Poor stitch quality

13 posts in this topic

I've been fighting with my Lenni for several days - well, weeks actually. I'll be quilting along and every 30-60 seconds it loops up the top thread. The thread doesn't get pulled tightly. Occasionally it's just a single stitch, other times it's several stitches in a row, which really creates havoc. And when it's not looping up random stitches, it's just breaking the thread. I mainly use glide on top and magnaglide bobbins. I've also tried So Fine and Magnifico by superior. It's happened on several different quilts over the last week. I'm in a very dry climate, and I've started using sewers aid, which seems to help a bit with thread breakage. But this poor stitch quality is driving me bonkers! Please offer suggestions!

Sounds like you have used different cones of thread and bobbins so it probably isn't one of those.  Double check the thread path again....I once thought I had checked that several times until I took out the manual and really checked it....then found two things that I changed and it helped....one was the first thread guide over the cone was not in the right position so that was adjusted and the big thing was that the thread had somehow gotten out of the thread guide right by the tension adjustment....that probable was the biggest thing....check the action of the spring in the disc tension too...you also could have a burr somewhere where the thread is catching a bit...that could be anywhere along the thread path....or a piece of lint could be caught somewhere...other folks with more experience than me will chime in I am sure....Lin

Carrie:  I think your problem is with your take-up spring.  It's improperly adjusted, or doesn't have enough tension to pull the stitch tight.  First make sure it is moving freely, and at rest, it's at about the "11 o'clock" position.  If those two are OK, you'll need to increase the tension on the spring.  That involves removing the tension assembly from the machine, loosening the screw that clamps the main tension rod, rotating the rod to increase the tension on the spring, tightening the clamping screw, and then putting the tension assembly back in the machine.  Oh, by the way, before you start, check to make sure the spring isn't damaged.  Good luck.  Jim

Hi, everyone! Reporting back. I was hopeful that the wd40 bath in the bobbin area had fixed my problem. It did indeed improve it, but my problems have been creeping back up and no amount of wd40ing can make it go away now. Jim, I'd like to try your idea. Are there any videos or illustrations available for clueless people like me? I have a feeling you are more experienced than me. Like, when you said to make sure the spring isn't damaged... I don't even know how to tell whether or not it's damaged! Ha!

My biggest symptom right now is usually a thread break that actually fixes itself after a few stitches, before I can actually even get stopped. But this time( I will try to post a photo), it didn't quite break completely. It looped up the top thread for several stitches (where I'm pointing), then continued on normally. And you can look above where I'm pointing to see earlier stitches. When these earlier stitches were made, they were perfect, but when the break/loop-up happened it snapped the top thread tight, like a slingshot, and distorted those previous stitches.post-64629-0-18496500-1450510741_thumb.jpeg

When I have this problem, it is because I have missed the shepherd hook in my thread path.

Interesting on how this one got to the front of the line from 2 years ago.  There are many reason why this happens.  The check spring is out of wack or bad, bur on the hook or on one of the thread guilds or even a bad needle.  There's also a bad spool of thread and sometimes it's just a simple fix of putting a piece of batten above the spool in the thread guild.  And of course it could be the so called " Shepards hook" after the check spring, but normally when that is skipped you will get bad looping on the back.  Anyways, take your pick and carefully inspect your machine for indiscretions.   Zeke
