I learned with my BL Quilter's Choice that it helps to have the tension a little loose on both top and bottom. See Jamie's Wallen YouTube on adjusting the bobbin. The reason is due to the speed of 1500 stitches per minute, so the looser tension helps the thread move more smoothly with the fast moving needle. I check my tension each time I change the brand, thread weight, etc. I upgraded to a mid arm machine recently and still keep the tension same as before.

Though I would rather spend my money on fabric and thread I do have my machines professionally cleaned and adjusted regularly so that I don't encounter this type of problem. I have BERNINA machines. I have an 1130 that I have had for more than 30 years. The technician says he has never seen a machine any more used than this one. I used to make draperies professionally. And yet, with regular maintenance it works perfectly. I clean it regularly as I sew. However, when he takes it apart I am amazed at all the lint in places I can't get to. I think you need a trip to the dealer as a beginning point.

There is nothing more frustrating than tension issues! Hope you get it solved.

It's just a screw. I turn it all the time. I start with it very loose and tighten a little at a time until it has some resistance. Just don't take the screw out, you will lose it!

it is usually the top tension that needs tighten up
