Can you sew a little slower? (I know I'm asking a lot) This may sound weird but my husband installed dampeners Used for bow hunting for vibration and noise it works they now have peel and stick ones we had a archery shop- me quilt shop thats how we got the connection. My table is 14ft and when in middle machine wanted to do the 'hop scotch' found if slowed down and with help of stabilizers things mellowed out and should help with light. If hubby is into archery he will know what I am talking about!! Good luck
