I agree with you that DUET is very advanced. I know that Klipper provides a method dispersed model of printing control of old "specialized" hardware and solid tech of Single Board Computer.

However, at this point this how I feel. Arthur C Clarke meant when he said that any sufficiently advanced technology is indistinguishable from magic. If you show someone something that is so far advanced from the technology that they are used to that nothing about it is remotely familiar then you might as well be showing them a magic box.

I'm trying to understand this magic box.

@gtj0
I hope to have the Raspberry PI always on. It would allow me to view the status of the print before, during and after.

Is this possible?

Option 1 - Raspberry Pi leverages GPIO pins to activate the relay to drive the PSU

Option 2 - Duet handles the power up. I am not sure how that could happen as it would need 5 volt dc power externally.

Hello Duet3d Members,

I am posting for simple and straightforward help. if there is a DUET 3 101/Dummies book please point me to it.

I have to state that my knowledge comes from Marlin, Octoprint and Klipper. I thought it prepared me to take on the DUET world. It is apparent have spoiled with such features a GUI that allows me to power-up/shut the controller board and view the progress of the print jobs. So please help me understand. The DUET 3 seems to have more ways of doing things then Houdini had methods of getting out locks/confinement.

As a Note Why I'm doing this to build a BLV MGN 300x300x640mm unit. It will employ a BLTouch, Sensorless homing and Hemera Volcano Hotend. It has long slog of printing,printing and putting together.

What I'm trying to Understand

1. Want power the DUET and SBC "Raspberry PI 4" separately for the 5 volt source. I have seen to many issues with Pi boards fall over with odd power ups.
2. Control the power supply with a Relay and the DUI interface.
3. View the print on Raspberry PI camera.

How do provide the power to the DUET and support the PSU Relay?

How do you update the DUI to do the power off/on with such features as wait until the system cool enough or simply not doing anything for a given time?

What is current opinion on Camera - User the DUET image or use the current Buster OS then add on to it?
