The BSR sets the stitch length "automatically"...I'd guess about 1.5. Anyhoo, I managed to finish the quilt, have printed off all the different messages regarding the spring & updates and am taking it to the shop tomorrow. It hasn't always done this....only does it about 15 minutes into quilting...I think it needs to be checked for updates and a stronger spring. Been doing this over a year with the BSR with no trouble before now.
