So after a couple of prints it looks like -0.25mm is where I want my Z adjust. But how do I keep that without having to adjust it during each print?
Thanks!

In the Duet web interface, go to Settings, then click the System Editor tab. Click on the "config-override.g" file.
You'll have a line that looks something like this:
(this is from my Artemis)
The "H" field defines the max Z height of your machine, as discovered during the probing process.
Since you want the Z height closer by 0.25, You'll increase that H value by 0.25. If I was doing this to my Artemis, the new H value would be 542.995.
Note that you'll have to re-tweak that H value any time you re-run the probing routine as the system will overwrite the config-override.g file.

Re: Quickie: V4 how to keep the live Z adjustment all the time?
Thanks geneb - so once that line is edited, will the Baby Z Steps field on the web interface then go back to 0 or would it just say -0.25 by default when I open it?
Re: Quickie: V4 how to keep the live Z adjustment all the time?
It'll be zero. The "baby steps" field is transient - once you reboot the Duet, it goes away. (You should power cycle the printer after any changes made to config.g or config-override.g.)

The other way to change the Z=0 height is to alter the Z parameter (trigger height) in the G31 command in config.g The advantage of doing it this way is that it will be unaffected by running auto calibration. Increasing the Z parameter (or if it is negative - as with nozzle-contact probes - making it less negative) will move the nozzle closer to the bed.

Thanks that is good to know. Just before trying today's batch of prints I reran Probe Autolevel, but that didn't reset the Z steps in the interface. I adjusted it a little more today as I am trying to eliminate corner warping *and* eliminate elephant foot so it's becoming a delicate balancing act.dc42 wrote: ↑Sun Apr 07, 2019 12:54 pm The other way to change the Z=0 height is to alter the Z parameter (trigger height) in the G31 command in config.g The advantage of doing it this way is that it will be unaffected by running auto calibration.
