Hi, I have had my Duet WiFi for less than a month. Recently, I have been unable to connect to it in any way. The green LED also does not turn on. No endstops were ever connected. The only things ever plugged into the board were motors, a hotend heater, a thermistor, and an always-on fan.
Thank you in advance for your help.
If the red LED turns on but the green LED doesn't turn on, that suggests a problem with the 3.3V supply. Please communicate with your supplier to get your Duet exchanged.
