Hi,
that sounds unusual.
When the machine homes each axis LED should go from red to green as it is referenced. Does the Z axis LED do so?
The next question is about the Z axis home switch. If you manually flick the switch does the LED for the Z axis (M3Home for example)
show up in the Diagnostics page? When the Z axis is homed the machine should drive until the Z axis switch operates and then back up a little until
it de-operates. Is this what happens? I'm wondering if the home switch does not deactivate then the Z axis may be permanently and repeatedly being
referenced to zero because the home switch is still active.

If I press "Ref Z", the light turns red, Z axis moves up until M3 is triggered, backs off, and then light turns green. After that I have no inputs active and when jogging Z, only "Current Position" updates.
