One is that every so often the thread jumps out of the take up lever and creates chaos and bad words til you realize what is wrong. The other is that it seems to have a hard time going over bulky intersections. There is a new foot O2 that helps with this problem. The Yahoo group knows a lot more about this machine than most dealers do!
I have a 6600 and have had problems sewing through many thicknesses of fabric/batting (I make handbags). I'll look into the 02 foot, which might help. Thanks for the hint!
The other issue (thread jumping out of the take-up lever) I was aware of, but the solution is easy (bring the thread up to the left and then down to the right so that it loops around the lever).
Another point...my machine seems to run better since I started using Bottom Line thread in the bobbin.
