      I have a DUET 3 Mainboard 6XD, it was working fine with YAT which means that I was able to send G-Codes from YAT Serial Terminal, but the next time I tried connecting to YAT, no serial port was being detected, I also checked in the Device Manager but port was not being shown there as well. Also, 3.3V LED is not turned on, does it mean that my board is fried?
