Tiny stitches...Help
 

Recently my machine has started hesitating at seams & sewing really tiny stitches. I've cleaned, changed threads & needles. Still have the problem. Is this a timing thing.

Is your machine computerized? It might help (if it is) to turn it off, then back on a readjust the stitch length. I really have no clue, but it's worth a try.

My old Bernina 930 does this sometime. Most of the time I have knocked the gear up that lengthens and shortens the stitch when I was wrestling with a large quilt. Another time I leaned over the machine and knocked the gear up. I need to tighten it a little more, but then I have a hard time loosening it to change my stitch length again.
I don't know if this will help.

What machine do you have? I have this problem on my Janome if I forgot to engage the acufeed.

Are the feed dogs up? They need to be up to move the fabric along.

have your feed dogs been cleaned? lint can really pack down in between them and that doesn't help them work well at all.

This was the problem with my Bernina. Now I check/clean them regularly.

If the problem with your Janome happens without using the AF, I suggest you see if the O2 foot fits your machine. I have the 6600. I was having problems with it hesitating at bulky intersections an seams. The O2 took care of the problem. The underside is different from the O foot.

This is my guess, too. Basically your feed dogs aren't doing the job they should be, so the first thing to check is that they aren't clogged up with lint.
