BLtouch with Reprap Firmware 3.0

[Adamfilip]

I managed to get it to deploy in tests but when I run homeall
it gets to the point where it centers the head

then it gives me the error
Currently im getting this error
G28 SetPosition called when DDA ring not empty

Hallo, can you over a Macro or a G-Code push the BLTouche Pin in or out.
I have the BLTouch config like you and the BlTouch don´t move the Pin.

I have the BLTouch wired on Heater3 (PIN8) on the Duet Wifi Board.
i take the G-Code to test M401 / M402
or
M280 P3 S10 I1
M280 P3 S160 I1
M280 P3 S120 I1
nothing move it.

With the old Firmeware 2.05 the Pin Move in and out.

Have you also adapted deployprobe.g and retractprobe.g?

[DIY-O-Sphere]

@CupaCabra said in BLtouch with Reprap Firmware 3.0:

M280 P3 S10 I1
M280 P3 S160 I1
M280 P3 S120 I1

Now you have to use
M280 P0 S10
M280 P0 S160
M280 P0 S120

[CupaCabra]

Hello,
yes i have but i don´t now is it right.

deployprobe.g
M280 P3 S10 I1

and in retractprobe.g
M280 P3 S90 I1

i hope there are right

[DIY-O-Sphere]

change P3 to P0 and remove I1

[CupaCabra]

@DIY-O-Sphere
i change the Code in the Config now an test it.

[CupaCabra]

It´works with
M280 P3 S10 ......

thx so lot

[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!

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...

@dc42

The line is there in config

M950 S0 C"exp.heater3" ; create servo pin 0 for BLTouch

Thanks, somehow I missed that.

@DIY-O-Sphere thanks for confirming that.
