Low Bobbin
The Baby Lock Crown Jewel III includes a low bobbin
capability so you can estimate how soon your bobbin
thread will run out. This Low Bobbin Capacity is based
on an estimate of how much of a particular thread can
fit on a bobbin, in combination with other quilting fac-
tors such as tension, stitches per inch, and how much
bobbin thread you pull up when beginning and ending
your quilting (
Figures 35 and 36
).
To estimate how much thread is on a bobbin, place
a full bobbin in the machine and under the heading
Bobbin Thread Capacity, press the Record button
(
Figure 35
) Quilt as usual.
When the bobbin runs out, press the square Stop
Recording button and note how many yards is indicat-
ed under the Bobbin Thread Capacity (
Figure 36)
, per-
haps 210 yards. Since you want a warning as to when
the bobbin is getting low, use the “-” button to specify
a lower number, such as 195 yards. Save that as one of
the Bobbin Thread Capacity Presets. You might want
to make a note as to which type of thread the preset
represents. Put a new bobbin with the same thread into
the machine and press the New Bobbin button. Then
press the Alarm button. As you quilt, the remaining
bobbin thread value will estimate how much thread re-
mains on the current bobbin, and when you reach the
capacity value, an alarm will sound warning you that
your bobbin is nearly out of thread (
Figure 37
).
When operating in Manual mode, the low bobbin
function assumes you will stitch at approximately the
last SPI setting you had on the regulated screen. If the
SPI setting was below 8 stitches per inch, the function
will assume you will quilt at 10 stitches per inch. It
is advisable therefore to set the stitches per inch that
you will be quilting on the regulated screen before you
change to manual mode.
You can store three Bobbin Thread Capacity preset
values: one for each of three different types of thread.
Simply go through the record process with a full bob-
bin of that type of thread and then store the capacity as
a preset. When you switch to using that type of thread,
press appropriate preset button. Insert a full bobbin
with that type of thread, press New Bobbin, and all of
the settings will be based on that type of thread.
