I finally set up my embroidery module on my Bernina 440. It worked almost smoothly but I am having trouble with the bobbin jamming up when I change colors. I had to stop & clean the bobbin case each time. It made the 37 minute task take all evening! But I am getting better & faster at cleaning that puppy & putting it back together :lol: Any thoughts on why this is happening? Any hints or tips to use to make life easier with my new toy? Thanks!
