I bought the machine last month, I like it. Someone on another forum asked about thread coming out of the needle when using the thread cutter.
Mine does that - but the thread is curled! It springs out of the needle when tension is released.
I can see it curled when the takeup lever is at the lowest position and the needle is still in the fabric. The thread is curled in between.
I've been using Aurifil and now trying Prescencia. They curl. I had the tension looser since I was playing with 2 colors and didn't want the bobbin thread on top. It curled. I tightened the tension back up - it curled.
Serger thread does NOT curl. I use that when practicing since I have so many colors. A King Tut multi that I had bought for embroidery on another machine does not curl. I used the same spool of Aurifil on my Pfaff 2170 and it does not curl. It has nothing to do with the vertical bobbin as the Pfaff has the same setup.
Machine is threaded as shown in the manual. The 3 hole guide is as shown, but the text said you can adjust by using either one or all 3 holes. Haven't tried changing that yet. Can't seem to find which hole would be best.
The only things I know that make curls is pressure or heat. Since the thread is external, I doubt it's the lamp.
I can feel a hitch somewhere when I pull needle thread. I usually grab thread from the machine needle for hand sewing as it's handy. I thread with the foot up from long practice. Other than the curling thread the machine is working just fine.
What can I check and how can I check it?
