BL Firmware

Tip
  • Please note that the bootloader has been pre-flashed at the factory, so there is no need to flash it again.

Entering Flash Mode​

Tip

On the right is the BOOT jumper, and on the left is the RESET button.

  • There are two methods to enter flash mode:
  • Method 1: With the tool board completely powered off, hold down the BOOT button, then connect one end of a data-transfer TYPE-C cable to the mainboard and the other end to your device.
  • Method 2: After connecting one end of a data-transfer TYPE-C cable to the mainboard and the other end to your device, hold down the BOOT button, then press the RST button. Release the RST button, and finally release the BOOT button.

Power Off Operation

Before connecting or re-plugging the USB cable, completely shut down the printer and disconnect other power sources. Do not allow the tool board to be powered simultaneously via the printer's power supply and the USB interface.

USB Connection Compatibility

Some computer USB ports may cause unstable flashing due to driver or signal compatibility issues. If connection fails, try switching to a different USB port on the computer or use a reliable USB hub. If the error shown below appears, check the USB connection and drivers first.
