Hi,
I have had my TL18SL almost a year, and recently it refuses to stitch sideways with the stitch regulator on. The needle stops, and when it does move, it pulls the thread and makes a few large stitches. It moves north and south in a perfect line, however. I've contacted two dealers, checked the plug ins, the encoder wheel, the encoder plug in, and the rails for lint or thread. Sometimes it will move one or two stitches sideways and then dig its heels in. Have you had this problem?
