This article applies to:

xTool S1 with all laser modules and the air assist set.

Issue Description

Should you experience any issues with the air assist set's functionality — for instance, if the adjustment settings do not appear on XCS in auto mode, or if the pump fails to expel air or emits only a feeble airflow — please refer to this guide for instructions.

Troubleshootting

#1 Check the Connection Cable

The air assist set receives power from the machine. The air assist set won't function properly if the connection cable between them is loose or damaged. 

Please check if the connection cable is securely inserted into the port, or try using a different one.

Note: When you connect the air assist set to xTool S1, power off the machine first. Otherwise, hot plugging may cause damage to the main control board.

 

#2 Check the Accessory Ports

Please check the accessory ports on the S1 mainboard for any signs of bending or damage. If found, please get in touch with customer support to arrange for the replacement of the board.

 

#3 Check the Cable Inside the Set

If the air assist set releases little to no air after manually selecting the level, please remove the protective cover from the air assist set. Check if the cable on the main control board of the air assist set is broken. Please follow the instrutions below:

1）Remove the air tube connector on the air pump

 

2）Remove the four screws at the bottom of the pump.

 

3）Pull the bottom cover to reveal the internal circuit board.

 

If the cable of the air assist set is stuck by the board, once the air assist set falls off, it may cause damage to the cable.

• Place the air assist in a stable position to prevent it from falling off.
• Adjust the cable placement to avoid damage from getting stuck.

#4 Check the mainboard of the Set

Connect the adapter of the S1 directly to the mainboard of the air assist set and proceed as follows:

• Check if the power indicator light marked with the number 1 is illuminated. Should it remain unlit, the mainboard is likely defective and requires replacement.
• Set a multimeter to the DC voltage range, and place the red probe on point 2, and the black probe on point 3. If the voltage reading on the mainboard is not 3.3V, the mainboard is faulty and needs to be replaced with a new one.
