Hi,

I'm new to sewing machines. We bought a used Janome New Home (a.k.a. Derby) sewing machine for my daughter.

It worked fine for about a month. Then it started skipping stitches pretty badly. We watched all the tutorial videos from Janome, triple-checked both top and bobbin threads are threaded correctly, changed the needle a couple of times, cleaned bobbin case, checked timing, bought a thread spool that seems to fit the machine well. In short, I tried everything a newbie like me can try, but still can't make it work. It still skips stitches a lot (it seemed to improve slightly after changing the thread spool, but still not usable). I've uploaded the video that shows how the machine behaves.



So this forum is our moon shot ... Can anybody tell us what may be going wrong, or advise us the next troubleshooting step?

Like I said we're new to sewing machines. Any help would be greatly appreciated!

Thank you,

Nao

P.S. We've noticed that it takes several rotations (say 10) for top thread to pick up the bobbin thread. Can this be a clue to the root of the problem?

Have you checked that the distance between the hook and the needle are in spec?

yeah i agree with Revv Up sounds like the hook and needle timing are off.

Thank you very much, Revv Up, John.

I've found this text on a Janome manual:

WHEN THE TIP OF SHUTTLE HOOK MEETS THE LEFT SIDE OF THE NEEDLE IN ASCENDING
TRAVEL OF THE NEEDLE FROM ITS LEFT AND LOWEST POSITION, THE DISTANCE
BETWEEN THE TOP OF THE NEEDLE EYE AND THE TIP OF THE SHUTTLE HOOK SHOULD
BE IN THE RANGE OF 2.9-3.5 MM.

This is the issue you are talking about, right?

I will try and check this . Thank you!!

Wow, this fixed it! Hook - needle distance was the problem!
