      Hi, I have a BLTouch sensor installed with a Duet Mini 5+ (wifi) board but the probe doesn't react to commands. On startup the probe does the normal deploy retract x2 cycle. However when I send the command M401 the probe does not extend. Likewise if I manually extend the probe and then issue the M402 command the probe does not retract. I configured the probe using the online config tool and selected BLtouch as the endstop type for Z and set it to the corresponding port.

        @spowers which port did you set it to? Because only some are pwm-capable. See https://docs.duet3d.com/User_manual/Connecting_hardware/Z_probe_connecting#wiring-the-bltouch

        Only io1, io2 or io3 on Mini 5+.

          If you're still stuck share your configuration files so we can see your commands. Also share exactly how it's wired up.
