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.
Thread tension
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.
Optimizing the stitch
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 (-).
