BLTouch Duet 2 Wifi didnt work

RobiiinX

Hello, i connect my original BLTouch to my Duet 2 Wifi and changed it in the firmware. But it isnt work. The Pin of the BL didnt get out. But it lights red. But he dont takes his pin out. Do you see the Problem?

It is connected like here:

www.duet3d.dozuki.com/wiki/connecting_a_z_probe

In the Config.g i write:

M307 H3 A-1 C-1 D-1
M558 P9 H5 F100 T2000
G31 X19 Y0 Z0 P25

In deployprobe.g i write:

M280 P3 S10 I1

In retractprobe.g i write:

M280 P3 S90 I1

Anything other i didnt change.

Thank you for help

What firmware version?
Can you please post your full config.g and your homing files?

Also the results of sending M122 and M98 P"config.g"

@robiiinx
Do you have line like

M950 S0 C"exp.heater3"
M558 P9 C"^zprobe.in" H5 F120 T6000

and try use

M280 P0 S10

M280 P0 S90

look on this docs https://docs.duet3d.com/en/User_manual/Connecting_hardware/Z_probe_connecting

I think the issue is that you're using M307 (RRF 2) where you should be using M950 (RRF3)

My working config:

M950 S0 C"exp.heater3"                         ; create servo pin 0 for BLTouch
M558 P9 C"^zprobe.in" H1 F120 T9000            ; set Z probe type to bltouch and the dive height + speeds
G31 P500 X45 Y0 Z2.399                         ; set Z probe trigger value, offset and trigger height

I also have a macro defined for finding the nozzle to probe offset:

G29 S2						;Disable mesh compensation 
G1 X75 Y75 Z10			; change this to a convenient position on your bed
G30 						;Extend probe and touch
G92 Z15						;Allow extra room
M291 S3 Z1 P"Move nozzle to touch bed"	; dialogue to jog nozzle to bed. 
G92 Z0						;set new zero
G1 Z10						;move away
G30 S-1						;see output for offset

You'll need to feed the measurement it prints to console to the Z parameter of G31. Further reading here:

Hopefully that gets you going

@phaedrux said in BLTouch Duet 2 Wifi didnt work:

Also the results of sending M122 and M98 P"config.g"

Please provide this so we can see what firmware version you are using so we know which commands you need to use. Right now you have both commands for RRF2 and RRF3. Most of your config appears to be for RRF3 so I think you should remove these additions.

M307 H3 A-1 C-1 D-1
M558 P9 H5 F100 T2000
G31 X19 Y0 Z0 P25; Custom settings are not defined

But without knowing for certain what firmware you're using I don't know.
