Baby Lock thread cutter button
 

I'm having a tension issue with starting a new seam, after using the thread cutter button on a (new) Presto 2 machine. I get a small thread nest (under the fabric) at the beginning, and I can see the lost tension as the thread sort of billows out above the needle bar thread guide for a few stitches before it settles down. It doesn't happen if I don't use the cutter button. Has anyone experienced this? Am I doing something wrong?

I've been told by a local dealer that all machines will do this if the cutter is used, and the only way to avoid it is to either chain piece or leave a long thread to hold when you begin the new seam. I have the same issue.

I have a Babylock Jane with thread cutter it never acts up. I try to always start sewing where the needle can go into the fabric.

I don't use the thread cutter on my BabyLock for this reason. I'd rather use scissors to cut the thread. That way I have enough thread to hold onto for a new seam.

I have a Babylock and like Jingle, I don't have any problem with the thread cutter. Be sure you use the cutter before you go off the fabric. My manual said to do it that way. I find I can be one stitch off the fabric without problem. I've never tried any further off the fabric but could see how it might cause a birds nest.

It sounds to me like the thread cutter leaves too short a thread, and that's why this happens. On some machines the length can be adjusted by the dealer, I don't know if this is true for your machine.
I always start by pulling my bottom thread up to the top, and then putting the tails under the presser foot, directing them to the back of my work. I find this stops any thread messes/tangles on the back of my work when starting up.

If I'm understanding you correctly, the first "down" of the needle is right into the fabric, not before the fabric, which is what I've been doing. It sort of works... I don't get a nest, so much as a small loop of thread.

Have you done all the updates for your machine? Many times the updates take care of the issue. These are free downloads from the BL web site and specific to your machine. These are not "upgrades" which have fees. It is easy to send to the usb and then load into machine. Just follow the steps as directed in specific order.

Does your machine have preference pages where you can change settings?

There should be no issues with using the thread cutter. I have used them all 3 machines and no problems. I don't use if using the monopoly threads.

Look at the manual --Page B-33. There are a couple of hints about the thread cutter. Hope that helps!

I did see that, but nothing seemed to pertain to my problem. Did I miss something?
