I've been struggling with the tension on my Mega Quilter. I can't seem to get the bottom tension where it should be. I've had it cleaned, I oil it lots, I've done everything I can think of. If I adjust the top tension to where the bottom looks good the thread continues to break. King Tut has always worked good for me - Aurfill which I would like to use just does not work at all. I did buy a 2nd bobbin case to fool with but have not worked on that angle yet. I also switched to a 75 needle and that may have helped the thread breaking issue but why is this causing me so many problems now! I know with the Mega Quilter you have to use a HLx5 Needle or that could cause problems so I've always used that number and just used 90,80, or 75 sizes. Can anyone help? I'm at my wits end!
