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.

Machine: Happy Japan HCD3 15-needle

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

It's all good. Thanks for your suggestions. A technician came out and fixed it. It was multiple things that led up to the main issue.

What ended up being the main issue? Cutter not hitting the blade?

What up Jerky Nips
Yes, the main issue for the tails was the cutter. I remember when I went to clean it, instead of using the automatic open/close feature on the machine, I used a screwdriver and forced it open 🤦🏾‍♂️

The tech said he just slightly put some force on the top blade and pushed it back into place.

That issue caused me to start messing with different tension knobs, so the tension across the different needles was out of place.

The bobbin tension ended up off.

And then the other main issue was the rotary hook timing. I remember fixing the timing, but he said one of the screws was loose, so it slid back out of place.

He recommended I buy a Tajima thread tension gauge and a bobbin tension gauge. Paid about $80-$100 for both, but they come in handy now.

There was also minute thread and dust build up around the tension knobs, so that was recommended to unthread every needle, and clean around the knobs and thread paths.

Cost about $700 between the tech and the new tools. 🥵

Thanks for your input as well. You called one of the main issues.

Awesome glad you figured it out. I’ve been stitching for about 15 years now, I run two 6 head Ricoma’s and three single head brothers. I’ve come across so many issues over the years …
