¶ Problem Description
- Regardless of whether the enclosure door is closed or not, the screen displays the alert: 'The enclosure door is opened.'
¶ Possible Causes
-
The enclosure door lacks magnets or the magnets have been damaged.
-
The Hall switch behind column 2 (which has the Hall switch) is damaged.
- The Hall switch cable is damaged.
- Enclosure converter is damaged.
¶ Interim measures
Please click on Settings > Enclosure to enable or disable door detection during 3D printing or CNC to enable temporary operations.
Please note that during laser operation, door detection is enabled by default and cannot be disabled at this time.
¶ Solution
¶ Tools and accessories needed
- Multimeter
¶ Operation process
- Use a metal object to touch the area near the door handle and check if it is magnetic.
-
If it is not magnetic, please contact support for the next step; If it is magnetic, proceed to the next step.
-
Check whether the cable connection between the door hall switch and the enclosure converter is good. If there is a problem, please reconnect or repair it.
-
When the machine is powered on and the enclosure door is closed, use a multimeter to measure the voltage of the connector near the door Hall sensor (attached figure).
-
If the voltage between 5V and GND is normal (voltage value is 5V), please proceed to step 6; if the voltage between 5V and GND is abnormal, please proceed to step 7.
-
Measure the voltage between hall1 and GND or hall2 and GND with a multimeter. When the door is closed, the voltage value should be 0V. Then gently open the door and the voltage value should be 5V. If there is a problem, please get in touch with support to replace the door hall switch and short cable.
-
Measure the conduction of the Hall sensor cable with a multimeter. If there is no problem, contact support to replace the enclosure converter.
