Is this possible/reasonable? D3/SBC/Panel
-
So I'm no newbie to Duet, but I am to this whole SBC thing, and I don't know if what I want to do is reasonable.
I'm planning on building a printer with a D3, Pi4, and a PanelDue, and thanks to my cybersecurity requirements, I either need to ditch the Panel and go to HDMI to access web storage to get my gcode files, or I need a separate PC to do that for me. Also, I'll have a second printer at an offsite facility (same network) that I'd like to be able to check in on with a webcam running off the same Pi4 (USB not Pi camera module). Is this something I can accomplish?

I'm not entirely sure what you're asking, but I'll try to answer what I think you're asking:
Can you run a Duet3 + SBC without the paneldue? YES
Can you run a Duet3 + SBC without a PanelDue and access from another PC? YES
Can you run a Duet3 + SBC + PanelDue (and optionally access from another PC?) YES/YES
(and just to fill in the gap): Can you run a Duet3 with a PanelDue (and no SBC) and optionally access it from another PC? YES/YES.
Can you attach a USB camera to the Pi4 acting as a SBC? YESThe questions about the camera confuse me. It sounds like you are asking if a SBC (Pi4) is attached to the duet3 for printer "A", can it also run a USB webcam for printer "B" that's "offsite." That doesn't make any sense unless you're using some kind of USB over ethernet.
I'll try to answer anyway: Even though the SBC is "dedicated" to running DSF for the attached Duet3, it can still perform other duties. It can run the full version of Chromium on a GUI, and you can attach USB cameras, run software that accesses the cameras, etc.

Basically, printer B will have a USB cam hooked up to the SBC via USB. I want to be able to monitor that cam from the DWC interface remotely. If I forego the PC for accessing this stuff, and instead have a desktop environment on printer A, I want to be able to look at printer B from printer A.
-
I don't see any reason why not. You could attach the camera to the Pi (via USB) and just aim at printer "B." You'd have to run some software that streams (such as mjpeg_streamer) and then you can view the stream from any web browser (including one running on the SBC.)

Ok, good. I just saw posts about people having various issues that seemed like they might impact this setup. Last question for you, should I be powering the pi4 from the duet or from a separate power supply?

For a Pi4, I think the current suggestion is to use a separate power supply. BE SURE TO SET THE JUMPERS ON THE DUET3 PROPERLY!

Using a Pi4 may require a separate power supply for both the Duet and Pi4 due to power draw. The same holds true it using peripherals that draw power via USB.
