How to Determine Which Firmware You Need

warning

• Note: As long as you are not using a CAN toolboard, you must choose the USB firmware!!!
• When using a CAN toolboard, the mainboard needs to be flashed with the CAN bridge firmware.
• Using an RS232 toolboard does not require flashing any firmware on the mainboard, but the corresponding toolboard needs to be flashed with RS232 firmware.

• USB Firmware
  • Advantages: The most common connection method in 3D printers, reliable and stable communication.
  • Disadvantages: Multiple USB devices may affect data transmission.
• USB Bridge Firmware
  • Advantages: Can connect multiple devices simultaneously without occupying a USB port. Only required when using a CAN toolboard.
  • Disadvantages: The initial firmware compilation and flashing process can be more cumbersome.
