Hey all, so this is the biggest thing I’ve tried to print. I’m using PETG. I’m getting a lot of repetitive bands of underextrusion that seem to stack up and get worse as the print progresses.
What do you think is causing this? Is this just an inherent thing in the way an Ender 3 works by moving the bed?
You must log in or register to comment.
The typical guesses in a case like this:
- Bed leveling
- Crappy extruder that needs to be tightened or better replaced (I can really recommend the TBG Lite, amazing extruder)
- Temperature too low
- Crappy or wet filament (wet doesn’t apply to PLA, but PETG prints super bad when wet)
Or all of the above.
I recently had an issue that caused similar issues. Ended up being a bad wheel on the Z axis. Wheel was damaged and the carriage would move up and down as the Z axis traversed causing that stripped pattern.
Good luck!
I second “not hot enough”. The PETG lists it’s ideal temp as 230 on the reel, but it seems to need closer to 245-250 or I get similar.
Er, the PETG I have, I mean
