I hate to say this but if it were mine I would not have it repaired..you have soaked way too much money
into a machine that is not used that often....as you have said......bring it home, spray paint it yellow ( for lemon) and use it for a door stopper! In the meantime check around for a reasonably priced combo machine that will satisfy your urge to now do "some" emb. Projects...JMHO. As an aside, I would take a pic of the " new" yellow .machine along with its "history" and send it to the mfgr......will not get you anything, but a bit of satisfaction! I have done this to several items that have proved not worth the cost........
