@sgk

what happens if you replace this line

M558 P1 C"^zprobe.in" H5 F200 T9000 I0 R0.5		        ; Set Z probe type mini ir sensor

with this

M558 P1 C"zprobe.in" H5 F120 T6000             ; set Z probe type to unmodulated and the dive height + speeds

@sgk said in sensor ir:

If you can see LEDs on the IR probe turning on/off as you put something in front of the IR sensors BUT the bed does not stop moving I would suspect that the signal out from the IR probe is not getting to the Duet board.

Can you post a picture showing the connector from the IR probe as it is connected to the Duet board?

Thanks.

@fcwilt thanks for help

@sgk

Thanks.

According to the IR sensor documentation when the unit is connected and working you should be able to see the Z probe reading on the DWC change as you try to activate the sensor with something placed in front of the sensor to simulate the IR sensor sensing the bed.

Are you seeing any change in the Z probe reading when you do that?

And the number doesn't change if you put something near the sensor or take that something away?

@sgk

And what does your current M558 command look like?

Thanks.

@sgk here's mine for reference: ( the probe pin has a different name, ignore it)
Did you try P8 as sensor type?

@sgk Just to clarify as I have gone over the post and I cant see your answer... when you turn on the printer and do nothing else, if you place something under the IR sensor does the red LED on the board light up when you get close to the bottom of the board?
