My tall thread stand took care of pulling my hair out, as I got caught in it a few times while contorting myself in and around my machine taking it apart and trying to find the culprit. While there were plenty of tiny lint and threadlet pieces in and around my bobbin case/race — which I spent over an hour cleaning and recleaning — the problem was not lower thread, it was, in fact, my upper thread path to blame. Specifically what’s behind DOOR NUMBER TWO!
I have a new PE-770 and I’m attempting to get a new Etsy shop off the ground. While I’m new to machine embroidery, I have been machine sewing (and hand embroidering) since I was in grade school. Ergo, I know my way around a sewing machine.
I experienced my first bobbin “bird’s nest” about a week ago (with daily, fairly heavy use). Cleared it and moved along. Today, out of the blue, a massive bobbin bird’s nest developed. When I say “massive,” I mean it took me a good 20 minutes to cut (with an Xacto blade so I wouldn’t ruin any of my small scissors) and tweeze out. I thought small insects might fly out.
But once I got going again it would immediately reform. Cleaned again. And again. And again. Three different tweezers, Q-Tips, you name it.
Read initially on another sewing blog that mysterious bobbin issues are actually upper thread path problems. And then I read the above. (Keep in mind I had already removed the obvious upper thread path cover to check for threads.) Sure enough, once I removed the cover over the upper path #1 & #2, there was an obvious mass that was easy to remove.
But at that point I was not in the mood to reassemble and fail again, so I busted out the mini book light and got to looking. Sure enough, there were tons of black threads (black from grease, as I hadn’t used any black thread) wound around the whatever-you-call-it that rotates inside with the wheel.
There were so many! I had experienced a lot of upper thread breaks before getting my spool stand (and ditching that useless horizontal spool under the cover), so they had been building for who knows how long. It took a good half hour just to tweeze those out.
Problem solved. After three hours.
Then I promptly made myself a gigantic margarita rocks, loaded a small hoop for testing, and watched it go. Margarita is almost dust, but my project is back on track.
(This is an old thread, but it came up second on my Google search, so hopefully this is helpful to others with Brother PE-770s who are as vexed as we have been. THANK YOU Ann The Gran!)
