Updated Sep 10,2025


Overview

The xTool S1 is compatible with two air assist systems:

  1. the Air Assist Set and
  2. the Air-Compress Assist.

This article addresses connection failures between the Air Assist Set and S1, specifically when the xTool Creative Space (XCS) fails to display or enable auto-adjustment options.

❗ For Air-Compress Assist, please refer to: Troubleshoot Air Compress Assist Fails to Connect to S1.

 


Issues description

When the Air Assist Set is in "Auto" mode, the XCS interface should display selectable air assist adjustment options, such as the one in the picture below:


However, if a connection failure occurs, the XCS interface may exhibit one of the following symptoms:

  • The air assist set adjustment options are not displayed.
  • The air assist set adjustment options are displayed, but they are grayed out and unselectable.

 


Possible cause

  1. Outdated S1 firmware version
  2. Air Assist Set connection cable issue
  3. Malfunction of the S1 main control board's accessory port board
  4. Air Assist Set malfunction

 

Troubleshooting procedure

#1 Update S1 firmware

Ensure your S1 firmware is up to date. Firmware version 013 and later addresses this issue.

  1. Connect the S1 to your computer.
  2. Locate the gear icon in XCS.
  3. Navigate to Basic info and check your firmware version.

 


#2 Restart S1

Important: Always connect the Air Assist Set to the S1 when the S1 is powered off. Connecting while the S1 is on may prevent the Air Assist Set from functioning correctly or even damage the main control board.
  1. Power off S1.
  2. Ensure the Air Assist Set and S1 are properly connected.
  3. Power on S1 and observe if the issue is resolved after the restart.

 



#3 Request replacement

If the above steps do not resolve the issue, the issue may to do with the Air Assist Set cable, the main control board's port board or its connection cable. In this case, please contact the xTool official customer service by submitting a ticket on https://support.xtool.com/submit-ticket.
