It sounds like your thread feed drive gear is cracked. Easy Fix, you can do it
yourself. Take apart the upper clam shell covers behind the needle case. You
will see a single white plastic drive gear. Laser Up Arrow will advance the
threadfeed. You will be able to see the gear wobble in and out of engagement
from the threadfeed assembly. You will need a precision small pliers for
retaining clips in order to get it off. When you order the gear make sure you
also order a couple spare clips, you will loose and/or bend them. Don't forget
to grease the inside of the gear with Polymer. To get the gear out you can
either order a Fixture (Recommmended) or you can remove the circuit board
directly above the gear. If you choose to remove the circuit board make sure
you mark exactly where the board is before you remove it. The board can be
adjusted front to back to center the drive gear to the thread feed assembly.
Good Luck !!!
TJ.
