Walking Stitches problem HELP!

[Chris & Cindy]

I have a simple design that has a 25 stitch length walking stitch. I'm sewing on pant weight twill with a 2.0 oz backing. Nothing fancy at all but the walking stitches are shredding. I have tried slower speeds down to 600 SPM and it still shreds every time. The rest of the design sews fine. I'm really confused about this? Please help!

I guess I should add that I have cleaned and oiled the hook as well as changed the bobbin and tried a different bobbin case. Nothing I have tried seems to work.

Did you check the needle? Could be a burr or the needle isn't 'centered' so it's rubbing the thread through the hole in the plate and tearing it. Been there...done that. One fast way to check is to do a test sewout and assign that stitch to a different needle and color...just for the test. If it sews fine, then your original needle may be the problem...just switch the spool of thread and continue with the 'test' needle instead of wasting time for now.
Hope it works!

Tried changing the needle as well as using a different thread and needle all together. Same problem across the board.

Isn't a 25 stitch length really short? If so, try lengthening it or deleting every other stitch (or something.) Or simply redigitize that part.

Are you putting these stitches on top of a heavy fill?- give us all the details you can.

[Chris & Cindy]

Not on top of anything except the fabric itself and the stabilizer. 40 weight thread with a 75/11 needle.

Do a "bottom center" with a brand new needle- is the needle in the VERY MIDDLE of the needle plate hole? If not, center the needle plate. You will find bottom center under Maintenance>Head Timing. I'm thinking the thread may be shredding because it's rubbing on the needle plate.

I find the most common reason thread shreds or frays is because the needle it turned too far from straight forward.

Otherwise, it could be a bad needle, scratch along thread path, presserfoot is too high, thread feed rollers lacking lubrication, etc...

What is the machine doing on other needles?
