Solved.
I reconfigured the machine as detailed and yes, the configuration was off. I also re-worked the RFF per the delta config as suggested. I didn't change much but tweaks were helpful.
Currently 12 hours of print time on the machine and things appear to be working.
Thanks for the support. It's been clear, instructive, and direct.
Hi there again,
I received the replacement board this afternoon and installed it, taking great pains to ensure I followed the guides. Instead of using the onboard power supply for the 5V - I decided not to tempt fate and use an external 2 wire 5VDC 2A wall plug and moved over the jumper as directed.
All went well and the printer began printing a calibration cube again. I cancelled the print through the web interface knowing the settings in the config file hadn't changed and I had dialed it in before.
Eager to attempt a full print - I loaded a basic file and the board now does very weird things.
Here is the sequence of events that fell afterward:
I ran
M584 - Driver assignments: X2 Y1 Z0 E3, 3 axes visible comes back
M906 - Motor current (mA) - X:1000, Y:1000, Z:1000, E:800, idle factor 30%
M92 - Steps/mm: X: 80.000, Y: 80.000, Z: 80.000, E: 139.560
Don't tell me I've two bad boards in a row...
are there other jumpers or pins I should be checking?
Disappointed.

Hello Sir,
I took a good look at U3 and U2; both do not have visible signs of damage. U3 has all chip markings still clearly visible and U2 is still clear and shiny (no heat damage discoloration).
I put a voltmeter on a 3.3V pinout to ground and measured ~1.3VDC while powered from the USB. I neglected to test with power from mains.
Hi! I'm a new Duet 2 Wifi customer and user. For what I've been able to experience so far, it's a great little board.
I seem to be having some difficulty now. I installed the board on an Openbeam KosselPro and configured it yesterday. I had installed all of the components and had the unit up and running, on wifi, for a single 20mm calibration cube print. Everything calibrated well with the Mini-IR for bed leveling, heated and read temperatures well, and printed solidly with no issue. Best and easiest print I ever completed.
My configuration is:
The challenge comes now where I had the unit turned off for ~14 hours (overnight) and then turned it back on to begin a print. It would not communicate, connect to USB and connect a port, and lost the 3V LED when turned on main power. I used the on board mains power supply for the 5V and 3V supply (default config).
I've disconnected everything, rechecked every connection, followed all the troubleshooting guides.... The PanelDuet powers up too but doesn't connect to the board.
Have you seen this before? Is there something in the diagnostics I've missed? I sense as I've seen in some other posts that it's the 24VDC to 3.3/5V short scenario - but I struggle with how this is possible. All of the connections I've made are new or old dupont style as noted above.
Any assistance you could provide would be appreciated. It looked so promising!
I'd also emailed my vendor (Spool3d) to get some assistance.
Cheers,
Daniel
