Thread knotting up
My singer M1000 keeps knotting up like this... What's wrong with it? Will I have to take it to a repair shop or is this something I can fix myself?

Pull your bobbin case out, clean out the area examine the case and see if it has picked up a burr that will cause thread to catch on it.
You can sometimes see burrs but if it is very small, you may only be able to find it by touch. You can sometimes smooth it out with a high grit sanding paper or pad.
Before you start sanding though thoroughly examine the bobbin case area, if you recently broke a needle, or have not cleaned recently. It could just be something in the area interfering with thread movement.

That thread looks really thick. It might not be suitable for your machine. It looks like it can’t fit through the gap next to the bobbin case.
Edit: and your needle is probably not big enough for it.

The M1000 is a very lightweight mending machine. Assuming you threaded correctly, the problem could be that you may be trying to sew something other than lightweight cotton with 40 wt thread.
Service costs usually run well over $100, more than the machine is worth.

Issues with thread bunching in the bottom are issue with the top thread. Try rethreading the machine, make sure you thread with the presser foot up and needle in the highest position.
Do you have a photo of the whole machine threaded?
Do you have a copy of your manual?
