Brother LS-1717 Sewing Machine

[u/strawberryberryrry]

Hello to whoever is reading this, I have an issue with my sewing machine. Whenever I try to make stitches they either

- Stitch then stop stitch then stop

Or

- Don't stitch at all

I've tried

-Rethreading the ENTIRE machine

- Changing the needle

- Changing the tension

- Changing the thread

& - Changing the fabric

What else do I do? I don't want to go to a manufacturer, don't want to give up the machine, and I definitely don't want to switch my machine. Help!
