@phaedrux Thanks, the Z axes turned out well.
Now I have the problem that the extruder does not appear in DWG or in the Duet panel

@phaedrux thank you, I see that it is quite simple, I just couldn't find where to start

How to configure two drivers for the Z axis?
I have one motor connected to driver 2. And the other to driver 3

@dc42 Thanks to your technical clarification, I was able to understand more about the problem, and connected the DUET with another cable to port C of my PC, and problem solved. already loaded with BOSSA. And my DUET is working perfectly.

Thanks to everyone who contributed and helped me.

@phaedrux A few months ago on Amazon, I bought it and now I want to use it

@phaedrux

@phaedrux I don't have raspberry pi

I have a duet 3 6HC board. It is new, and when I connect it to the PC, it marks the port as; "device description request error"
DIAG led stays on dim all the time

I have the indicated drivers installed on the PC, I have already followed many procedures, including erasing the memory by bypassing the erase pins.

I already tried with many USB cables, I already used all the ports of the PC. even another PC. and nothing.

I don't know what to do I need help.

@dc42 I have the same problem with the duet 3HC6. And when connecting it to the pc it does not recognize the duet (I already installed drivers) and I followed the procedure that it mentions @Phaedrux
