I have a serious issue with my TAZ 5. Every single print fails right now. And the failures always look like on the pictures below.
The hobbed bolt eats away at the filament and no material comes out the nozzle anymore.
Here’s what I tried so far to fix the issue:
- completely cleaned the nozzle from any material
- made sure that the filament path is clear of any obstructions
- loosened/tightened the hobbed bolt to see if that makes a difference
- tried higher temperature settings
At first this issue only occured when there was a lot of retraction action but now it even occurs without retraction. Material also doesn’t make a difference. I mostly use PLA and colorfabb XT. Same problem on both.
What else can I try to fix this issue? I appreciate any ideas!
