xTool S1 with any laser module

Issue description

The G-code file fails to be sent to the machine before the processing can begin. You'll see a pop-up error message that says: "Sending file failed. Please try again later."

Possible causes

• Outdated computer operating system
• Unstable data transmission over Wi-Fi
• Oversized file (G-code larger than 500 MB)
• SD card failure
• Mainboard failure

Solutions

1. Check the computer's operating system version

Check whether your computer's operating system meets the minimum requirements for xTool Studio:

• • Windows: Windows 10 (64-bit) or later
  • macOS: macOS 10.15 or later

If your computer's operating system does not meet the requirements, use a computer that meets the system requirements for xTool Studio or upgrade the operating system.

2. Switch to a USB connection

Data transmission over Wi-Fi may become unstable due to fluctuations in the Wi-Fi signal. If the file fails to send, connect your computer to the S1 using a USB cable, and then try sending the file again.

If the file can be sent successfully over USB, the issue is likely related to the Wi-Fi network. Check the Wi-Fi signal from your router or use a USB connection when transferring large files.

3. Test with another file

If the G-code file is larger than 500 MB, the transfer may take longer and is more likely to fail. Connect the machine via USB and try sending another smaller file for testing, such as one of the built-in designs in xTool Studio.

• If another file can be sent successfully, the original file may be too large or contain data issues. Try simplifying the design or splitting it into multiple files before sending it again.
• If the issue occurs only with a specific complex file, provide the project file to xTool Support team for further analysis.

4. Check the mainboard type

First, check whether the S1 mainboard has an SD card slot.

Case 1: The mainboard has an SD card slot

1. Reinsert the SD card
   Refer to the following video: Replace the SD Card for xTool S1.
   With the machine powered off, remove the SD card and insert it again to check whether poor contact is causing the issue.
2. Check the SD card specifications
3. • The SD card must be formatted as FAT32 and have a capacity of less than 32 GB.
   • Third-party SD cards that have not been tested may not be compatible with the machine.
3. Replace the SD card
   If the issue persists, contact the xTool Support team for a replacement SD card. We do not recommend purchasing and using a third-party SD card.

Case 2: The mainboard does not have an SD card slot

If the mainboard does not have an SD card slot (newer S1 mainboards do not have an SD card slot), try restarting the machine.

If the issue persists after restarting the machine, contact xTool Support team. A mainboard replacement may be provided depending on the diagnosis.
