Burr on the rotary hook-from a broken needle at some point OR a needle that moved during sewing because a hat shifted or heavy jacket pulled it sideways. Doesn't take much to affect the thread. thread breaking-back to the needle plate-if it is even the slightest fraction off-it will rub the needle. My wife cannot set it dead on-I have to do it. She looks at it with one eye and not both. I have to use a magnifier (eye surgery earlier this year) but I did jewelry work for 25 years so I know how to see small stuff. crunch noise-just had that happen this week for no reason. Had used big red a couple days before with no problem-started it up for another job and every time the needle head moved, got this bad sounding 'crunch/pop'. Called our local tech and he heard it on the phone-identified it as the white 'cog wheels' being out of whack (why, we still don't know!) He had me hold the laser button and up arrow, cog would pop, then move to the next needle and do the same all the way down. That reset the teeth where they belonged and it hasn't happened again. Maybe someone bumped into the needle head with a box walking by it or something-who knows. But it stopped. =========================================================== The AmayaUsers Mailing List Website: http://www.amayausers.com Discussion Board: http://www.amayausers.com/boards Subscribe/Unsubscribe: http://www.amayausers.com/list ===========================================================
