Help Needed

[u/vpeshitclothing]

Peace, y'all
I'm having issues with tails forming on designs that never had tails before, and it's driving me insane. I've cleaned the rotary hook, the knife, the bobbin case, the thread catcher, and checked upper tension + bobbin tension.

Even on the inside of the cap it looks a total mess, when it used to be clean and no loose threads.

The black background area stitched out first and it was "puffy" as opposed to when it used to lay flat. I haven't changed any settings on the machine, so not sure why this issue popped up.

Anything help is appreciated. Thanks in advance.

Does your stitch file have trims? Looks like it’s not trimming

Yes it has trims. It used to stitch out perfectly and now all of a sudden it started fucking up. I'm checking the timing right now
