2.3 The use of straight stitch feet with thread cutting
The opening of the straight stitch foot is 0.4mm on both sides. The “tie on” stitch after cutting is
0.4mm to the left side. After thread cutting, the first stitch failed resulting in the animation “need-
le will penetrate presser foot” due to the narrow tolerance in the foot opening. This has been
resolved.
2.4 Disable automatic thread cutting when opening the bobbin door
Previously the thread was cut automatically before the hook turned to the front.
To accommodate the need to change the bobbin without cutting the upper thread, the cutter is
disabled and the “lower thread empty” message appears.
2.5 Thread cutting without fabric movement
Thread cutting with the needle stop down, will NOT result in fabric movement.
2.6 “Manual” winding of the lower bobbin thread
The filling process stops at a detection of 100% fill level. As a result of mechanical tolerances, it
is possible that the bobbin does not fill to the maximum capacity.
