BTW,

M119
Endstops - X: not stopped, Y: not stopped, Z: not stopped, Z probe: at min stop

So the controller seems to be able to see the sensor when triggered by the bed or metal object.

richardmckenna, how is the BAT43 diode wired into the leads? On the signal lead between the sensor and the controller? Which direction? I am not particularly wise in this area.

I've made some progress thanks to your posts and building a config file as you suggested, DC42, and have got my ANET A8 connected and the end stops are recognized properly including my SN04-N proximity sensor for bed leveling.

All steppers are moving in the correct direction and X and Y axis home properly, but Z axis will not home. When I select "Z axis home" or "all home," the Z axis just moves up about 5cm and stops. It does not lower and stop when the sensor detects the bed.

Any ideas on this Z axis homing issue?

Thank you X4TEC

Thank you dc42. I'll give it a shot.

Anyone configured the Duet 0.8.5 controller with the ANET A8?
