The AX NPN inductive probe

npm1

Are these type of inductive probes compatible with the duet, I do have BX variant coming in soon.

I know i covered this in a previous post, but that diagram i created didn't work.

I tried all three different diodes on the probe, and yet it seemed as though the signal wasn't being picked up.

So i tracked back to an idea presented on another website where the signal and power(12v) are linked to together using a 10k OHM resistor, and a diode is connected in line with the signal connector.

I gonna try this any way.

But please let me know.

Love the learning curve as i can now solder.

Please provide a link to the datasheet for the inductive sensor that you want to use.

@dc42
detection range: 4mm±10%
set detection: 0~3.6mm
standard detection object: Iron 15×15×1mm
response frequency: DC:0.5Hz AC:25Hz

its a 300ma, NC type of probe

You can use both PNP and NPN inductive sensor with the Duet, see https://duet3d.dozuki.com/Wiki/Connecting_a_Z_probe.

In the M558 command, use I1 if using an NPN output NO or a PNP output NC sensor. Use I0 (or omit the I parameter) if using a NPN output NC or a PNP output NO sensor.

@dc42 OK is omit I0/I1 the same as not including in the line.

I tried that i.e. m558 with the I1 and without it no luck
