Second nozzle option problem

Bought a second nozzle kit,and installed it.
Wanted to test, but extruder motor does not run.
Tried switching the stepper driver with X axis. And it runs.
Stepper driver second extruder DOA.

How do a get a replace item.

Double check the orientation of the driver board for the second extruder. It faces the opposite way around to all the rest of the drivers! See this pic:

I would guess it would release the magic smoke if inserted the wrong way around!

I know how it has to be oriented, otherwise my second driver would be dead too, don’t you think :slight_smile:
Other driver doesn’t simply do the job.
think they call that DOA

regards, and thanks for the advise
