I have a pfaff grand quilter and have used it to do six quilts and has worked great but the last quilt i did the top thread kept breaking every few inches i have tried everything but in the end took it in for full service got it back and still the same it seems to be getting caught in the tension knob also it has started to skip a lot of of stitches and has one long stitch every know and then i am trying to fix as i go because i can not get anyone to come and have a look as they are to busy i am wondering if the stitch regulator might have something to do with it as in the shop with the foot on it works good. the shop i took it to will not help he had my money

I had a similar problem with the long stitches. One of the encoders for the stitch regulator was not turning all the time when I moved the machine. My dealer gave me a new one and now the machine works fine. It could also be your cable from the encoders to the machine. If the wires (very fragile) get broken, either the machine won't sew when you go side to side or back and forth, or it will make the intermittently long stitches you mentioned.
It's important to have the foot raised when you thread the machine. If you have it down, the thread won't get caught between the tension disks, and it will be very hard to get consistent stitches.
I have a Pfaff Grand Quilter and it is doing the same, it sews for about 5 minutes (I am using it on the Inspiration Quilting Frame to long arm quilt) and then the thread breaks. It's very frustrating. Any suggestions. I have changed the thread, the needle, the tension, nothing helps. HELP!
