I have a stitch regulator on my Janome 1600P and lately it's not all it's cracked up to be. Suddenly my stitches are tiny and then skipping stitches by more than an inch. The machine itself has been in the shop twice within the last four months, so it's not that. Right now I have to take a quilt off the frame and get the seam ripper out and remove all the quilting....I'm ready to give up and sell everything off.
