I think I have found the answer. I added these 2 lines in the start g-code and it seems that Z is adapting to the height map. I need to do testing / tuning in the coming days, but happy so far.
G29 S1 ;Load the height map from file and activate mesh bed compensation
M376 H5 ;Taper off bed compensation after Hx mm
I want to add a buzzer (a simple piezo) to make a noise for alarms and such when there is an event.
The M300 command sends messages to my phone/ computer but unless I've got the app open at the time I don't hear it. An actual buzzer would work better for me and I'm sure there is a way to attach it to an 3.3V output but I can't see any information on how.
Any suggestions on how to "export" an alarm to a specified io port? I'd like to be able to send a similar alarm for various events, such as filament error, crash detection, print completed.
I have a Duet 3 Mini 5+, firmware 3.4

Great, thanks! I found some through the Duet macros documentation, so I should hopefully be able to work out something from these.
I'm still having problems but this title is now misleading since it is not necessary to set up sensorless homing first so I have started a new thread problems-setting-up-stall-detection
