Thank you. M997 did the trick.

I haven't updated since last January... so to be safe, I choose to preserve my old SDCARD and start fresh.

Loaded the latest duetpi, flashed it to the card
enabled wifi, created /boot/sh
booted (... worked! )
apt update
apt upgrade
reboot

Ok... all up and happy. I then used the latest(?) RRF Config tool and sketched out an initial config.g file. This file is far from right... but is intended as a starter.

After a boot, I get a ton of errors... apparently from the firmware. The versions both seem to be 3.1.1.... so not sure why this is happening. Suggestions?

M950 S0 C"io7.out" ; create servo pin 0 for BLTouch
M558 P9 C"io7.in" H10 F120 T3600 ; set Z probe type to bltouch and the dive height + speeds

These suggestions have been good. I'm able to send commands now and get the probe to deploy/test/retract. I'm still getting a flashing indication during homing and homing is failing. Working the issue.

@bjbeare To be clear... I am using Duet3 6HC.

bjbeare

Using the wiki page https://duet3d.dozuki.com/Wiki/Connecting_a_Z_probe, I have connected my bltouch on IO_7 connector: io7.in, io7.out, gnd (black and brown), 5v. For software, I used the configuration tool and set: Input Pin io7.in, Modulation Pin io7.out, PWM Control Channel (OUT7). I also set endstop to z-probe, bltouch.

I suspect that the PWM control channel OUT7 is incorrect. It seems that the schematic isn't released yet... but my guess is that one of the PWM pins has an optional output on io7.out. Is that right? Which one?

Love to get the schematic so that I can figure these things out for myself :).
Could you update the wiki page to provide this info?

Thank you,
Bruce
