Dudes about Bltouch

Hi,

i am configuring Ratrig printer, and i have isues with Zprobe...
Printer mounts a BlTouch, but when i order the printer Homing, X and Y axis are fine, but Z Duet send a message that are not z probe defined.

When power on the printer, BlTouch do selftest, but when i send macros to deploy, retract and test, do nothing.

a strange thing is that in config.g that Ratrig facilitates for the configuration, for the BLTouch it indicates that you put these lines...

; BLTouch
M950 S0 C"io7.out"                     ; Create a servo pin on io7
M558 P9 C"io7.in" H5 F240 T10800 A5    ; set Z probe type to unmodulated and the dive height + speeds
G31 P25 X-28.00 Y-13.00 Z0.90          ; set Z probe trigger value, offset and trigger height, more Z means closer to the bed

But... Bltouch, its connected to io2

Too add retractprobe.g and deployprobe.g

; deployprobe.g
; Called to deploy a physical Z probe
;
M280 P0 S10															; Deploy the BLTouch pin

and

; retractprobe.g
; Called to retract a physical Z probe
;
M280 P0 S90													; Retract the BLTouch pin

ideas, why not are detected when homing procedure?

one thing more, after start printer and do selftest, BlTouch rest lighted

@peirof

Are you using Duet v3 firmware?

@peirof Change the io7 in M558&M950 to the connections you have, io2.
