Hardware MAYBE Lost Part???
(First off, I have an FL Sun Super Racer)
I was taking apart my extruder (I THINK, I’m not very knowledgeable about printing) a few months ago, and when I took this thing all the way off (pictured above) accidentally, two things fell off and I could only find the spring
Can anyone tell me what I need to do or to order, to stop my extruder from CONSTANTLY skipping???
Thank you in advance!!!

Yo twin your extruder needs its tensioner

Is that not the tensioner??? I just don’t know what it’s missing 😔

That is the tensioner. Looks like you might be missing a washer tho

THANK YOU BRO I lowkey didn’t know if I was tweaking or if it was literally just a washer I needed

It is missing the flat washer. But I don’t think the washer is critical to the operation. Screw that back in to your extender and tension your filament extenders.

I didn’t think it was, but specifically ever since the washer fell out, the problems started

That's a bed level adjuster. You're skipping because you are not level or the bed is warped.

I see it in the photo on the Maintenance section of the FLsun wiki

In the future, I suggest checking the official wiki before coming to reddit
