Motor Lagging? Brother SQ9050
Oh my. The Husband bought me a Brother SQ9050 for a back up machine about three months ago. I do a LOT of piecing, but I really haven't done a ton of free motion quilting on it. Over the past three or four days I've put about 4 hours at a time into quilting a couple holiday wallhangings...now the motor seems almost like it's lagging or slow. It goes through spurts, where it seems slow, like it's on the verge of croaking, then comes back to life. I've unplugged it, checked all the plugs and attachments, cleaned the bobbin area...are these Walmart Brother's really so flimsy that free motioning a few wall hangings would burn it out? I mean, albeit, it's dense quilting, but I didn't think I'd kill it THAT quickly.
Or maybe there's another issue I could have overlooked?
Anyone experience this?
