Hi. But it probably failed. I configured Marlin in Visual Studio Code on S6 v2.0, connected BOT0 3.3V on the board and recorded on the board. I took out the jumper on BOT0 (without the BOT0 connection it reports to me a broken USB, and Marlin can't even load it with SD card) Visual Studio Code showed a message that everything is fine but if I try to connect the board to Pronterface it doesn't work and it gives me an error : Could not connect to COM5 at baudrate 115200:Serial error: could not open port 'COM5': FileNotFoundError (2, 'The system cannot find the file specified.', None, 2) What about the problem?
