Mini height sensor

As explained in the link I posted, you need to delete the deployprobe and retractprobe.g files from your SD card. You can do this from the web interface System Files Editor. Those are sample files that shipped on the SD card with firmware 1.18 and earlier.

G91 ; relative mode
G1 Z4 F200 ; raise head 4mm to ensure it is above the Z probe trigger height
G90 ; back to absolute mode
G1 X100 Y100 F2000 ; put head over the centre of the bed, or wherever you want to probe
G30 ; lower head, stop when probe triggered and set Z to trigger height

M558 P2 should be P1 with the IR sensor, shouldn't it?
-
changed p2 to p1 and no difrance
-
Please follow the commissioning instructions precisely, the section headed "Testing with Duet electronics". Your M558 P parameter was wrong, and so is your G31 P parameter.

did all of that and tested good if mean the paper test and numbers changing 400s to 500s, its working and can calabrate it and works right reading the bed and setting the g31 command.
but any time i have to rehome z it dosnt stop on time even after lights up -
Have you corrected the P parameter in the G31 command your config.g file yet?

G31 P600 X0 Y0 Z2.26 ; Set Z probe trigger value, offset and trigger height
M557 X15:185 Y15:185 S20 ; Define mesh gridya changed the z to 2.26 if that was right place
i thought somthing in hear should state that or be changed to match, or do i get rid of this file also

Testing with Duet electronics
Very first line.
In your config.g file, use probe type P1 in your M558 command and trigger threshold P500 in your G31 command.

k working thank you
; General preferences
