Argh had my post all typed out and my laptop ate it! here it goes again.
The thread I was using was Aurafil 30 wt. good quality cotton thread I had it on the embroidery thread holder with the thread loops extended about 6-8". Also tried it with the thread spooling off the spool horizontally. No difference. I have tried cotton, silk, polyester, waxed cotton. I have also tried 3 different needles. all topstitch, 80, 90, 100. Brand new needles. Upon closer inspection, it seems that the needles are grabbing onto the fabric and pulling it up on the upstroke. I dont know if this is new or not. Never paid that close attention to it.
The machine is set up for freemotion with the appropriate foot. now comes the creepy part.... take a look at the video. This happens after I push the needle down button during the process of bringing up the bobbin thread to the top. I am not touching the machine at all during this and the foot pedal is free and clear. http://www.twitvid.com/Y6CBO
I havent done much quilting lately and come to think of it, I dont know if I have really ever sucessfully (without pulling my hair out) quilted a top on this machine.
Was wracking my brains trying to figure out how I could afford the Bernina 820 (keeping the pfaff for embroidery) but now I'm hearing horror stories about them.
I equate this to another holy grail quest...I also do flameworking or lampworking. Making glass beads on a torch. The holy grail there is the perfect clear glass that is compatible with other glass. In quilting its a machine with even stitches and a long throat. Shouldnt be too hard huh?
I have one other top to quilt. This one is batiks top and backing. Lets see if I have troubles with that. You may hear me scream.
