Singer Futura CE-250 thread tension issue 6/6/2012.
Here is the 6 different tensions I 'set' the machine to trying to get any 'tension response'.
Showing the machine as setup to start this test/example.
Showing machine set to S & using black top thread & red bobbin before starting 1st test
Showing machine set to 03 (zig zag stitch) before starting.
Result of sewing zigzag in the default settings (ie pressing the zigzag button w/o making length/width changes)
& setting thread tension to 'S'.
Sewing with thread tension at 4
Sewing with thread tension at 'E'.
