I need some serious help. I am having trouble with the mega quilter. The thread keeps breaking and sometimes the needle breaks. I can't keep the tension the same even on the same quilt. I have read previous post and changed thread to Star, it broke worse, Essential, it shredded, Coats and Clark, I won't even go there. It was the worse. I changed needles to top stitch needle and ballpoint needle and that did not help at all. I put tension between 4 and 5 and tension was worse and could not sew 20 stitches without thread breaking. I have used cotton batting and poly-fill batting and that does not make a difference. I watch which side of the batting goes upwards and no difference. The thread keeps breaking. I have had this machine about a year and it has been in the shop and they say there is nothing wrong with the machine. I do have cruise control on this machine and all the connections are connecting and I think they are correct. Any suggestions?
