bltouch config

Petar

Does anyone have a tutorial how to config a bltouch on a duet 2 wifi with the config tool.
I have a ender 3 v2 and im upgrading it like the linear rail full setup.
i cant find nothing on youtube or here on this forum.
I just bought this board and i'm learning how to configure it i have updated the board to 3.11 took me 3 hours to read and how to do it, was a little afraid to brick my board
so does anyone has a link with a tutorial how to or can explain what to select and to add in the firmware if have to.
I found some video's on youtube from a guy ''Design Prototype Test'' but he does not show how to configure the bltouch you have to be a patreon to get it.
hope some one can help me out.

@Petar,
The last few pages of the attached shows how to connect and configure the bltouch. Hope this helps.

select pwm control channel in the i/o mapping

then under endstops you can select the bltouch

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.

Making those selections should create the config files you need.

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

@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

Petar

@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

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

Kolbi

@Petar, my first post had a pdf attached.

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.

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