Thanks everyone,
I am pretty pleased with myself. Paco is computerized so it's rather scary for me to even go after him with a set of tools......LOL
I hate to start messing with their brain pans (LOL) and the tensions on either machine. But I save all the manuals and books that come with them so I can at least find the default setting.
I really didn't care for her attitude anyways when she found out I didn't buy the machine from her. I had gone into her shop when I was looking for an embroidery machine, but she kept steering me to a more expensive model with stuff I didn't want or need.
So I ended up buying Paco from a store in New York, where the gentleman who took my order was extremely polite. I had called him a couple of times to ask questions each time he was a gentleman.
