@sgk trigger height needs to be a positive value for the IR probe in RepRapFirmware.

thank you for answering me.
when i type g30 s-1 the bed doesn't stop

is normal

@sgk if you have the gantry high enough do that you can trigger the probe by putting your finger under it, can you see that the z probe value on DWC goes up?

Also, what kind of bed material do you use?

@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

@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

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

@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

@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
