Hi, I have a Tin Lizzie 18, the older, heavy one, purchased second hand about a year ago. The machine had been back to the company for service before I bought it. I've quilted at least 25 quilts since I've had the machine. I used the stitch length regulator for a while and it worked fine. Then the little tiny plug-in under the top layer of the carraige kept coming unpluged. When this happens , in stitch-regulated mode, the machine goes crazy! This is not an easy thing to remedy, the machine has to be taken off the carraige- it weighs 95 pounds and I'm old.
I was all ready to call the company but thought I'd try to finish the quilt I was working on without the regulator. I did fine without it, I don't need it! Maybe I will call and order new encoders/plugs after the holidays but it isn't a big thing to me.
I hope you get your Lizzie up and running soon.
Mary
