@sgk this bed

[oliof]

@sgk pei sheet is semi transparent and I've had mixed success with the IR board on it. I take it you also tested it with the paper underneath?

[A Former User]

@oliof yes yes but the bed does not stop

[jumpedwithbothfeet]

@sgk @oliof, I maybe off base but would it be worth trying the probe in mode 8? this is the way my IR sensor is configured, then use the paper with the bed well out of the way to trigger a response?

I will try

to
M558 P8 C"!zprobe.in" H5 F120 T6000

the bed does not stop

[A Former User]

in fact the probe does not trigger because when I raise the bed I put the finger and the bed does not stop it continues to rise

[jumpedwithbothfeet]

@sgk are you getting any lights on the ir board when the printer turns on, Red light when you trigger it?

[A Former User]

@jumpedwithbothfeet yes 4x

[jumpedwithbothfeet]

@sgk have you read through this?

@jumpedwithbothfeet yes

@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

@siam thank you for helping me

likewise the bed does not stop

@sgk said in sensor ir:

likewise the bed does not stop

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?
