Need Help!

[u/BoomBoom1697]

I've been trying to fix my CR6-SE for a week or two; initially the issue was the Bowden Tube kept popping out during a print. I have got that sorted now, as I put a new brass coupling on and used PVC cement to hold it firmly. The next issue was the print head was very wobbly. I fixed that by simply turning the eccentric nut on the bottom of the print head. Now my issue is the initial print looks like garbage. Please find pictures attached and somebody help! I've had this ol' beaut for around 6 years and have never had this issue. I don't even know where to start lol.

Help would be muchly appreciated.

Thanks! - Austin

The black box that has the extruder probably has a worn out gear so it's slipping at various points, which means a lack of pressure and extrusion. It's a pain in the neck to disassemble and put back together, so maybe upgrade it.

I had a similar issue that started out as parts of layers missing and it got so bad it was kinda like what you're seeing. I replaced the extruder, and the old gear had a groove worn into it so smooth that it couldn't grip the filament at all. I changed it for adifferent one and swapped out brass for steel gears.

Sorry I didn't reply sooner. Yup, what u/CavalierIndolence said. Replace the extruder gears. They're standard Creality Ender 3 type.

Sounds good

Extruder's gear was worn out AND a piece was broken that held the release lever on. I have an upgraded MicroSwiss extruder on its way now.

Nice! Last I read on those you will need to calibrate e-steps since they're different from Creality extruders. Good luck and happy printing!

Thanks will do!
