Optimizing the stitch
Stitch optimizer Thread tension
The stitch optimizer helps to achieve the
optimal stitch.
Prerequisite:
•The sewing test was performed.
> In the stitch view, tap «Stitch Optimizer».
Imperfect stitch images are shown.
> Tap the stitch image best matching to the
sewing sample.
Corrective measures are proposed.
> After each action, reassess the sewing
test and repeat the process until the
perfect stitch pattern is achieved.
For each stitch, default values are pro-
grammed. These recommendations provide
good results for most applications.
> To adjust the thread tension, select the
range of thread tension.
> Use the slider control or the «+» / «-»
fine adjustment buttons to adjust the
thread tension for each thread path.
mtc micro thread control
By default mtc micro thread control is always
set to position «0».
mtc micro thread control affects the amount
of looper threads around the fabric edge and
can be adjusted continuously during sewing.
> To enlarge the loops of the thread at the
fabric edge, turn the mtc micro thread
control clockwise (+).
> To minimize the loops of the thread at
the fabric edge, turn the mtc micro
thread control counterclockwise (-).

Differential feed
The two feed dogs can be geared to each
other so that the fabric is fed evenly while
sewing and that neither wavering nor
unintended gathering occurs.
The differential feed is variable while sewing.
Gathering
Gather to fit
To prevent waving increase differential feed
to a value between 1 and 2.
To gather intentionally, increase differential
feed to a value between 1.5 and 2.
An elongated stitch length enhances the
gathering effect.
Stretching
Default value
To prevent seam puckering, reduce
differential feed to a value between 0,7 and
1.
The differential feed in default setting 1 for
flat and even seams.
