Hello, i receive my board and look ok, but the firmware on it is not good for me because i need more current on motor and change sensibilyty on driver for the homing, and some minor change, so i compile stock new firmware from PRUSA GitHub and do NO MODIFICATION and compile and flash....no more screen or garbage on screen, baud rate issue, so i grab the FIRMARE.HEX from prusa and the screen is back but with same issue with your firmware about motor current ....i try MARLIN with no issue and everything is ok if i change the board for Einsy RAMBO in config.
So what append about flashing PRUSA firmware, do i need some special library ?. I compile with Arduino IDE and ATOM IDE with same result
Thank you
