I bought a frame with Juki TL98E and "Quilter's Cruise Control from a friends estate last Fall. I've done maybe 6 quilts with some bit of success, but am now at the end of my rope (no more knots to tie in the end) and so tired of picking out stitches. I have changed needles, threads. bobbin cases over and over
to no avail. I can do about 2 passes without problems. then it begins to skip stitches. Here is example:
See in the pix on L..a loooong stitch over the scissors, and another near left edge. The 2nd pix shows
long stitch over hem clip. I'm using the med stitch setting on the cruise ctrl, but I get the same results with small or large stitch setting. Does this sound like the machine or the cruise cntrl? I hope someone can give me some suggestions or tho'ts on what the problem might be. I think I will commit hari kari if this is not resolved soon. Or else I will go back to my ''sit down'' fmq. Pls voice your opinions..it may be just a small thing that I have missed. TYIA
