I don't know what a single hole needle plate is, so I don't think so- just whatever comes on the machine. The machine is set to straight stitch (and was doing one before it went crazy.)
Thank you for helping me troubleshoot.
I think I'm just going to have to wait until next weekend to take it to the dealer. I think the hole for the cone is too far forward- there is no way the foot could align properly with the needle plate as is. It has to be the foot.
I'm just doing my binding with my regular foot now :( Which means it is bunch a little bit.
I'm about ready to cry I'm so annoyed by this.
