Error:short-to-ground/over temp shutdown reported by driver 2

@phaedrux Let me know if you need some photos at different angles, I tried to get as close as possible to see the solder points. Is it crucial to mount the board with the plastic washers? I had it out of the case I had it mounted in and I still get the same driver reporting shorted. You can tell the board has been sitting unused with the dust haha. Is there someone in the US or Canada that does repairs?

I don't see any obvious damage.
I think your options are to either disable the driver to silence the warning and use a single driver for the z axis by wiring the steppers up in series. Or adding an external driver. Or replacing the driver chip if that's something in your wheel house.
You could also try contacting roland@duet3d.com to inquire about a possible discounted refurbished unit on exchange.

@phaedrux If I wired the Z motors in series though I wouldn't be able to control bed leveling correct? What would be the cheapest way to add an external driver? I personally don't have the skills to repair/solder that small but would be up for getting it repaired. I messaged two of the USA based people that were on the community repair post. I will email Roland now and see what he says. Thanks for the help!

That's right, independent motor control would not work.
Take a look here for adding an external driver.

@phaedrux Dang didn't really want to spend another $100, yeah I might do the exchange when Roland gets back to my email. Would a Maestro expansion board work as well? Or would the pin setup not work with the Duetwifi2 - V1.02.

Do you mean for adding a Duex? That's not the only option. You can use a Pololu or stepstick style driver as well connected to the expansion header pins.
There's also the expansion breakout board that makes it a bit easier without requiring a full Duex.

@phaedrux Okay that would be a much easier pill to swallow. Does the driver need to match the ones on the board or can it be a newer TMC driver? Unfortunately it looks like single stepsticks are harder to come by on amazon. Any other sources for a TMC stepstick? Thanks again for the help as usual Phaedrux.

@stephen6309 Thanks, I hadn't realized filastruder had them. I assume they don't need to match the other drivers that are on the DuetWifi 2.
