Janome 1600P & Grace Frame SR2+

The Janome 1600P keeps breaking. I have re-threaded it many times. It seems to be getting held up on the tension dial on the front of the machine. I have turned that dial up and down, nothing seems to help. Does anyone have any ideas?

Did you ever resolve this issue? I'm just starting to work with mine and am a bit worried that it will not be able to lift up enough for a longer quilt.

I know it has been a while so these are some of my finished work completed with the Grace SR2 frame. https://massdrop-s3.imgix.net/img_comment/ZeLSSoo9QW2W7HTUbakw_017.JPG https://massdrop-s3.imgix.net/img_comment/vGQSJUasRgycI6IKAFux_003.JPG https://massdrop-s3.imgix.net/img_comment/ZIMHlX4lTKyWyc2OfP7r_015.JPG https://massdrop-s3.imgix.net/img_comment/Ni3uRwmPTm2HnrbM2CGF_004.JPG https://massdrop-s3.imgix.net/img_comment/yvtZ5zQyGRLNVCcqkAgQ_003.JPG https://massdrop-s3.imgix.net/img_comment/eABHsLKZRGOmjKdkMbuQ_005.JPG I just love quilting on my Grace frame and my JUKI TL 2010 Q.
