I am sure hoping that the Juki owners or repair experts here can help me. I am rather discouraged.
I have 2 quilts sandwiched and ready to be straight-line quilted with a walking foot on this wonderful machine; however, in running settings and test sandwiches, the lower feed teeth are making visible (and somewhat alarming) indentations in the backing.
The presser foot pressure has been set anywhere from zero to the halfway mark. The marks are much less at zero, but then there is some distortion when going over seam allowances. It's pretty discouraging to take perfectly straight seams and then have them made wonky in quilting.
I also tried the regular stitching foot, with little pressure, and there weren't marks. However, that didn't allow for enough push to keep the seam allowances undistorted.
I called 2 local dealers. With one, I was able to talk to the technician, who tried to get me to have the machine "tuned up" and finally said, after I pressed the point, that he had never seen the problem I was describing.
The other shop owner asked me 2 interesting questions: do the marks come out after washing and could it be that the batt (QD request) was just too thin for such a strong machine?
Ok, so the marks do seem to come out after washing, but I am not really comfortable with the idea of the teeth hitting that hard. And indeed, the problem is somewhat reduced visibly by making the batt a bit thicker. But both quilts are sandwiched and pinned.
Could it be that the teeth are too sharp? Is my backing (navy Moda marble) just showing this more than another fabric would?
grateful for any opinions,
Charlotte
