Updated May 14,2025
Updated May 14,2025
Overview
The xTool S1 is compatible with two air assist systems:
the Air Assist Set and
the Air-Compress Assist.
This article addresses connection failures between the Air Compress Assist and S1, specifically when the xTool Creative Space (XCS) fails to display or enable auto-adjustment options.
When the Air-Compress Assist is connected with S1 through Bluetooth or Wi-Fi, XCS interface should display accessory information, such as the one in the picture below:
However, if a connection failure occurs, the XCS interface may exhibit the following symptom:
Air-Compress Assist information is not displayed in XCS under Device settings > Accessory information.
Possible causes
Outdated firmware version
Air-Compress Assist Bluetooth dongle module malfunction
S1 main board accessory interface board failure
Air-Compress Assist unit malfunction
Troubleshooting procedure
#1 Check S1 firmware and plug-in version
Verify that the machine's firmware is up-to-date. Click "Check for updates" to confirm.
Ensure that the machine's plug-in version is greater than or equal to 1.5.57. With your computer connected to the internet, XCS will automatically download the latest plug-in version.
#2 Restart S1 and Air-Compress Assist, and re-pair
Power off both the S1 machine and the Air-Compress Assist 2.0. Then, power them back on and check if the issue is resolved
If the problem persists, use the pin included in the Air-Compress Assist 2.0 packaging to press the Reset button on the Air-Compress Assist to reset it.
If the above steps do not resolve the issue, the issue may to do with the Air-Compress Assist Bluetooth dongle, the main control board's port board or its connection cable.
