I'm working on my very first quilt, so I purchased a walking foot for my machine. I heard that a walking foot would make quilting so much easier.
Well, I'm frustrated and struggling. I've only quilted about 4 of the seams so far. First, I was having trouble with needles breaking, so I put in a heavier-fabric needle and forced myself to stop subconsciously tugging on the fabric. I thought that would help.
But now my walking foot is doing this weird jumping thing. It's like something is getting stuck. The whole walking foot will get lifted up and then slam down. Not only does it startle me so bad I almost fall out my chair, but I'm afraid I'm going to damage something if I keep going. Sometimes it does it on every few stitches for a while. Sometimes it only happens once. And sometimes it goes smoothly for quite a while.
When this happens, sometimes the stitches turn out bigger than they're supposed to be and sometimes they turn out tiny. Sometimes they look normal, but it will jump away like 1/16 or 1/8 of an inch from where I was stitching.
I've taken my whole needle plate off and gotten the dust out of the bobbin case, changed needles (the one I'm using now is not bent, but it still does this), etc. I've never had any experience with skipping stitches, so I thought maybe that was the problem, but I've followed all of the suggestions for troubleshooting in my manual. Can anyone help me?
I'm using a Brother Innov-is 40, if that makes any difference.
