gives the bartack width. The bartack width can
be altered with the corresponding parameters
“offset l” and “offset r” in the bartack menu.

The final bartack length is the same as the first
bartack length if both bartacks are identical.
The bartack length for both is set in the menu
“First bartack”.
Buttonhole length
The complete buttonhole length is determined
by the cut length + length in front of the cut +
length behind the cut + first bartack length +
final bartack length.
