Hi All,

I am wondering if anyone can tell me if its normal for a new Duet 3 6HC (unconfigured) to turn on the heater outputs automatically when connected to a heater i am only using one output but when the hotend is connected any output's the heater is powered ?

other than that the red status led is off presumably because the circuit is not complete.

no, it is not normal for a heater output to automatically turn on.
Best way to test is to remove the SD card and power the board. If the output comes on, the mosfet has died. If it doesn't, you have an issue with your config.

I am using a PI3 but none the less you theory still works with the pi disconnected and no SD card in the duet i still get power guess its an email to oozenet for a replacement ..
