I have the Jenome 6500 Memory Craft.
It started to have issues with the bobbin popping up and or making noise when sewing.
I have attached a video without thread in it and it still does this.
Things I have done.
1. Validated that bobbin is in correctly.
2. Used a new bobbin.
3. Reused the current bobbin, but rethreaded.
4. Adjusted the top tension
5. Taken apart and cleaned.
6. Repeated steps above.
Please advise, thank you so very much.
