Sue had bobbin 'break' one after another without any really thread break...trying to sew out one stupid scarf monogram! Changed bobbins, went to magnetic, changed needle, added more backing, doubled up on solvy...then finally checked the roller and that was worn! (Yet we hardly use the Amaya anymore...really surprised at that!) We have the new upgrade roller kit but until we use up the rest of the black rollers we aren't installing it...don't want to throw them away. Changed the roller-no more thread breaks. Second job I was trying to do-sewout test-nothing but looping and birdnesting, breaks, looked lousy. She changed needles, ball to sharp, thinner needle, thicker needle, MT, speed, spent 2 hours tearing her hair out. I went and reset design, changed fonts to wireframe, everything...then decided to see if the pressor foot was done on the material.... Duh, she had switched from hats to flat-and had changed everything EXCEPT checked the pressor foot! Next sewout went with no breaks or stops...did the one item and shut it down for the nite. Have to post a sign next to the Amaya....'Check rollers' AND 'Check Pressor Foot'! Roland
