@sgk

Thank you.

It seems that the IR sensor is working based on the LEDs on it responding to the presence of the bed.

The M558 configuration seems to be correct and if it is in your config.g file it appears to be executing without any problems.

So that really seems to leave only the connection from the IR Sensor output to the Duet Z Probe input.

Do you have a meter of any sort that can verify continuity of the wire from the connector for the IR Sensor all the way to the connector for the Duet Z Probe input?

@fcwilt yes I tested with a multimeter the continuity

OK can you do this:

• Disconnect the connector from the IR Sensor
• Using a small piece of wire or equivalent connect the signal and ground pins of that connector and check the DWC Z probe reading
• Then do the same but connecting the signal and power pins

@sgk I just looked at your config.g what firmware version are you using version 1? it might be an idea to update it!

you can tell me what they are

You said "you can tell me what they are".

I don't know what you mean by that.

OK I will post again my question again:

the probe works but when I do g30 s-1 the bed stays at a great distance from the nozzle as in the photo

@sgk

If you move the bed away from the probe, say to Z=5, does then doing a G30 or a G30 S-1 result in the bed moving and triggering the probe?

the bed remains loing of the nozzle

OK so the probe IS working.

After doing a G30 or a G30 S-1 it is normal for the probe to end up a small distance away from the bed.

That distance is the dive height (the H parameter of M558) plus the Z Trigger Height (the Z parameter of G31).

Does that appear to be what is happening when you do a G30 or G30 S-1?
