Is there a way to use hardware RX/TX pins instead of the USB?

Hello,

Is there a way to use hardware RX/TX pins instead of the USB? I'm not using any other serial devices and would like to control the grblHAL using the RX/TX pins on the board.

Thanks and happy holidays.

Yes, most boards supports that. Comment out USB_SERIAL_CDC in my_machine.h to enable UART comms.

Oh.!! Okay. Thanks! Why didn't I try that already is what I'm wondering.

Thanks!
