Janome 6600 is stitching funny
 

Today hasn't been one of my better days at the machine! Mistake after mistake....and now this crazy machine is sewing like my brain has been working....crazy! It seems to sew fine, can't see anything while it stitches. But when it is done and I look at the stitch line, it looks like it is stitching in a slight angle and about every 7-8 stitches it jogs just a bit. I have never seen it do this before and have no idea what to look for to fix. Anyone else out there had this issue? Help me! I have too much sewing to get done before Christmas to take it in for a visit at the repairman.

Here is a sample of what it is doing

WOW, I have never seen a DSM do this before. When did you last have it in for servicing?

You might have a problem with one of the gears. Sorry, no way to fix it yourself.
You'll have to take it to the repairman. Maybe you can get a loaner while yours
is in the shop.

Call your dealer. That doesn't look right at all. Good luck.

Before taking it in for repair, I would change the needle, change the bobbin, and give the machine a good cleaning. Hope you are able to get it sewing properly, since you are busy getting ready for Christmas!

What kind of fabric are you sewing on (the grey)? From the picture, it looks thicker than quilting cotton. Are you using the right size needle? It looks like the sewing thread is jumping over the woven threads from left to right of the weave. The edge does not look like it was cut perfectly straight (which is no big deal) but if it is a coarse weave and you are trying to stay so many inches away to make the straight lines, that might be why the stitch is jumping a thread. The needle is not piercing the thread, it is going over it to the next side. That is what the problem looks like to me from the picture. Are you using a ball needle?

It's just because of the grain of your fabric. You can see that when the stitching crosses over the grain line, is when the jog happens.

on the front of your machine there is a stitch balance adjusting screw I spent 80 dollars to have the repairman turn that screw about 14 inch. play with it turning one way or the other to see if it helps

Mine does something like that if I forget to thread it thru those two things that stick up in the back!
