/** For some reason I cannot reply to the more newer posts: This is for @solarbird (who is from kbin so maybe that is an issue atm? idk **/
Thanks @solarbird!
This must be the case then. and somehow this filament has more issues. It threw me off guard because the others where printing still very good. Therefore I blamed the one thing that has changed: the filament brand.
Either way I have, per your recommendation, ordered some cleaning filament from esun. I will run that through and test again. I have ColorFabb coming this week to print the things for my client. And some other stuff in my backlog. Bit pressed for time, and cannot afford to have both printers out of commission. When that is out of the way I will test again for sure and cycle back here.
Again: thanks for the recommendation of the cleaning filament. This will help us to get the Ender back up again to. My dad has printed with wood filament and I do not think he was able to clean it very well.
I do not mind the disassembling things - in fact the opposite - but .. time!.. that is another issue atm.
