Stitch regulation problems can be caused by a number of things symptoms of a stitch regulation problem include:
- Irregular stitch length
- Long Stitches
- Needle hesitation
- Needle staying in quilt
- Tearing Quilt
Troubleshooting and Diagnosis
Troubleshooting a regulation problem is always simplified by identifying which component of the regulation problem is the root cause. To do this, isolate each individual encoder:
A. Ensure that the machine is in REGULATED PRECISION stitch mode
B. Isolate the MACHINE encoder (often called the Y-Axis encoder) by trying to stitch a straight line front to back and back to front.
C. Isolate the carriage encoder (often called the X-axis encoder) by trying to stitch a straight line from left to right and right to left.
D. If the machine is hesitating or otherwise functioning poorly in a given direction, a visual inspection is needed of the offending encoder.
For the encoders to work, they need to be:
A. Plugged into the machine via the encoder cable which is a grey ribbon for legacy machines, and a black cable similar to a headphone cable on Gen. 3 machines.
B. The silver wheel on the encoder must have the rubber O-ring on it.
C. The encoder must have downward spring tension in order to press the wheel against the track.
D. The wheel on the encoder must roll 100% of the time when the machine is moving in the direction that the encoder controls.
E. The encoder cable must be checked for damage, and connections.
Tip: The routing of the cable causing it to get hung up on tracks or other cables and creating regulation problems is a common problem to be aware of.
