Icon Parameter
Number of bartack sections
A bartack consists of several sections.
If the sewing direction is changed, a
new section is started.
The number of sections in a bartack can
be set here.
Stop-Time for direction
change
The waiting time at the turning points
(e.g. for a change of sewing direction) is
set at this point. A short waiting time in
milliseconds should ensure consistent
seam quality (ornamental-stitch
bartack).
Stitch length default
If this function is active, the same
needle stitch length is used for the
bartack as the one set in Manual mode.
If this function is deactivated, a custom
input can be entered.
Speed in bartack
Single stitches per pedal
If this function is activated, each stitch in
the bartack can be sewn individually by
pressing the pedal. This function can
only be used meaningfully if the speed
is set very low for the bartack.
Needle thread tension default
If this function is active, the same
needle thread tension is used for the
bartack as the one set in Manual mode.
If this function is deactivated, a custom
input can be entered.
