That is for configuring the probe.
To actually probe you use one of the G30 variants.
So which variant did you use?
Thanks.

As you look to be on RRF3
The M558 command switch "probe type" needs to be set to P8 instead of P1
With Duet 3 main board, expansion board or tool board: Connect the VCC, GND and OUT pins of the sensor to 3.3V, GND and IN respectively on an IO probe connector, and select mode 8 in the M558 command. -
okay i did that but my Z0 stays like in the picture after homing again

your surface is reflective and not dull.
that is not good for ir. -
@fcwilt G30 S-1 ?

OK that variant is used to report what the Z trigger height is.
To set the Z=0 datum you want to use just G30.

@fcwilt thank for the respones, i actually do that in my homing file

Place a plain piece of paper on your bed and try testing again. As Veti says, your bed may not be very suitable for an IR sensor.

i think the problem was, that i had the printer right besight a window where a lot of light entered i moved the printer to a darker place and haddent had any further problems

Ah yes, that would definitely do it.
