1. Test the External Air Pump

• Disconnect the air pump from the machine and plug it directly into a household power strip.
• Turn on the air pump and observe if the airflow alarm still occurs.

A. If the alarm disappears: 

This indicates that the air pump itself is functioning correctly. You will need to update the airflow delay parameters.

LightBurn:

Import the parameter file into LightBurn to upgrade the firmware. File link:

RDworks:

• Locate the “delay after feed” setting.
• Change the value to 4000, 6000, and 8000, respectively.
• Follow the order: Read→ Change Value → Write
• Click ”Read” again to confirm the changes have been successfully updated.

B. If the alarm persists

This indicates that the air pump itself may function improperly.

1. Swap the Air Tubing Ports:

   Disconnect the air tubing from the machine and swap the positions of the ports as illustrated in the diagram.

   

2. Record the Pressure Alarm Display:

   If the alarm still occurs after swapping the ports, immediately record a video of the pressure alarm display inside the left control box after the alarm is triggered. This will help us further diagnose the issue.
