[Setting the number of condensation stitches]
[Setting the condensation pitch]
If the condensation pitch is decreased, the phenomenon where the needle enters the same
needle entry point will likely to occur, resulting in unstable formation of thread loop at the time
of thread trimming. As a result, thread trimming fault is likely to occur. It is therefore necessary
to adjust the condensation pitch carefully. (The needle entry phenomenon differs according to
the material to be sewn and the needle count, the pitch should be increased if thread trimming
failure occurs.)
In the case of carrying out shorter-thread remaining
thread trimming (when condensation is placed in
ON), set values of the condensation pitch and the
number of stitches are adjustable. Adjust those set
values appropriately according to the item to be
sewn.
1) Select "U280 Number of end condensation
stitches for shorter-thread remaining thread
trimming" from "1. Display all".
2) Set the number of stitches.
(Factory-set value: 2)
3) Confirm your entry by pressing
Then, the sewing screen is displayed.
