My machine quit working last evening--no loud noises, no smoke, no warning. The needle just stopped engaging.
While getting it ready to take to the repair shop, I had it on its side and noticed a button that looked like a resolution button. This machine is the Bernina 1530, one of the early computerized machines. I bought it in about 1993. The past 6 months I thought the screen was burning out as it was very difficult to read. I would move the mouse as far as I thought would be enough by memory to get to different stitches.
It turns out someone had turned the resolution button way down. Finding this out at home saved me from my fear of a big ticket repair and from embarrassment at the repair shop.
It is difficult being in the house without a working machine--my backup is at the arts center. I took in the 830 found at the thrift too--we are going to have it set up for the rest of the family--maybe it will keep them away my machine and from the resolution button---, the one I didn't know existed despite 17 years of daily sewing!
