Baby Lock Pro-Stitcher BLPS2 Instruction And Reference Manual page 73

Problem/ Symptom
The X and/or Y axis gears are only partially
engaged
Stitched designs appear jagged or wobbly.
With the Pro-Stitcher powered and motors
engaged and enabled (locked in position),
pressing the machine side to side or front to
back allows a little motion but the white gear
does not rotate.
One or more of the pulleys/gears on the X or Y
axis assemblies are loose
Stitched designs appear jagged or wobbly.
With the Pro-Stitcher powered and motors
engaged and enabled (locked in position),
pressing the machine side to side or front to
back allows a little motion and the white gear
does rotate.
Lubrication required between white gears
and blue flexirack
When the Pro-Stitcher carriage levers are engaged
squeaking can be heard as the machine is pushed
or driven.
Positioning a pattern using the Reset Home
button
When the Reset Home button is pressed, the
pattern is not positioned properly.
Corrective Measure
Make sure the quick release levers on the carriage
are allowing the white gears to completely engage
the blue flexirack. If the X-axis lever gets "stuck, "
and does not naturally fully engage without pushing
on the lever, it may be because the X-axis motor
assembly is slightly narrower than the carriage. It
may be necessary to insert a thin washer between
the X-axis assembly bracket and the side(s) of
the carriage. To do this, remove the black screws
that mount the motor assembly to the sides of the
carriage and wedge the washers between the inner
wall of the carriage and the motor assembly bracket.
This should relieve the pressure/bend added to the
motor assembly if it is slightly undersized for the
carriage.
Monitor the motor assembly while engaged and
enabled to determine which gear/pulley is slipping.
It will most likely be either the gear mounted
directly to the motor shaft or the gear mounted
to the shaft that drives the white gear. Use the
appropriate Allen wrench to tighten both set screws
on the gear. The motor gear requires a 1/16" Allen
wrench and the larger gear on the drive axle with the
white gear requires a 5/64" Allen wrench.
Lubricate the teeth of the white plastic gears for both
the X and the Y axes by applying a small amount of
silicone lubricant to the teeth of the white gears. Do
not use a solvent-based or an oil-based lubricant
(such as WD-40 or sewing machine oil) as this will
attract dust and eventually clog the gears.
The Reset Home button is not intended to be used
as a re-positioning tool. Reset Home simply makes
the current needle position match up with the "X=0,
Y=0" point of the pattern. This "0,0" position can
vary from pattern to pattern, so the best way to
reposition is by using the Area or Reposition tools
from the menu.
