Thanks guys, it sounds like it’s probably ok then. I don’t really need it to do those long stitches, I just started wondering if there was something wrong with it, since I had read about bigger stitches on other machines.

Yeah, sorry for the small picture of the 45k21 courtney but you can see it says max stitch length 1/4 "

My 45k25 seems to stitch pretty well, but when I set it to the longer stitches it immediately leaves loops and knots on the underside. I’ve tightened the top tension until it’s way too tight and still does it. I’ve played with both top and bottom tensions. Tried a 25 needle 277 thread. When I move it back to shorter stitch the loops go away. 
 

…Also!…this is my post, “courtney” and I’ve been locked out, forgot password for a really long time, tried so many times to reset, and contact admin, but never get a response/email…can someone help me please?

Post pictures of your threaded machine please. When you have tightened the top tension and you still have loops on the bottom I would assume too much bottom thread tension or maybe a too weak top tension spring. But I only can guess w/o knowing your machine.

You would think that’s it, but the bottom tension is very light, and the top tension is so tight I’m breaking needles pulling thread through by hand..,only as a test, I’ve adjusted it all different ways.

Is there any reason though that everything would change only at the longer stitch length though? Cuz it is fine at shorter spi

I can't do anything about you forgotten password, but I can offer a suggestion about the change in tension with longer stitches.

In effect, with all things being well balanced at short stitch lengths, when you make much longer stitches you draw more top thread than bottom thread and the top tension decreases somewhat. When this happens to me, if I can't reduce the bobbin tension any more, I move up one needle size. I also increase the throw of the check spring so the top thread is held taut longer.

Thank you @Wizcrafts & @Constabulary,

I was thinking a bigger needle might do it, but 25 was as big as I had w/ 277, I did put some thin thread on top but it broke..

the check spring, I’ve never adjusted, was thinking maybe that would help, cuz I have that automatic thread regulator tab thing, that says it’s for the purpose of adjusting to different thicknesses, but I don’t really understand. I’ll go fool with it a little more

Well, I don’t think adjusting the check spring did much, but I put 69 in the bobbin and top with a 25 needle and light tension through 9 oz. Veg and it worked fine, even with that tiny thread the big holes really weren’t that noticeable. Maybe. A 28 needle w/ 277?

I use a #18 needle with v69 thread and a #25 with v277 thread. Your needle is the right size for 277. Something else is wrong. That something is either causing the top thread to lose tension on the upstroke, or the bottom thread is hanging up as the top thread goes around the shuttle and tries to pull it up. Watch the thread go around the shuttle and see if the bobbin thread is getting caught on the feed dog or its mechanism, or the hook itself on the way up.

@Wizcrafts, ok, I’ll see if I can make a video, and do some tests
