Re: Stitch issue on 7700


Hello Jim,
thanks for the diagnosis.
And excuses for the confusion, this is a thread issue with the 12000, but I thought it was similar to the one of the 7700 as the lady mentioned the tiny loop.

I'm a little confused. Your post said it was a stitch issue on the 7700, but that machine can only go to 7.0 on the right. Only the 12000 (or 8700, 8900, 9900) can go to 9.0. Still, the problem is the same, no matter which machine is involved. I believe the hook timing is off just a bit. What's happening is that the tip of the hook is arriving a little late, as the thread loop is pulling up. Mostly it still catches the loop, but sometimes it pierces the thread, keeping the loop from pulling up until it breaks free from the hook. It's also possible that the timing is fine, but there is a burr on the tip of the hook. Either problem can be corrected by your dealer.
