There is some walk through here (as well as many other things in this guide) which may get you going.

The config part of it is pretty basic though. The main thing we need to know is what pins you are using. Usually it would be pin 3 or pin 7 on the expansion header for the servo control wire.

In config.g

; Z-Probe
M950 S0 C"exp.heater3"                         ; create servo pin 0 for BLTouch
M558 P9 C"^zprobe.in" H5 F120 T6000            ; set Z probe type to bltouch and the dive height + speeds

And then the two deploy and retract files.

@Petar

see my post from above

@Kolbi
i does not say anything about the online config tool

[Phaedrux]

Making those selections should create the config files you need.

The text I showed in my other post is what get generated.

[Petar]

@Phaedrux

thanks
is this all that i have to do or do i have to make some changes in the config file ?

[Veti]

@Petar

the generated files (all of them) are enough if you have set the parameters correctly

@Veti

Thanks i still dont understand why there is not a tutorial like with pictures how to for a noob like thanks again everyone

[Kolbi]

@Petar, sorry - I didn't fully digest your question in that it was pertaining strictly to the online config tool. If you get stuck, give a look at pages 18 and up - these were my lessons learned with getting bltouch operating.

Cheers,
Kolbi

@Kolbi

what do you mean by pages 18 and up ?
do you have a link for me ?
thanks

I also posted a 5 part guide on getting an ender 3 up and running with a maestro on RRF2. It's not exactly the same as the wifi on RRF3 but a lot is applicable.

At some point you'll have to climb the mountain of learning.

@Kolbi
i missed that thanks

[Petar]

@Phaedrux

Ok will read that thanks

[Kolbi]

@Petar, no worries at all. Hope you get it working!

[Petar]

@Kolbi
Yes I hope so too, I am very curious how much better this is than Marlin and the Chinese cheap ass boards
