Issue description
Before troubleshooting
Firstly, remove all accessory devices from xTool P2 (e.g., smoke purifier, extended exhaust pipe, extended exhaust fan, etc.), retaining only the exhaust pipe provided with the machine. Process the material again and evaluate smoke evacuation effectiveness.
- Scenario 1: If smoke evacuation remains poor
- Scenario 2: If smoke evacuation improves
Scenario 1: If smoke evacuation remains poor
If the smoke evacuation is still poor after removing the accessory devices, the issue may be related to the settings or the installation of the smoke exhaust fan.
#1 Check the setting
Ensure that the "Exhaust fan" function in the XCS is enabled, as shown below.

#2 Check the smoke exhaust pipe
Ensure that the smoke exhaust pipe is not pressed or bent, hindering proper smoke evacuation.
#3 Check the installation of the fan
Remove the smoke exhaust pipe at the rear plate to observe if the fan is installed correctly.
- The correct installation displays the white sticker outward.
- If not, use the 2.0 mm hex screwdriver to remove the four screws. Take off the fan cover and reinstall the fan.
#4 Check the sponge gasket
Remove the four screws fixing the fan cover and make sure the sponge gasket is placed in the fan cover as shown below.

Scenario 2: If smoke evacuation improves
If the smoke evacuation improves after removing the accessory devices, the issue is related to the used devices.
#1 Check the airflow
- For xTool purifiers, ensure the knob is turned to the maximum position.

#2 Check the filters
Remove all the filters from the purifier and test the smoke evacuation. If it improves without filters, consider replacements.

#3 Check the extended exhaust pipe
Confirm the smoke exhaust pipe isn't pressed, bent, or excessively lengthy for efficient smoke evacuation.
