Unplug both ends of the encoder cable and then plug them back in. If both ends click into place
again, continue to step 6. If one end doesn’t click into place, turn the cable around and plug the
opposite ends into the machine and the encoder.

If the same end of the cable does not click into either the machine or the encoder, the cable
will need to be replaced. If the cable does not click into either the machine or the encoder both
times, then the encoder or machine main board will need to be replaced.

Press the button on the display to start stitching in precise mode. Lift the
encoder wheel
off
the tracks and spin it by hand and observe the needle. If the needle moves normally, check the
encoder spring
and
lock collar
and replace if needed. You may also need to clean the wheel
and tracks.
If the needle seems to hesitate or doesn’t respond while you spin the wheel, continue to the
next step.
