I bought the Duet 2 WiFi Clone from your Amazon listing.
I have set everything up according to the guide here and at the Duet3d website with new firmware 3.1.1.
When I try to print, the hotend at E0 terminal on the board always has a fault, even after using M303 and M500 command to calibrate and save settings to config-override.g.
The E0 hotend terminal or circuit seems like it may be faulty at the board because my hotend and heater element works perfect with the stock Ender 3 v1.1.4 board yet will not tune after many attempts on the Duet 2 WiFi Clone. In fact I have not been able to get the E0 terminal to output any voltage after the calibration tuning M303/M500 and shutdown and reset of the board.
I want to give good ratings as only the hotend circuit seems faulty and I think most of your boards are working well out in the world so maybe I can return this board for a new one that has a working E0 circuit?
If there is something I have overlooked please let me know.
Thank you in advance.
