M28 + object models

Aitor

Good morning everyone,

I would like to know if this is possible, I have already tried all the combinations that I have thought of.

This is the macro I am running

Create the preset folders in macros
M470 P "0:/temporal" M28 0:/temporal/con/con
M28 0:/temporal/config.g
M208 S0 X150 Y150 Z150
M208 S0 X{move.axes[0].max} Y150 Z150
M208 S0 X{^move.axes[0].max^} Y150 Z150
M208 S0 X^move.axes[0].max^ Y150 Z150
M208 S0 X "move.axes[0].max" Y150 Z150
M208 S0 X{"^move.axes[0].max^"} Y150 Z150
M208 S0 X{""^move.axes[0].max^""} Y150 Z150
M208 S0 X<move.axes[0].max> Y150 Z150
M208 S0 X^{move.axes[0].max}^ Y150 Z150
M208 S0 X^"{move.axes[0].max}"^ Y150 Z150
M208 S0 Xmove.axes[0].max Y150 Z150
M29
M471 D1 S"/temporal/config.g" T "0:/sys/configTEST.g" M30 0:/temporal/configTEST.g" M30 0:/sys/configTEST.g
M30 0:/temporal

This has been the result logically, but my intention was to have some of them appear as the first line

M208 S0 X150 Y150 Z150      ;this one
M208 S0 X{move.axes[0].max} Y150 Z150
M208 S0 X{^move.axes[0].max^} Y150 Z150
M208 S0 X^move.axes[0].max^ Y150 Z150
M208 S0 X "move.axes[0].max" Y150 Z150
M208 S0 X{"^move.axes[0].max^"} Y150 Z150
M208 S0 X{""^move.axes[0].max^""} Y150 Z150
M208 S0 X<move.axes[0].max> Y150 Z150
M208 S0 X^{move.axes[0].max}^ Y150 Z150
M208 S0 X^"{move.axes[0].max}"^ Y150 Z150
M208 S0 Xmove.axes[0].max Y150 Z150

If this is not currently possible, would it be possible to add it in future versions? The thing is that it seems to me something very interesting, since it would allow to store data or create files automatically with specific values of the machine.

Best regards and thanks

@aitor

So you want the object model values to be evaluated and the resulting command line written to the file?

I think @dc42 would have to respond here as that would require a change in the way M28 works.

I assume this is what @Aitor wants. I have a different mechanism planned to support this:

echo >"0:/temporal/config.g" "M208 S0 X"^{move.axes[0].max}^" Y150 Z150"

I'm glad to hear that as I also have a use for that ability.

@dc42 That's going to be great!

@donstauffer @Aitor @fcwilt see https://duet3d.dozuki.com/Wiki/GCode_Meta_Commands?revisionid=HEAD#Section_Echo_command. This is now implemented in standalone mode and will be in RRF 3.4.0beta3.

Good morning @dc42,

I'm on version 3.3.0, that's why it doesn't work, right?

Anyway I will update as this feature will solve my life.

Thank you very much
