Reading analog values from Laser Range Finder (6HC)

[HebigT]

I'm interested in using a non-contact sensor for a metrology-type project in which I 'probe' the surface of a print. The exact sensor is an omron ZX-LD30V from a decommissioned piece of equipment.

I'm using a Duet 3 and it looks like most I/O connections can be set up as Z-probes - does that mean these can be used as analog inputs?

If the omron sensor outputs a 1-5v signal, can I then read these signals into the object model and use them in a macro?

@hebigt Not all input ports are connected to the ADC, see https://docs.duet3d.com/Duet3D_hardware/Duet_3_family/Duet_3_Mainboard_6HC_Hardware_Overview#io-headers. Also note that the ADC expects 3.3V, not 5V, so you may want to add a voltage divider if you need the full output range of your sensor.

Other than that it is perfectly fine to set up an analog Z-probe.

Thanks for that, this is helpful!
