Well, that didn't work.

My thread is still snapping but the tension of the stitches looks perfect....I checked that the top thread unrolled the right way (Dianne- yes the thread comes off the spool at the front as you say it should, which I'd call clockwise now after all that- the Aurifil does still go the weird way round for this, which seems odd but there you go). I asked the thread if it would rather go vertically on the pin (it didn't). I rethreaded both threads, and put a new needle in. I even changed the bobbin over for a different one as suggested by Leanne.I also checked the stitch plate for burrs by putting a loose bit of the cotton through the plate and rubbing it around the edges. It seemed fine but I moved back to my standard plate anyway, JUST IN CASE.I'm at a loss, I really don't want to move the bobbin tension back as the stitches look great now, and I was having the snapping issue before I changed that. I've already switched over to Aurifil on the top as I was previously using Coats but having the same problems. I slackened off the top tension a notch or two as well and discovered some trapped thread in the tensioner which I cleared out. The problem seems to be occurring when I reverse stitch most often- does that mean anything to anyone?Sorry for the moan, I guess I'll have to wait for a few days and get on with something else, it's so infuriating. I could probably do with removing the top and seeing if there's anything else stuck in there that shouldn't be but it's like a fortress! I'd practically have to take the entire front off- no easy access top hatch for me. Reminds me a bit of certain manufacturers of cars that make it near impossible to change a headlamp by making everything so inaccessible you have to go to a dealer for the simplest of jobs.And I might end up there next week if this continues, I don't really have time for this though as the entries for Festival need to be in by mid July.***In the meantime, I have projects in the July editions of Sewing World and Popular Patchwork, the first was out last week, and PP is out tomorrow.
