Issue description
After connecting your xTool Apparel Printer to your computer via USB, the device appears in the "Connect device" list within xTool Creative Space (XCS) or xTool Studio.
However, upon attempting to connect, you receive the following error message even though the status initially showed as "connected": "Connection failed. Please check if the USB connection is stable."
- Consult this content for troubleshooting advice.

Possible causes
- Hardware Replacement Configuration: If the High-speed PCB has been recently replaced, the device Serial Number (SN) data may not yet be synchronized to the new board.
- Outdated Software: The current version of xTool Creative Space or xTool Studio may be outdated.
Troubleshooting Steps
Step 1: Check high-speed PCB replacement history
The most common cause for this specific error is a recent replacement of the High-speed PCB without subsequent SN data synchronization.
- Verify Replacement: Have you or a technician recently replaced the High-speed PCB on this printer?
- Action Required:
- If YES (PCB was replaced): The new board requires remote configuration to write the SN data.
- Take a clear photo of your printer's Serial Number (SN) label (located on the rear panel).
- Contact xTool Customer Service immediately. State that you have replaced the High-speed PCB and cannot connect via USB for a prompt resolution.
- If NO (PCB was NOT replaced): Proceed to Step 2.

Step 2: Update your software
Ensure you are using the latest version of the software. Outdated versions may have compatibility issues with the device drivers.
- Visit the official software download page: xTool Software Downloads
- Compare your current version with the latest version listed on the website.
- If an update is available, download and install it.
- Restart the software and attempt to connect again.
