Update on my sewing/embroidery machine

When I brought my machine to the shop, a couple of weeks ago, the person in the shop who checked it, made a couple of changes, one in the machine's software and the other was to lower the feed dog and it seemed that no other adjustment was needed, so it was only a matter of testing the machine.

I didn't have much time to test my machine immediately and when I tested it I found that those changes weren't enough. No matter what needle/speed or tension I have tried, the result was always a bird nest underneath. I vacuumed the machine, bought un-waxed dental floss and dislodged a piece of thread, but that wasn't enough to avoid bird nests.

Today I brought my machine back to the shop and that same person checked it better and found that a little piece of metal which takes and moves the tread, was worn out and the take-up lever had a strange coating and couldn't figure out what it could be. Then I remembered that a member of my family had sprayed my machine with an adhesive/sticky substance.

Now my machine is due to be picked-up by a mechanic who will do the service and it could take up to 10 days to have my machine back
