Low Bobbin
The Quilt Maker Pro 18 Versa includes a
low bobbin alarm to estimate how soon the
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 is used to pull up and tie off when
beginning and ending quilting.
To estimate how much thread is on a bobbin,
place a full bobbin in the machine, press the red
Record button “A” , and quilt as usual.
When the bobbin runs out, press the top left
button to Stop Recording. Note the number that
is indicated under the Bobbin Thread Capacity
“B” . Use the “–” button to reduce the number
by 15 to 20 so the alarm will sound before the
bobbin runs out . Save the reduced number as
one of the Bobbin Thread Capacity Presets “D” .
Make a note as to which type of thread the
preset represents .

BUTTON ICONS:
A = Record/Stop
B = Bobbin Thread Capacity
C = New Bobbin
D = Save Preset
E = Set Alarm
F = Preset Value
Put a new bobbin with the same thread into the machine and press the New Bobbin button
“C”
. Then
press the Alarm button “E”. 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 that the bobbin is nearly out of thread.
When operating in manual mode, the low bobbin function assumes stitching at approximately the last SPI
setting 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, on the regulated
screen before you change to manual mode.
Three Bobbin Thread Capacity preset values can be stored – 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. Press the corresponding preset button “F” , insert a full bobbin with that type of
thread, and press New Bobbin button to start.
