I have been to my supplier to solve the problem with the blocked filament.
But after some hours of printen the same problem was back.
The filament is blocked in the PTE tube.
I have dismounted the extruder and removed the tube, which did not look to bad, see picture.
To me this seems a design problem of the printer.
What is the solution to this problem?
Go to a site like imgur.com/ upload the photo and after it’s finished copy the BBCode link in your post
Thank you. I have now added the picture to my post.
Try printing @190° for PLA and 225° for ABS.
I print PLA at 175 degrees. And season the head every once in a while.
