Thanks for the help...I actually got it working now. This time I only commented the M558 line out

Close to a year ago I acquired the complete but not working Wanhao Duplicator i3 and subsequently got the Duet 3 Mini 5+ board for it. None of my LCDs would work due to being ST7920 based.

The project gathered dust up until very recently when I decided to get an RPi and run Klipper. A few hiccups along the way but nothing too serious but I do find the 2 Z-axis screws to get out of sync very easily. I got a MicroProbe V2 for more consistent Z-homing but also to allow for auto gantry leveling.

@jay_s_uk
It's plugged into the zstop port.
I thought that the M574 would take care of it

@alankilian

Yes, every time. I tried a normal closed switch now then it shows Z is stopped.

However it still seems to think there is a Z probe as well which is stopped.

How to I get rid of the Z probe altogether?

@fcwilt I took out the lines

; Z-Probe
M558 P8 H0 F120 T6000 ; disable Z probe but set dive height, probe speed and travel speed
M557 X25:185 Y25:185 S30 ; define mesh grid

Still the same M119 result.

What am I missing? I am totally new to RepRap as I have been using Marlin for the past 7 years

@fcwilt No I only have a switch.

and M119 gives me this:
M119 Endstops - X: at min stop, Y: at min stop, Z: not stopped, Z probe: at min stop

Do I actually just have to remove the Z-0Probe "section"

Hi all. I have searched and searched, and unless I am not searching right or missing the right posts I can't find the solution to my specific problem.

I actually have a Fly RRF E3 board but using some the Duet firmware and so on. I followed Teaching Tech's Youtube video and it helped me get past other issues I had at first, as the video explains putting this board on a Prusa (I have a clone) and not an Ender 3.

The Z endstop switch is a plain normally open switch.

I have tried both
M558 P1 H0 F120 T6000
and
M558 P3 H0 F120 T6000

X and Y homes perfectly, Z does move up and down when I move it manually. But Z only lifts when I try to home it. It does not even try to home.

Any help will be highly appreciated as I am getting very frustrated with this board after coming from Marlin

Here is my config.g:
