      Have just disconnected and reconnected my twin Z motors to put into new mounts.

      Now get this error, have checked, there is no short to ground, in fact the opposite, showing, Open Circuit, 3M, 3M, Open on inner Z connector and 3M,O/C,3M,O/C on outer connector.

      Also checked motor, no shorts

        Forget it, sorry, found out it was the cables, I had used two temp cables to test and they were wired differently, even though they were proper stepper cables.

        Additional Q though, if I have two 1.5A motors on the twin Z connectors what is the recommended current setting in config?

          The Z motor connectors are wires in series, so I suggest 1 to 1.2A.

          Sadly different stepper motor manufacturers use different pinouts.
