Crazy stitching

[Clintock]

@Bugstruckthat spring with the loop holding the thread coming off check spring does rest on the stainless seat. I tried to wrap the thread around the upper disc tensioner but I don't see how it can be done with the tension release hits it when you raise our foot. It puts my thread at an angle that it'll glide over the end of that "disc splitter"? Changed out bobbin again. So I'm on the 4th one. Still the same. 

 

 

Is there a way to reset all tensions on machine and start over? There has to be. But where would one start?

Try this. Pull the top thread out of the second hole in the top post and just run it through one hole. Then loosen the screw on the thread loop in front of the tension disks and push it as far down as it can go, then lock it in place. The rational is that by lowering the thread guide it will feed the disks from a greater downward angle, better securing the thread inside the disks.

Pay attention to whether the disk separator is interfering with the full closure until you lift the feet. It should not push them open at all until you lift them, nor should the point hit the thread as it feeds down to the roller disk.

Resetting the tensions means remembering how tight they were when you got the machine. Just set the bobbin tension for a moderate pull (not too tight, nor too loose), then balance the knot position with the upper tension nut. You can play with the bottom roller tension to see if it makes any difference. But, to have any tensioning affect, it needs at least 1.5 full turns before it exits over the pin. Anything less and the thread will just slide around the roller disk.

@Wizcrafts tried just going through one hole in top post. Changed the angle of the loop you were talking about. The loop bottoms out on the disc separator. It did move about a 32nd. Had to completely remove top discs and spring to access screw. Reinstalled and it's better. In a run of about 4 inches I had that crazy knot only twice. 

I do have a wrap anna half around the main tensioner before overlapping side post. You can see in the pic.

UPDATE:

found a piece of thread between what looks like a race behind the bobbin. So far so good except on corners but that's prolly me. Any advice on what to do to correct that would be great

THANKS TO ALL THAT GAVE INFO ON THE MATTER!! I really do appreciate the time you took to help me.

Ah yes, the old thread stub trick.

I dont have this machine but in the UK they sell a spring tension gauge designed for sewing machines, so you can measure the tension on pulling out from the bobbin as well as the top thread, its a handy way to make a list of different tensions with different threads

Now that sounds like a good idea. I'll check out the ebay and get back if I find something.

And here's a video demo of similar

The reason showing on embroidery machine is with up to 15 seperate needle assemblies on a single machine tensions are a major problem, and some stitch designs may use 15 colours and 30-50 thousand stitches causing a lot of lost time if one colour goes wrong towards the end of a run and not notices for a short time

@chrisash Thanks!! Not a bad idea to have  one. Make sure you get the same tension on certain projects. Would hate to have to adjust that many threads

@RockyAussie Appreciate ya looking that up and giving us links.
