M401 don't deploy the Bltouch

[Émile]

I have a Duet maestro, the firmware version is 2.0

I did the wiring and everything goes well. Motors are moving, limits switch are good, fans are running, bed and extruder are heating. Even the Bltouch is working... but only when I power-up my printer. My probe is deploying and retracting twice at the start but when I send the M401 command the Bltouch is not deploying. The G30 does not work either, it lower the z but the probe is not deployed.

I wired my Bltouch in the probe connector :

thanks for any help

Remove the I1 parameters from the M280 commands in deployprobe.g and retractprobe.g files.

@Émile said in M401 don't deploy the Bltouch:

G31 P500 X40 Y40 Z2.5

If it's still not working after dc42's change, please set P to 25 for
G31 P500 X40 Y40 Z2.5
because in most cases P25 is used for BLtouch, so please set it to
G31 P25 X40 Y40 Z2.5

@dc42

Tanks a lot! It work!
But now when I send G30 the Bltouch don't really trigger. It retract when touching the bed but the z axis don't stop. On the interface the Z-Probe stay 0.

Double check the white wire for continuity.

Also, if you're using firmware 2.0 you should really consider updating to at least 2.05.1.
