Hopefully the last update. I've received the replacement for the replacement. Motor drivers tested as good for all six drivers. Serial number is 413XX.
Big thanks to Filastruder and Duet for promptly dealing with the issues.

Replacement board has short to ground issues on all 6 drivers. Serial for original was WD416XX, serial for replacement is WD414XX. The diode codes have also been verified as KAXS4.
Email sent to info@duet3d.com with full details.
T3P3Tony, thanks for letting me know regarding potential issues with the SPI bus. I have contacted the reseller and asked for a warranty replacement and referred to this thread. I will mark this thread as resolved once I hear back from the reseller and the replacement process has started.
Cheers
I just purchased my second duet 3 and received it today. When I went to install/configure the board I ran into multiple short to ground faults on drivers 0 2. I then tested all the other drivers and received short to ground faults on all other drivers except driver 1.
I've run multiple diagnostics but I am out of ideas, so please let me know your thoughts or if there is some other way I should test things.
Things I've done:
Updated firmware to current 3.1.1
Tested nema17 motor and cabling for correct pin configuration with multimeter (A1,A2,B1,B2), and tested motor on a free driver port of another duet 3 with success. Motor and wiring is good.
Visually inspected board and found no solder shorts, scorch marks or other indication of a visible short on either side of the board.
Tested power supply with multimeter, reads 24.1v. Tested board with 2nd power supply just in case.
Tested board with no nema17 motor attached, still received "short to ground" errors
Tested with microstepping on and off. No change. Stealthchop was never enabled.
Oddly I can't get the drivers to report a temperature. MCU reports temp fine but drivers report a temp of 0c. Examined board and drivers with an infrared thermometer and got between 32 and 36c.
While I don't think its a config.g issue, I set up a new config.g with only an x axis to test drivers one at a time (with power down when unplugging motors).

Setup for testing:
SBC mode with raspberry pi 4
motor attached (verified wiring) to appropriate driver. LDO 1.68a motor driven at 1340mah i.e.~80%.
Only config commands changed were M569 P0.D, and M584 X0.D (with D being the driver tested).
Only commands issued after start up were M564 H0 to allow movement without homing, and G1 X100 F10000

As I said, anyone with ideas please let me know. I'm assuming this is either a bad board I got, or I'm doing something incredibly stupid.
