Is it possible to access the # variables from a macro?

To minimize G Code, I'd like to set a value such as #1 = 1.0 in G code and then have a macro access it.

Example:

Code: Select all

#1 = 1.0
M8000   //macro access user variable 1
M8000
M8000


Instead of:

Code: Select all

M8000 { N1.0 }
M8000 { N1.0 }
M8000 { N1.0 }


Yes, exec.Getvar and exec.Setvar. See Macro_capability_detailed.htm in your UCCNC\Documentation folder for details.

Thanks.

That's what I was thinking, but I've never used getvar/setvar and wasn't sure if their purpose was to set only some UCCNC internal variables.

So these two functions only access the "# internal variables" from #0 to #999 and the documented variables #5060 through #5066?

They can use and access any # variable.
One issue though, is that you don't know which variables are used by UCCNC, or even other running plugins.

It would be nice if CNC Drive could publish a list of used Var #'s.

gerry. same goes for anyone that writes macros.
i usually put a list of var numbers ive used in a macro in the top header now. (so i can cross reference later etc)

These functions work with all the #variables, 0..5999. Reserved are 5060..5066 and 5399. (I've searched the manual for "#".)
