To extend the longevity of the probe, it is retracted with a magneto-pneumatic actuator while not in use. If the probe is not properly deploying or retracting, it may be necessary to adjust the position of the probe retractor.

Confirm Probe Functionality

1. 1. Disconnect shop air from the machine
   2. Via the H-Series web interface, navigate to Dashboard > Machine Movement and select "Home All".
   3. In the Status section of the dashboard, check the leftmost item under Z-Probes. If this item displays as "0" with a grey background, then the probe is deployed and ready for use.
   4. While observing this item, gently touch the probe tip with a pen, pencil, or other lightweight object. The the status should change to "1000" with a red background when the probe is touched.
   5. Remove the object from contact with the probe. The status should return to "0" with a grey background.
   6. If the Z-Probe status changes as described, the probe is appropriately triggering with contact and returning to a ready state after the contact is removed.

Check Probe Retract and Deploy Functionality

1. 1. Reconnect shop air to the machine.
   2. In the Status section of the dashboard, confirm that leftmost item under Z-Probes is still displayed as "0" with a grey background.
   3. At the top of the DWC window, enter the following command and and click "Send"

      M402 P0

   4. If the status of the leftmost item under Z-Probes should changes to 1000 with a red background, the probe was successfully retracted.
      • If the status does not change, proceed to the Probe Does Not Retract section below.
   5. At the top of the DWC window, enter the following command and and click "Send"

      M401 P0

   6. If the status of the leftmost item under Z-Probes returns to 0 with a grey background, the probe was successfully deployed.
      • If the status does not change, proceed to the Probe Does Not Deploy section below.
   7. If the status changes as expected in steps 4 and 6, the probe retract and deploy functionality is working as intended.

Troubleshooting

Probe Does Not Retract

1. Confirm that the machine is connected to dry compressed air at a pressure between 5,860 and 8,273 mbar (85 and 120 psi).
2. Confirm that the solenoid valve for the probe retract cylinder is open.
   1. Open the cabinet on the rear of the machine.
   2. Confirm that the LED associated with the probe retract cylinder is illuminated.
3. Adjust the probe retract cylinder farther into the probe retract housing
   1. Carefully remove the plastic shrouding from the turret to access the rear of the probe assembly.
   2. Loosen the lock nut on the probe retract cylinder to allow the probe retract cylinder to rotate.
   3. While watching the status of the leftmost item under Z-Probes, rotate the probe retract cylinder clockwise to move it further into the probe retract housing. When the status changes, the probe has been retracted.
   4. Re-tighten the lock nut on the probe retract cylinder to secure its position.
   5. Replace the plastic shrouding around the turret.
   6. Return to Check Probe Retract and Deploy Functionality above and proceed with Step 5.

Probe Does Not Deploy

1. Confirm that the solenoid valve for the probe retract cylinder is closed.
   1. Open the cabinet on the rear of the machine.
   2. Confirm that the LED associated with the probe retract cylinder is not illuminated.
2. Adjust the probe retract cylinder farther out of the probe retract housing.
   1. Carefully remove the plastic shrouding from the turret to access the rear of the probe assembly.
   2. Loosen the lock nut on the probe retract cylinder to allow the probe retract cylinder to rotate.
   3. While watching the status of the leftmost item under Z-Probes, rotate the probe retract cylinder counterclockwise to move it farther out of the probe retract housing. When the status changes, the probe has been deployed.
   4. Re-tighten the lock nut on the probe retract cylinder to secure its position.
   5. Replace the plastic shrouding around the turret.
   6. Return to Check Probe Retract and Deploy Functionality above and begin again with Step 1.
