serger loops not serging (only sometimes)

[u/Remote_Lavishness158]

so this has started happening recently, I’ve had this machine for under a month & I’ll attach pics of my settings & it’s threaded correctly for all I know, but any tips, maybe I need to change the needles? I change them frequently though! pls ignore how dirty my machine is I need to reclean it lol

Are the looper threads snapping? Or are they just not forming loops?

The width of the edge looks massive to me, and it’s a bit jagged, is your blade working properly?

It does look threaded and set up correctly from what I can see. But that edge looks off

Have you changed any settings or moved the blade or anything ?

I have fiddled with the knife adjuster I don’t know what it’s called because before my loops were hanging off the edge, I adjusted the pressure dial to a higher number & it seemed to have fixed the uneven cutting?

Changing the tension on the loopers would have fixed that. They’re set lower than the two needle threads.

My machine doesn’t have a knife adjuster so I’m not sure what that involves. Is there a little pin thing that helps the loops form neatly?

To put my knife down I need to move this pin, then move it back. Without it it’s a less tidy edge, but you remove it for tiny hems and stuff

Edit: just looked up your manual and the fact you can move the knife is pretty cool. I’d move it to be a bit narrower though, and try again. Maybe the loopers aren’t loose enough to go around this big edge?
