SE270D thread piling up
I have a new SE270D and am having trouble with the thread. It keeps winding/piling/bunching up under the plate. I've cleaned the shuttle, changed needles, etc. and it keeps happening. I'm trying to make a rectangle patch. I'm using embroidery thread in top and bottom, I'm using canvas type material on heavy duty stabilizer. It's to the point that I have to pry up the material and cut the thread from the bottom. I thought it might be the material combination so I tried a piece of cotton fabric with tear away and then water sol and it did the same thing. I even tried just fabric by itself. Please help!
