BLtouch with Reprap Firmware 3.0

[droftarts]

@CupaCabra Great! Please post the 'Z-Probe' section of your config.g to show how you resolved this!

Also, you don't need to unassign the heater channels in RRF3 with M950 H3 C"nil", as they are not assigned by default. Only a few pins are assigned by default, and only need to be unassigned if you use them for something else; see https://duet3d.dozuki.com/Wiki/RepRapFirmware_3_overview#Section_Duet_2_WiFi_Ethernet_and_Duet_2_Maestro

M280 P3 S10 ......

Now I am confused.
You will find exact your configuration in
https://duet3d.dozuki.com/Wiki/Gcode#Section_M280_Set_servo_position

And we have done it succesfully on a buddys wifi exact that way with heater7.
Are you shure you have update to the stable and not to a older beta.
I think there you had to trigger the heater instead of the servo channel.

The beta would explain that too.

[CupaCabra]

so i have change the

deployprobe.g
M280 P3 S10

retractprobe.g
M280 P3 S90

if i test with a Marco file
The pin go´s out with S10 und retract with S90

I think it´s right.

Thanks to this thread I've made progress getting my BLtouch to work. I do have a few questions still.

Basic info:
Duet WiFi 1.02 running RRF3
BLtouch V3.1

The BLtouch is wired as follows:
White Wire (Z signal) = Z Probe IN
Orange (Servo Sig) = Heater3
Red (5v) = +5V
Brown (GND) = GND

Questions (I have googled, but can't find clear answers anywhere):

• When I start the printer, the BLtouch performs a self test. This results in the pin being up, and the red led on the BLtouch being on. Is that correct?
• When I do a M280 P0 S10 the pin drops. The red led is off, but a blue led is on now. Is that correct?
• M280 P0 S10 I1 gives the same result. Is it supposed to work with and without the I1 parameter?
• M280 P0 S90 retracts the pin, the red led is on as well as the blue led. Is that correct?

Thanks in advance!

M280 P0 S10 I1

https://duet3d.dozuki.com/Wiki/RepRapFirmware_3_overview#Section_M280
You can remove the I1
I have the same optical signalling, so everything looks fine...

The line is there in config

Thanks, somehow I missed that.

Hello,
today I tried upgrade firmware on my Duet Wifi from 2.05.1 to 3.01RC6. Upgrade was successfull but unfortunately my BL Touch not work after upgrade.

I connected BL TOUCH according to this manual:
https://betrue3d.dk/bltouch-on-duet-wifi-configuratio-and-usage/

With FW version 2.05.1 BL TOUCH worked OK. I understand that I must edit config.g, deployprobe.g, retractprobe.g and home files. I did it, but BL TOUCH not work. After power on BL TOUCH did self test, but thats all. Commands M401, M402 or M280 from console not work and homez and home all not work too.
