What has been discussed and what hasn't? How about: thread needles(type, brand, size, burrs) needle orientation presser foot height speed who digitized the design or is it stock design? dense design type of material being sewen on nick or burr on retaining support finger machine lubrication bobbin tension humidity(dry thread)Vegas is pretty dry The list goes on.... If all of the above and more have really been eliminated , it does leave the immediate area of the rotary hook and needle plate suspect. If those are found to be ok, then my gut tells me to remove the retaining support finger , feel the face of the finger and look closely at the face of the finger with a magnifying glass...if it is burred it must either be replaced or polished out. It must also be replaced using the gapping tool supplied with your starter kit or the machine will not sew properly.
