I have this persistent problem with no solutions. My dobby III correctly produces the correct pattern for about 1/2 hour. Then it skips at a pretty regular interval. Whether it's a simple plain weave or a 16 shaft pattern, same thing.
Anyone out there experience this and have you ever resolved it.
I'm beginning to wonder if it's a heat thing in the box.
I have worked with AVL in the past with no results.
It's not just me. My friend with a dobby3 recently switched back to the mechanical dobby!
Thanks for any insight.
