. It appears totally creamy when it comes out (no matter if at 245°C or 260°C - tried everything in between in 5°C steps) and tends to grease up. But that extrusion problem definitely makes it unusable for smaller parts.
Does anyone yet have seen such a thing?
