BLTouch RRF3

Kiwi3D

Hi team,

Just installed the BL Touch onto my Duet2 Wifi (genuine)

Board is v1.4 running RepRapFirmware for Duet 2 WiFi/Ethernet 3.1.1 (2020-05-19b1)

On power up the probe cycles no issues

On homing the probe does not deploy

All cabling is sound, and has been triple checked

Orange wire is in pin8 on the Exp port (Heater3)

; Z-Probe
M950 S0 C"exp.heater3" ; assign GPIO port 0 to heater3 on expansion connector, servo mode
M558 P9 C"^zprobe.in" H3 F400 R0.2 A5 T10800 ; Set Z probe type to switch and the dive height + speeds
G31 X28 Y5.6 Z1.68 P25 ; Set Z probe trigger value, offset and trigger height
M557 X28:240 Y6:203 P5 ; Define mesh grid

thank in advance

What do you have in your deployprobe.g and retractprobe.g files?

You can test deployment and retraction using M401 and M402.

Does your homeall/homez file use a G30 command to probe the bed or is it configured to use a G1 H1 Z move to seek an endstop?
