I'm having a problem with the upper thread breaking when FMQ. I did lots of FMQ with no issues prior to this. I've tried adjusting the upper tension down all the way until i started seeing loops on the bottom then turned it up tiny amounts until there were no loops. I've cleaned out all lint and oiled the machine. I've used organ needles, schmetz quilting needles, schmetz universal. All brand new needles. The tension disks are clean. I've re-threaded the machine numerous times, looking at the manual to be sure it's correct. I'm using Gutermann thread. Does anyone have any ideas on what else I can try? When i sew straight without FMQ I have no problem. I'm using a generic FMQ foot. I have the stitch length adjuster turned all the way out so it's what 0 would be on another machine. Here is a photo.
