Problem/Symptom
Encoder issue/stitch regulator cable is not connected properly
The Pro-Stitcher stitches, but the stitch lengths
vary and the quilting machine slows down or
even stops in some directions.
The white gears do not engage the blue flexirack
When the quilting machine is pushed by hand,
the horizontal and/or vertical crosshair lines do
not move.
The X- and/or Y-axis gears are only partially engaged
Stitched designs appear jagged or wobbly. The
system may be skipping teeth when running,
resulting in a shifting of the design on the quilt.
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.

Corrective Measure
The problem can be narrowed to a specific encoder
wheel by running the quilting machine manually. Start
the quilting machine from the handlebars in Stitch
Regulated mode and only move the machine left
and right. Then try only moving front and back. If the
quilting machine stops stitching while moving front and
back, then the problem is with the encoder mounted
to the back of the machine. If it stops stitching left
and right then the problem is with the encoder on the
carriage. Make sure the encoder wheels roll on the
tracks when moving the quilting machine and also that
the gray stitch regulator cable is plugged in securely to
the encoders.
Make sure the white gears fully engage the blue rack.
Use the manual engagement/disengagement tool to
adjust if needed. Insert into the hole at the front of the
carriage.
If there is motion in the X-axis (left-right), check
the X-axis gear assembly and make sure nothing is
preventing the assembly from springing downward
and putting pressure on the blue rack. If the motion
is in the Y-axis (front/back), make sure the blue rack
and the white gear are properly aligned and adjust if
necessary by loosening the two Y-axis bracket mounting
screws and shifting the Y-axis bracket left/right and re-
tightening the screws. If the white gear is not pressing
upward enough on the blue rack to fully engage the
gears, it may be necessary to install shim washers
between the quilting machine base-plates and the
Y-axis bracket to drop the bracket a little.
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.
