EMC 10: Grabber Not Home Error

The Grabber Not Home error occurs when the EMC 10 detects that the grabber mechanism has not returned to its home position after a trim cycle. This can be caused by thread remaining in the trimmer system, mechanical binding, alignment issues, or motor-related problems.

Check for Untrimmed Thread

One of the most common causes of this error is thread that was not completely trimmed beneath the needle plate.

If thread remains caught in the trimmer system, the grabber may not be able to fully retract to its home position, causing the error to appear.

Inspect the hook and trimmer area and remove any trapped thread before restarting the machine.

Inspect Grabber Alignment

If the thread has been removed and the error persists, inspect the alignment of the grabber system.

An improperly adjusted grabber assembly can prevent the mechanism from reaching its home position. Refer to the EMC 10 Technical Manual for the proper grabber alignment specifications and adjustment procedures.

Check for Mechanical Binding

If the grabber returns slowly or appears to stick, there may be a mechanical bind within the system.

Power off the machine and manually rotate the grabber limit stop assembly while feeling for resistance or rough movement.

If a bind is detected:

• Remove the necessary covers as described in the Parts Manual.
• Inspect the grabber blade for bends or damage.
• Check nearby covers and components for wear or interference.

Inspect the Grabber Motor Assembly

The grabber motor should operate smoothly throughout its full range of motion.

Using the procedures outlined in the Technical Manual, inspect the motor limit stop assembly and verify smooth operation of the grabber mechanism.

If the motor appears sluggish:

• Inspect the wiring connections at the grabber motor.
• Tighten any loose mounting or terminal screws.
• Retest the system.

Motor or Control Board Failure

If the grabber motor continues to operate slowly after checking the wiring, the motor may require replacement.

If the grabber motor does not operate at all during a trim command or immediate trim function, further diagnosis of the motor control system may be required. This can include inspection of the motor, wiring, or the 4-Axis PCB.

Final Recommendation

After completing these checks, perform several trim cycles to verify that the grabber returns fully to its home position. If the error continues, contact a qualified Melco technician or distributor for additional service and repair assistance.
