I normally sew clothing etc. and I never had this problem. I'm new to quilting and just discovered this issue trying to sew a quilt.
I had my stitches on 2.5 they were to tight so I put them up to 5.0., I'm stitching in the ditch slowly.
my machine does embroidery also and I think personally when they add these extra things to a machine it takes power from the machine, ie the motor which the machine probably would sew faster
if it did not have to perform all these extra tasks. The distributor said not true but sewing on this machine for 3 years now i don't believe her after learning to sew on a workhorse of a Singer 30 yrs ago.
