Wiring up Duet to turn on an atx psu when pc button is pressed
I was wondering if anyone could offer some guidance, I am contemplating if it is possible to wire up my pc case power button onto the duet wifi, and have it when pressed execute the necessary GCode to turn on the atx psu. I know the duet can already control the psu but I want it to turn on the psu when the pc power button is pressed, from my research I believe it might be possible to use a spare endstop on the board to trigger the necessary GCode. If anyone could help guide me in the changes I would need to make I would be very grateful.
Currently the psu is being controlled by an arduino nano powered by the 5V standby rail which allows the pc power button to work.
CR-10 Heated Bed Wiring
I've just ordered a duet 2 wifi with a 7" paneldue and I'm hoping to upgrade my old CR-10 which has been out of commission for a while. The only thing is that I am going to power the duet 2 from an atx power supply and am unsure how to connect the heated bed. Currently it is going through a mosfet, I have access to two 12v rails both capable of 18A, Is it possible for me to power the duet with one of these rails and keep the external mosfet board powered by the other and therefore powering the heated bed, TL;DR is it possible for me to configure the duet to only send a signal to the mosfet rather than attempting to supply the the necessary current for the bed itself.
Also will I have to supply an additional ground cable to the mosfet? (as it is currently wired) since both the duet signal and the bed will have a common ground in the atx psu.
Thank you in advance for any replies.
