The first few bobbins seemed quite loose but I'm not sure what I am doing differently but they are fine now. I don't use my machine on a frame but I had a lot of trouble with he machine shredding my thread when FMQ. I only use Guttermann thread now as it seems it the one my machine likes. I also FMQ with the feed dogs up and stitch length set to 0. I seem to have more trouble when I drop them and also when I use the single hole plate converter thingy. Keep trying things, you will get to know each other.
