Hello Korum,

Basically what you need is to search for the strings you want in the file.
It’s more a computer programming job than a robot programming job.

Here is an example of how it can be done with a CNC file named Dragon.nc webwiz/530/Dragon.zip

MODULE MainModule
PERS tooldata Crayon:=[TRUE,[[146.384,1.05238,33.398],[0.0155533,0.708021,0.00727686,0.705982]],[1.6,[12.5,0,-50.5],[1,0,0,0],0,0,0.118]];

CONST robtarget Origine_Dragon:=[[235,380,-0.7],[0.000532811,0.999984,0.00545403,-0.000924032],[0,0,-1,0],[9E+09,9E+09,9E+09,9E+09,9E+09,9E+09]];

VAR iodev VariableIodev;
VAR string StringLue := “”;
VAR bool ConversionOK := FALSE;
VAR num X := 0;
VAR num Y := 0;
PROC main()

Open "HOME"File:=“Dragon.nc”, VariableIodevRead;
! Open “/bd0/” File:=“Dragon.nc”, VariableIodev Read; !IF ON ROBOT’S USB FILE
! Open “C:” File:=“Dragon.nc”, VariableIodevRead; !IF ON DISC C: OF VC

!Search and discard until F200. Found
WHILE StringLue <> “F200.” DO
StringLue := ReadStr(VariableIodevdelim:=" 9"RemoveCRDiscardHeaders);
ENDWHILE

!Search and process until G0 found
WHILE StringLue <> “G0” DO

!Lookup for first X thus eliminating Nxxx
StringLue := ReadStr(VariableIodevdelim:="X"RemoveCRDiscardHeaders);

!Lookup for Y, getting the numbers between X and Y
StringLue := ReadStr(VariableIodevdelim:="Y"RemoveCRDiscardHeaders);
ConversionOk:=StrToVal(StringLue,X);

!Lookup for LineFeed, getting the numbers between Y and the EOL.
StringLue := ReadStr(VariableIodevRemoveCR);
ConversionOk:=StrToVal(StringLue,Y);

!Make it’s move with the X and Y Offset + a 25.4 Scalling
MoveJ Offs(Origine_Dragon,25.4X,25.4Y,0), v50, Z1, Crayon;
ENDWHILE

Close VariableIodev;

ENDPROC
ENDMODULE

Hope it helps,

Fine Exambel Jetman but remember G02 G03 G12 and G13. (Full and Half circles)
The exambel only handels lineary movement not Circles

Another tink i saw is that the movement is A’made during the read of file.
I have tried with a program i made with reading from file during movement and is courses stop like fine points. I changed the program to read all target beforre movement.
In painting it will be bad with fien points

Hello Klaus,

The thing is I know nothing about CNC codes! :smile:
I just opened a CNC file and saw the X and Y coordinates and started from there.

My program was reading the file during movment it was not stopping though, it went real smooth. Were you going at speed higher than V50 or doing large movments?. I was using V50 and Z0.
