Catherine50 Posted February 4, 2011 Report Share Posted February 4, 2011 I posted about this yesterday, and have since tried many things to fix the problem. I have checked, and redone the timing. The bobbin area is clean, and the bobbin is in the correct way. It only seems to happen when going straight across, from left to right, when standing at the front of the machine. It happens when I slow down, or stop, but not when going a consistent speed. I've been using the baptist fan pattern, and it is happening at the bottoms, when changing direction. The stitch regulator is on when it happens. When going at speed, or on curves, the tension is good. The thread in these pictures is so fine in the bobbin, and bottom line in the top. I have a stockinette over the cone of thread. It will do the same thing with other threads as well. It sounds like the bobbin assembly is trying to take an extra stitch before starting to move again. The top threads, where this happens, are very loose. Does any one have any ideas of what is wrong? Do I need a new stitch regulator? I have a customer quilt that I have to do that involves a lot of straight line quilting between squares, and there is no way I can do it with this going on. To add to the frustration, although I have resized the picture, I can't seem to get it to upload. I keep getting the massage that the file is too big. However, I have a picture of the backing and the tthread tangles on my blog, if you go there. Please help!!! Link to comment Share on other sites More sharing options...
witha'K'quilting Posted February 4, 2011 Report Share Posted February 4, 2011 I feel your pain. I have looked at the picture...amd honestly have no advice to offer. The so fine thread looks really thin...almost like it is shredding. Does it appear to be doing so? Link to comment Share on other sites More sharing options...
Catherine50 Posted February 5, 2011 Author Report Share Posted February 5, 2011 The thread that looks shredded is the bottom line that is being pulled from the front to the back of the quilt, and yes, it is shredded. The same thing happens when using Rainbows, while with King Tut, it just makes a big knot. Link to comment Share on other sites More sharing options...
witha'K'quilting Posted February 5, 2011 Report Share Posted February 5, 2011 I misread which thread was on top..sorry. Is the bottomline catching on something either in the thread path...or as it is traveling around the bobbin area to pick up the bobbin thread? I wonder if there could be lint or thread caught somewhere that is causing the problem. I find it hard to believe it could be a stitch regulator problem.

Catherine50 Posted February 5, 2011 Author Report Share Posted February 5, 2011 I have cleaned everything, and checked for anything that could be catching on it. If it isn't the stitch regulator, is this the kind of thing that happens with burrs on the hook? Link to comment Share on other sites More sharing options...
witha'K'quilting Posted February 5, 2011 Report Share Posted February 5, 2011 Don't know...a burr could cause it to be snagged however..so possibly. Link to comment Share on other sites More sharing options...
Quilting Heidi Posted February 5, 2011 Report Share Posted February 5, 2011 I've never seen that either but wondering it if it is the needle flex causing the problem. Didy ou try a bigger needle? Link to comment Share on other sites More sharing options...
Catherine50 Posted February 5, 2011 Author Report Share Posted February 5, 2011 I have tried a new needle, but not a bigger one. I'll have to see if I have one. At this point, I'm willing to try anything. Although, I've always used this size needle, and this is a relatively new problem. Link to comment Share on other sites More sharing options...
newmillie2010 Posted February 5, 2011 Report Share Posted February 5, 2011 try a new bobbin case. just my thought. and run a straight pin under the tension 'finger' on your 'old' bobbin case. i found a bit of lint and stuff under mine last week - got the hint somewhere on here i'm sure.

Judi Posted February 5, 2011 Report Share Posted February 5, 2011 I have found with some types of batting (even more so on a flannel quilt) that lint build-up will happen in the bobbin finger with every row of quilting. Instead of a pin though - I use the pick end of a plastic floss pick. I always have these in my cleaning bin of my tool box. Come in handy!! :cool: Hope you have figured out your problem Cathy - is it better?? Link to comment Share on other sites More sharing options...
Catherine50 Posted February 5, 2011 Author Report Share Posted February 5, 2011 I haven't figured it out, yet. I'm going to try, now that it daylight and I can see better, to see if can move the machine and look at the bobbin area while it is moving, to see if I can actually see what is happening. I have check the bobbin case, and cleaned under the finger. :mad: Link to comment Share on other sites More sharing options...
witha'K'quilting Posted February 5, 2011 Report Share Posted February 5, 2011 I sure hope you can get resolve soon. did you notice any burrs? Link to comment Share on other sites More sharing options...
ffq-lar Posted February 5, 2011 Report Share Posted February 5, 2011 So sorry for your problems. Since it happens as you slow down for a direction change, perhaps your bobbin is spinning instead of stopping, which throws out extra bottom thread and may snag the top as well. Check the backlash spring and pry the fingers out a bit more if they are flat. I can't think of what else is causing this. But the knots with the King Tut are caused by the same thing--over-spin of the bobbin. It's just that the Tut is so much thicker, you won't get a nest, just a knot. Good luck and I hope your problem is resolved soon. Link to comment Share on other sites More sharing options...
Catherine50 Posted February 5, 2011 Author Report Share Posted February 5, 2011 I just spent some time under the machine, watching as the thread goes around the bobbin assembly. I have discovered that the top thread is actually getting caught, and dragged in behind the bobbin, in between the stationary silver part, and the black part of the bobbin assembly, where it then, of course, breaks, but there is enough thread left in the needle to keep sewing, and leaves the mess on the back. That is why it is worse with the fine thread, than the thicker thread, which gets caught and forms a lump, but won't break, because it won't actually get dragged to the back. Diagnosis, I think I need a new hook assembly. Link to comment Share on other sites More sharing options...
jeri Posted February 5, 2011 Report Share Posted February 5, 2011 maybe not a new hook assembly but you may have to do some adjusting of the hook collar or the mag collar. I would check those before ordering a new hook assembly. If the mag collar is off the thread will tangle around the back of the hook assembly. From what you said sound like this may be the issue. Would be happy to help you with that if you need some help. The directions to adjust that are not in the manual Link to comment Share on other sites More sharing options...
Catherine50 Posted February 5, 2011 Author Report Share Posted February 5, 2011 If you could send me the instructions to that, it would be great. Especially since I don't know what the "mag collar" is. Link to comment Share on other sites More sharing options...
nora123 Posted February 5, 2011 Report Share Posted February 5, 2011 What kind of thread are you using?. I had this happen with glide thread. It is so slick it flew off the cone so I used a thread net and that helped a lot. Also make sure you are not winding to much thread on your bobbin that can do this too. I hope you are able to get this solved. There is nothing worse than having a customer quilt on and your machine goes crazy. Blessings... Link to comment Share on other sites More sharing options...
Catherine50 Posted February 5, 2011 Author Report Share Posted February 5, 2011 I'm using bottom line in the top, (I know, I'm backwards, LOL), and So fine in the bobbin. It also does the same thing with Rainbows in the top. Jeri said something about a hook collar, or mag collar being the problem, and needing adjusting. I'm hoping he will send me the instructions on how to fix this. Either that, or I'll have to call on Monday. Link to comment Share on other sites More sharing options...
jeri Posted February 5, 2011 Report Share Posted February 5, 2011 What year is your machine? There are 2 sets of instructions, one is for 2008 and newer. I'll see if I can get them to scan in and e-mail it to you. I'll also need your e-mail address. If you want mine it's justquilting@att.net Link to comment Share on other sites More sharing options...
Catherine50 Posted February 5, 2011 Author Report Share Posted February 5, 2011 It is a 2005. My email address is caleeshepherd@yahoo.com Thank you for your help. I really hope this works. Link to comment Share on other sites More sharing options...
jeri Posted February 5, 2011 Report Share Posted February 5, 2011 the instructions have been e-mailed to you. Wish that I had the photo we took of my friend's thread mess to see if it matches yours. Was on her camera. Link to comment Share on other sites More sharing options...
Catherine50 Posted February 5, 2011 Author Report Share Posted February 5, 2011 If you need to see the mess of thread on the back of the quilt, there is a picture of it on my blog, the address is down in my signature line. The diagnosis of the mag collar being the problem seems to be correct. The hook is stopping quite far off to the right of centre. Thank you for your help.

jeri Posted February 6, 2011 Report Share Posted February 6, 2011 Hope it is the solution. The photo would have been how it was tangeled in the hook assembly, I'd already checked your blog. Love your quilting bBTW. Glad to try to help, that's one of the great things about this forum. You can often get help when APQS isn't open.

Catherine50 Posted February 6, 2011 Author Report Share Posted February 6, 2011 Jeri, can you please resend the second page of the instructions on how to fix this. I have up to the part of taking off the motor cover. The other page won't open. Link to comment Share on other sites More sharing options...
