Hi,I'm JJ. From Taiwan. So English is not good enough.
I will try let every one to know what my issue so far.

I use the SD-image/sys-MiniKoseel profile to edit.
But I'm get stuck. here is I edit part as photo.
My motor is 0.9 degree.

I use omron optical endstop F type.
Black wire : signal
Brown wire : 5V
Blue wire : GND

So i just don't know how it hit the plate can't be triggered and rise the nozzle.
It always hit the glass plate hardly. Looks like the board can't read the triggered signal.
Here is the video：

So if u need more info just ask. Thank your time and help.

Are you using a deployable probe? If not… Delete deployprobe macros from sys folder.

deleted it. still same issue. now the nozzle go straight to hit plate.
the optical endstop still can't sent the triggered signal to Duetwifi.
Thank you a lot.

Does the reading in the Z probe box in Duet Web control change when the probe triggers and the LED turns on?

How did you connect the sensor to the Duet, and what M558 command do you have in config.g ?

I already tried M558 mode 1 and mode 4. It looks like same problem.
But now is :
; Z probe and compensation definition
;*** If you have a switch instead of an IR probe, change P1 to P4 in the following M558 command
M558 P1 X1 Y1 Z1 H3 F300 T12000 ; Z probe is an IR probe and is not used for homing any axes
G31 X0 Y0 Z4.80 P500 ; Set the zprobe height and threshold (put your own values here)

here is my Atom marlin firmware setting . the endstop setting.

should be i done some dumb things.
Still thanks a lot. and sorry my English.

If your probe is causing the endstop LED to turn on when it is triggered, then it has an active low output and you need to add parameter I1 to the M558 command.

Also you should use X0 Y0 in that command and not X1 Y1, unless you are using the Z probe for doing X and Y homing too.

Now it working good.
But i dont know what's next step after G32 or auto delta calibration .
how to set the correct z-height to print?
Any documentation can read.

I found this and follow it :

here is what i got the message:

The z height is 35, right?
so i edit the config.g. here is what i edit part:

Get the nozzle to grip a piece of paper.

Run G92 Z0
G1 Z5
G30 S-1
G1 Z5
G30 S-1
G1 Z5
G30 S-1

After running the above a few times, make sure you get consistent numbers on the reply from running G30 S-1.

That will be your number you put in here.
