Hi everyone, my 2010 Millennium has sat untouched for a bit over a year after the death of my son. I finally decided I was ready to quilt again, and have spent the past week doing cleanup and maintenance. No matter what I do, my bobbin thread is peaking through to the top. Please keep in mind I've owned this machine for 8 years and am pretty comfortable with it and its quirks.
I have rethreaded multiple times, tried different threads, changed needles (using a 4.0), change needle position slightly to the right and left.
I've made certain that all of my thread guides are in the correct position, nothing is catching on them, and my tension spring is at 11 o'clock as well. I cleaned thoroughly between the tension disks with rubbing alcohol.
After cleaning under the bobbin case finger and no luck, I opened a new bobbin case, and new bobbins as well. I doused out the bobbin area with WD 40 with the machine on high speed, blew it out with the compressor, and re-oiled.
I checked the hook shaft for play, there is none.
I made sure my hopping foot was level and at the correct height.
I can loosen my upper tension til there is nothing left to loosen, and tighten the bobbin tension until I can't even get it to drop with the drop test from a hard shake, and STILL the bobbin is peaking to the top, and on sharp curves, it's pulling to the top. This makes no sense.
I can turn around and loosen the bobbin tension back to normal (I adjust mine like Jamie Wallen, that's always been perfect) and tighten the upper thread, and it pretty much looks the same, other than the stitches are looser.
What can I possible be overlooking? I am so frustrated, I've spent a week trying to sort the tension out. I sent an email to support last night, what happened to 24/7 support? I called this morning, and they're closed.
Sorry to be so grumpy. It's not like me to need help with a sewing machine... ever. LOL
