Issue description

After you have connected xTool P3 to your computer via USB cable, the device name does not appear in the device list under the USB connection option in xTool Studio. Even after you click the Refresh button multiple times, the system continues to display "Device not found".

Potential causes

• A temporary glitch with the device or computer.
• The USB cable is glitching, not original, or connected to the wrong port.
• The computer does not meet the minimum system requirements.
• A USB hub or adapter is causing connection instability.
• Essential software drivers are missing or not installed correctly.
• A VPN, firewall, or antivirus software is blocking the connection.
• The software's plug-in cache is corrupted.
• The device's firmware has an anomaly.
• There is a hardware issue with the internal USB adapter cable.
• Local network permissions are not granted, or duplicated networks are interfering.

Pre-checklist

Before advanced troubleshooting, attempt the following steps:

• Power Cycle the Device: Turn off your xTool device and unplug it from the power source. Wait for 3 minutes before reconnecting the power and turning the device back on.
• Restart Your Computer: Restart your computer and launch xTool Studio.
• Correct Port Connection: Ensure the USB cable is connected to the "USB Connection Port" and not the "Access Control Key Port".

• Use the Correct Software: Ensure you are using the correct software for operation— xTool Studio. xTool P3 does not support xTool Creative Space. To download the correct software, visit the official xTool Studio page: xTool Studio

• • Ensure your operating software is updated to the latest version.

If issues persist after completing these steps, proceed with the detailed troubleshooting procedures in the following section.

General troubleshooting

Step 1: Verify computer specifications

• Check if your device meets the minimum configuration requirements.
• If not, test with a different computer that meets the specifications.

💡 Note: Newly released operating system versions may occasionally have unknown compatibility issues. If you're using the latest OS version and experiencing problems, test with a different computer running a more established OS version.

System Requirements:

Step 2: Check the USB hub & cable (If applicable)

Use the Original Cable

• Connect your xTool device directly to the computer using the original data cable.
• Inspect the cable, especially the connectors, for any damage. See the image below.
• • Replace if damaged, or try another cable if issues persist.
• Note: Some Apple cables or third‑party docks may not support communication.

Verify the USB Hub

• Ensure your USB hub is detected by the computer.
• Test the hub by connecting another device (e.g., a smartphone) and transferring files.

Try Different Ports

• If the connection fails, try plugging your xTool device into another port of your computer.

Bypass the Hub

• If issues persist, connect your xTool device directly to the computer’s USB port with the original cable.
• USB hubs may deliver unstable power, especially when multiple devices are connected.
• Disconnect other devices from the hub while troubleshooting.

Step 3: Check for missing driver

1. In the xTool Studio software interface, click the down arrow in the upper right corner.
2. Select "Settings" from the dropdown menu.
3. In the xTool Studio Settings window, select the "Developer mode" tab.
4. In the "Install driver" section, check if the three necessary drivers (CH340, GD32, RNDIS) are marked as "Installed" (the button will be greyed out).
5. • If any drivers are missing, click the Install button next to the corresponding driver to install it.

Step 4: Check for active VPN

A virtual private network (VPN) can interfere with the printer's connection to your local network.

• Please check if you have a VPN enabled in your computer's settings or if you have any VPN software running. Disable the VPN and try to connect again.
• If no VPN is active, proceed to the next step.

Step 5: Clear plug-in cache

Corrupted cache files can sometimes cause connection issues.

1. In the xTool Studio software interface, click the down arrow in the upper right corner.
2. Select "Settings" from the dropdown menu.
3. In the xTool Studio Settings window, select the "File Setting" tab.
4. In the "Developer mode" section, click the "Clear cache" button next to "Clear plug-in cache".
5. Restart xTool Studio and try connecting again.

Step 6: Check the USB adapter cable

If previous steps haven't resolved the issue, the internal USB adapter cable inside your xTool P3 may be experiencing failure.

Access Internal USB Connection:

1. Remove the left side panel by unscrewing the fixing screws as shown in the reference diagram below.

2. Locate the USB interface connection to the main control board.
   

Test Internal Connection:

1. Check current connection: Verify the USB interface to the main control board adapter cable is properly and securely connected.
2. Direct connection test:
3. 1. Disconnect the USB interface adapter cable from the main control board.
   2. Use a Type-C cable to connect directly to the main control board.
   3. Test the connection with xTool Studio.

Note:
- The port may be covered with a thin layer of yellow soft glue.
- If the connector is difficult to remove, gently clear away the glue with a tool before unplugging.

Interpret Results:

• Works? → The USB adapter cable fails and needs replacement. Contact xTool Customer Service for further assistance.
• Still fails? →The USB adapter cable is not the issue. Proceed to Step 7 and Step 8.

Step 7: Check device startup status

If the direct connection in Step 6 also failed, the device's firmware may be corrupted.

1. Observe Startup Status: With the internal cables reconnected, power on your xTool P3 (you can leave the side panel off for this step). Monitor the startup process for any exceptions:
2. • The laser module should reset properly.
   • The display should show the normal startup sequence.
   • All components should initialize without error messages.
2. If Abnormal Startup Occurs:
3. • The device firmware may be corrupted.
   • Contact xTool Customer Service.
   • Provide the following:
   • • A video recording of the abnormal startup sequence.
     • A video of the main control board indicator lights (visible after removing the side panel in Step 6).

Step 8: Adjust the Flex Cables

If a direct USB connection to the mainboard still fails, or if the USB connection works initially but disconnects after some time, adjust the side camera flex cables.

Operating system-specific troubleshooting

Windows OS specific: Check firewall rules

Windows Firewall might be blocking xTool Studio's communication.

• Temporarily Disable Third-Party Antivirus:
• • If you are using third-party antivirus software (e.g., Norton, McAfee, etc.), temporarily disable it before adjusting firewall settings.
  • This is because antivirus programs often manage firewall rules.
• Open Control Panel: Access the Control Panel (search for it in the Windows Start menu).
• Windows Defender Firewall: Navigate steps-by-steps
• • Win 11: "Control Panel" > "Windows Defender Firewall"
  • Win 10: "Control Panel" > "System and Security" > “Windows Defender Firewall”

• Allow an app...: Click "Allow an app or feature through Windows Defender Firewall" (or a similarly worded option).
• Find and Allow xTool Studio:
• • You might need to click "Change settings" first.
  • Scroll through the list of applications and find "xTool Creative Space" (or a similar entry).
  • Ensure that the checkbox next to "xTool Creative Space" is checked for "Domain", "Private", and "Public" networks (unless you have a specific reason not to allow Public network access).
• Click OK: Click the "OK" button to save the changes.

macOS Specific: Allow xTool Studio local network access

• To enable local network access for xTool Studio, navigate to the Apple menu > System Settings > Privacy & Security > Local Network.
• Locate xTool Studio in the list of applications and ensure the toggle switch is turned ON to allow local network access.

macOS Specific: Remove duplicated "makeblock" networks:

💡 Note
Your xTool device may broadcast a network for connection. As xTool is a brand of Makeblock Co., Ltd., this network name might include "Makeblock." Sometimes, macOS can show duplicated or outdated versions of this network, often with a number at the end (e.g., makeblock-cm 1, makeblock-cm 2). These duplicates can interfere with proper connection and should be removed.

To remove duplicated Makeblock networks with numerical suffixes:

• On your Mac device, choose Apple menu > System Settings, before clicking Network in the left sidebar.

• In your list of Network services, look for any networks named Makeblock that are followed by a space and a number.
• Select the duplicated Makeblock network you wish to remove.
• Delete networks with numerical suffixes, such as:
• • makeblock-cm 1
  • makeblock-cm 2
  • makeblock-cm 3
  • makeblock-cm 4
