Maybe try a needle one size up??

Usually when this happens to me (I have a Pfaff Grandquilter, 9" throat, on an Inspira frame) it is because I have the take-up roller too high above the sewing machine base.

There has been a lot of really good information shared here and I hope that it helps you out. Welcome to the board and I hope to hear that you solved your problem and are back to quilting by the time that you read my post. Good luck.

Try different thread, my old machine wouldn't sew with one brand. Check the throat plate for a little burr. I have had good luck with a denim needle.

I had this problem fmq on my Bernina. I finally changed to Signature thread and organ needles.

Thanks for the suggestions,hopefully one of them will work. As for needles I've tried Schmetz 110/18, 90/14 quilting 80/12 topstitch and Superior Titanium 110/16 & 90/14.

Hello, Please clarify: spacing incorrect for the sandwich and machine bed. The sandwich is skimming the machine bed, not really any daylight between the two. As for too tight - do you mean the clamps on the edges (not on the rollers)? Thanks for your help!

Hello, The sandwich is skimming the machine bed, is that low enough? Thanks for your help.

Hello, How did you know your timing was off? It is visual thing? Thanks for your help!

Hello, What is the sure stitch? I check all the other settings you mentioned and oiled it in the bobbin area. I'm not up an running yet - tried to sew again; it did fine off frame, on the frame UGH!@$#^$*@*(% Thanks for your help!
