I just bought a used Megaquilter 8x8 on a Grace frame with a stitch regulator. I have the frame and sewing machine set up and can quilt just fine with the foot pedal (not that it is fun, moving up and down the quilt with my foot in one place!!) but when I hook up the stitch regulator and turn it on, the red/green needle up/needle down lights alternate and the sewing machine refuses to do anything. When I turn off the stitch regulator with it still plugged in, the needle up/needle down button works, but of course I can't sew. What do I need to do to make the Megaquilter not choke with the stitch regulator? The stitch regulator has power and is set at a medium stitch length, right at a white dot near the middle of the speed control. Speed on the Megaquilter set in the middle, as suggested. Thoughts?
