I don't know what can be wrong, this firmware has been used for thousand of users on the same board without issues. Here are some suggestions:

  1. If you are using a custom display, you can try remapping the serial ports: #define SERIAL_PORT 2, #define SERIAL_PORT_2 -1 . Valid addresses are -1, 0, 1 and 2.
  2. Reinstall the USB driver (Maple) on Windows.
  3. Make sure you don't have any other software hijacking your serial interface (like Cura, Octoprint, etc...)
