New duet wifi board; Z driver not working.
I have just set up the board to test all the hardware is working and I can't get a motor running on the z driver. The z driver is also hot to touch while in idle. I have checked motors that work on the x,y,e0,e1 drivers and they don't work on the z driver.
Is there anything else I can check?

are the jumpers installed on the second connector?
yes jumpers are on the zb connector.
It sounds like a faulty driver, but please check the following:
- Does the Z driver chip run hot even with no motor connected?
- Have you checked that the Z motor connector pins on the underside of the Duet are not shorting against anything metallic underneath the Duet?
- When you send M122, what status does it report for driver 2?
@dc42 No shorting, I have it in an abs enclosure bottom half to keep it safe.
The z driver chip was hot even when no motor was connected so I put a small heatsink on it, no improvement.

I am sorry, if the Z driver gets hot with no motor connected to it, and nothing is shorting against the Z motor terminals, then the Z driver has failed. As your board is new and assuming it's a genuine Duet, you are entitled to a replacement under warranty, so please contact your supplier.
