Low Bobbin
The Janome Quilt Maker Pro 18 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 factors
such as tension, stitches per inch, and how much bobbin
thread you pull up when beginning and ending your
quilting (Figure 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 36),
quilt as usual.
When the bobbin runs out, press the square Stop
Recording button and note the number that is indicated
under the Bobbin Thread Capacity (Figure 36), perhaps
210. Since you want a warning as to when the bobbin
is getting low, use the “-” button to specify a lower
number, such as 195. 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 remains 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 bobbin
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, then press the
Alarm button and all of the settings will be based on that
type of thread.
