Grabber/Threadfeed Motor Harness
The grabber/threadfeed motor harness connects the grabber and thread feed stepper motors to the con-
nector socket at location “Grabber/ThrFeed” on the main PCB. The grabber/threadfeed motor harness
has two leads coming off of it, one labeled “THREAD FEED MOTOR” and the other labeled “GRABBER
MOTOR”. These leads connect to the interface cables coming off the respective stepper motors.
Replacement Parts Needed:
• harness, grabber/threadfeed
• twist-lock cable ties (available from most hardware stores in the electrical section)
Replacement Procedures:
1. Turn the machine on.
2. Color change to Needle 1.
3. Turn the machine OFF.
•
CAUTION!! Use extreme care not to drop metallic objects, tools, or other conductive material
on the Main PCB when you have the base cover removed. If you drop such objects on the Main
PCB, it can severely damage the electronics which will be very expensive to repair.
4. Remove the right arm cover, upper arm back cover, and lower arm rear cover.
5. Power down the machine and disconnect the A/C power input cord and the external Ethernet
cable from the back of the machine.
6. Remove cover for the main PCB.
a. Remove the 4 screw(s) that hold the main PCB cover in place.
b. Remove the PCB cover.
•
CAUTION!! Be careful not to drop metallic hardware or tools onto the Main PCB while it is
exposed. Doing so can result in severe damage to the electronics that might be expensive to
repair.
