Where can I find RRF3.0 Object Model reference material?

SteveYYC

Is there a reference somewhere I can refer too or is the Object Model currently undocumented?

The GCode Meta Command example references :

machine.autocal.stddev

and earlier on the page :

G1 X{Move.Axes[0].Max-10} Y{Move.Axes[1].Min+10}

so that's two more:

Move.Axes[n].Max 
Move.Axes[n].Min

Is there a complete or semi-complete list somewhere?
The first example is all lower-case and the second is mixed-case. Are the names case sensitive?

The only real reference for the Object Model right now is the model itself. You can get it
at http://<duetpi>/machine/status

If you have json_pp or json_reformat installed, the following will get you a better formatted document
curl http://<duetpi>/machine/status | json_pp

Beware though, it is still incomplete in places.

Alternatively you can clone https://github.com/chrishamm/DuetSoftwareFramework to your PC, then open file docs/index.html in your browser.

Yet another way: below I have pasted a sample output from M408 P1 with no filter. Paste it into an online JSON reformatter such as http://jsonviewer.stack.hu/ or https://codebeautify.org/jsonviewer.

Some of the fields will change, for example MainBoard will be replaced by Boards[0].
