BLtouch convert settings from 2.X to 3.X, cant get it to work.

brasse

Hey.
Im a bit confused about the new way to set up BLtouch on the new 3.0 firmware, can someone help me to get it right?

Working configuration in 2.03:
config.g
M307 H3 A-1 C-1 D-1 ; Disable the 3th Heater
M558 P9 H5 F500 T4000 X0 Y0 Z1 ; Set Z probe type/mode 5. H=Dive Height. F=Speed the bed moves. BLtouch

retractprobe.g
M280 P3 S90 I1

deployprobe.g
M280 P3 S10 I1

This is config.g (generated from the online config-tool), based from my old config
M950 S0 C"e3heat" ; create servo pin 0 for BLTouch (also tried e1heat as the generation tool suggested)
M558 P9 C"zprobe.in+zprobe.mod" H5 F120 T6000 ; set Z probe type to bltouch and the dive height + speeds

I cant get the probe to deploy/retract (M401,M402) with this config on 3.0, what am i doing wrong?

Best Regards

Your deployprobe.g/retractprobe.g is wrong. The configtool generates this and it should work:

config.g:

M950 S0 C"duex.e3heat"                         ; 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

deployprobe.g

M280 P0 S10 ; deploy BLTouch

retractprobe.g

M280 P0 S90 ; retract BLTouch

It made no difference at all, M401/M402 still does nothing

pipersw

can you post your config.g, deployprobe.g and retractprobe.g ?

don't use pin definition for duex, but try with the extension connector pin number :

M950 S0 C"exp.8"                         ; create servo pin 8  for BLTouch
M558 P9 C"zprobe.in" H5 F120 T6000             ; set Z probe type to bltouch and the dive height + speeds

@pipersw I have tried the configuration i posted in my first post, and i have also tried the config that "chrishamm" posted above.

But i can repeat:
I have tried this:
config.g:

M950 S0 C"duex.e3heat"                         ; 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

deployprobe.g

M280 P0 S10 ; deploy BLTouch

retractprobe.g

M280 P0 S90 ; retract BLTouch

As well as this:
retractprobe.g

M280 P3 S90 I1

deployprobe.g

M280 P3 S10 I1

config.g

M950 S0 C"e3heat" ; create servo pin 0 for BLTouch (also tried e1heat as the generation tool suggested)
M558 P9 C"zprobe.in+zprobe.mod" H5 F120 T6000 ; set Z probe type to bltouch and the dive height + speeds

pipersw

try this :
config.g

; Z-Probe
M950 S0 C"exp.8"                               ; create servo 0 pin 8 for BLTouch
M558 P9 C"zprobe.in+zprobe.mod" F150 H2.5 R0.5 T2000 A10 S0.03 B0  ; set Z probe type to bltouch and the dive height + speeds
G31 P25 X0 Y80 Z1.25                           ; Set Z probe trigger value, offset and trigger height

deployprobe.g

M280 P0 S10  ; set 10deg servo position on GPIO port 0

retractprobe.g

M280 P0 S90  ; set 90deg servo position on GPIO port 0

don't use I1 with M280, and use the same port with M280 as define with M950

@pipersw That did the trick "e3heat" instead of "exp.8" was the main problem. Thanks!
