G7x and profile in subroutine with parameters

G7x and profile in subroutine with parameters was created by MalteS
Hi,

I'm trying to write a macro for touchy that provides the option to specify the x/z coordinates of the G7x profile on the touchy user interface. 

My initial thought was subroutine nesting but I just found out that I cannot nest subroutines. So this does not work:


Code:
O<g7x_macro> sub O100 SUB ... O100 ENDSUB G71.1 Q100 .... O<g7x_macro> endsub


What works (a bit) is to put the profile subroutine after the main macro (before does not work).

Code:
O<g7x_macro> sub G71.1 Q100 .... O<g7x_macro> endsub O100 SUB ... O100 ENDSUB

But now I struggle with getting parameters to the subroutine. Does anybody have an idea here?

If there is interest. The full code is shown below (bear with me - comments are a mixture of German and English :-):

Code:
O<g7x_macro> sub ; #1 b_Modus                            (todo)  ; #2 ae - Arbeitseingriff (Zustellung)  (0.5mm) ; #3 Feed per revolution                (0.1mm/u) ; #4 Surface speed (vc)                 (50m/min) ; #5 Max RPM                            (1400) ; Set default values O100 IF  [#2 EQ 0]     #2 = 0.5 O100 ENDIF O101 IF  [#3 EQ 0]     #3 = 0.1 O101 ENDIF O102 IF  [#4 EQ 0]     #4 = 50 O102 ENDIF O103 IF  [#5 EQ 0]     #5 = 1400 O103 ENDIF (Allgemeiner Header) G8 ; Lathe Diameter Mode G18 ; XZ Plane G21 ; Metric Units G90 ; Absolute Distance (Spindle Steuerung) G96 D#5 S#4 ; Constant Surface Speed Mode M3 G95 F#3 ; Feed-Per-Rev Mode G4 P.2        ; Wait to reach speed (Anfangspositionen merken) #<x_start> = #<_x> #<z_start> = #<_z> G71.1 Q100 D[#2 / 2] I#2 G70   Q100 D[#2 / 2] M5 M2 O<g7x_macro> endsub O100 SUB   G0 X5 Z0   G0 x5 z-11.5   G0 x10 Z-14 O100 ENDSUB %

M2 should always be outside a subroutine, so place M2 after each endsub, and your construct should work.
As you can only use 2 variables, and there is no option to enter a global variable in MDI, it will be difficult to bring the values to your code.
The contur o100sub is in the macro file. If you keep it like that, you need to modify in the macrofile anyway. how about use the default values #3 #4 #5 as this might not change often, only submit #1 and #2 as variable.

Thanks. I'm calling this subroutine as a macro from Touchy . M2 must be inside the subroutine. There is no other GCode executed in Touchy.

I solved the variable problem in the meantime by copying the subroutine arguments to global variables. I consider this ugly as s**t but it gets the job done.
I then ran into the issue that Touchy has limited space for Macro arguments on the UI and no option to scroll through the argument list. This effectively limits the UI to enter 4 (maybe 5) points. This significantly limits the usefulness. Probably not an issue on a bigger screen but is a problem on the 1024x600 pixels display that I use.

Full program is copied below should this be of use to anybody.
