¶ Problem Description
- The machine is unable to read files from the USB drive.
- The machine is unable to detect the USB drive.
¶ Possible Causes
- There’s something wrong with the USB drive.
- The file system of the USB drive is not FAT32.
- Tool head not recognized.
- The file type on the USB drive is not compatible with the tool head.
¶ Solution
¶ Step 1. Check if the USB drive is faulty
- Insert the USB drive into your computer to confirm if it can be detected.
- Try using a different USB drive to see if the machine can read the files.
¶ Step 2. Check if the USB drive is formatted as FAT32
The machine only supports FAT32 format. If your USB drive is formatted in another file system, it won't be recognized. Try reformatting it to FAT32.
Please note that formatting will erase all data, so make sure to back up your files first. Alternatively, you can use a different USB drive that is already in FAT32 format.

¶ Step 3. Check if the toolhead is properly recognized
If the toolhead isn’t recognized correctly, the files on the USB drive won't be read. Please check the home screen to see if the toolhead is detected and shows a green dot indicator.
