Help - Industrial machine

I'm using textured poly thread (similar to wooly nylon) doing zig-zag stitches on a Singer 20U73. It's been working perfectly, then the thread started breaking. I noticed the thread was dropping down and hanging in a foam pad under the cone. Since it wsa worn and torn I threw it out so there's nothing under the cone now. It still breaks. I've rethreaded, changed the needle, made sure there's no thread obstruction or hangup, oiled the hook, tried on different fabrics and it still breaks and the few stitches it does are uneven with blobs of the polyester fiber on the bobbin side. Can anyone suggest anything. Many thanks.

Have you tried feeding the thread up in the air to an eyelet, and then back down to the rest of the threading for the machine? Sometimes that helps. However, my first thought when having problems with any odd thread is to try the same stitching with a spool of known-to-be-good thread. I'd also check along the thread path for snags and nicks and other nasties that might be slicing the thread.

Is there some lint caught between the tension discs?

Many thanks for your suggestions. I checked the thread path (I'm using a thread tree) and although a snag from the bottom of the cone seemed to start the prob, that wasn't happening. I rerouted the thread through an additional eyelet on the machine (intended for bobbin winding), cleaned the tension disks, replaced the needle (again -- this time with a size larger) and rethreaded about a thousand times. Now it's working again. I have no idea why. I also loosened the tension on the bobbin case. it had gotten tighter than it was supposed to be for some unknown reason. I'm not sure I believe sewing machines can actually sew anyway. Just another mystery in a long chain of them...
