Hi

I use a number of headers in my gcode

this.header = [
"%",
"( CREATED WITH QCAD-CAM )",
"( FILE PATH: [FILEPATH])",
"( FILE NAME: [FILENAME])",
"( DATE/TIME: [DATE_TIME])",
"( CUTTER NUM: [T])",
"( CUTTER DIA: [TD])",
"( CUTTER NOTES: [PROGRAM_NAME])",
"[N] G20 G17 G40 G49 G80 G90 G94",
"[N] G64 P0.001" // tighten tolerance
];

Is there one that will write the filepath and filename for the dxf file that is generating the gcode?

Thanks
Jim

No, I will add those to the next release of GCodeBase.

For now, you can register your own variables:

In the constructor:

Code: Select all

    // register additional variables:
    this.registerVariable("inputFileName",       "INFILENAME",           true,  "",  0);
    this.registerVariable("inputFilePath",       "INFILEPATH",           true,  "",  0);

Add a function writeFile:

Code: Select all

MyPostPRocessor.prototype.writeFile = function(fileName) {
    // initialize additional variables:
    this.inputFilePath = this.cadDocument.getFileName();
    this.inputFileName = new QFileInfo(this.inputFilePath).fileName();

    return GCodeBase.prototype.writeFile.call(this, fileName);
};

This gives you [INFILENAME] and [INFILEPATH].

Sorry Andrew

But as always I am having trouble getting this to work.

Maybe you could take a look?

You have two implementations of LxcncIn.prototype.writeFile. The second one will overwrite the first one:

Code: Select all

// define writeFile:
LxcncIn.prototype.writeFile = function(fileName) { ... };

// define writeFile again, with different contents,  overwriting the first one:
LxcncIn.prototype.writeFile = function(fileName) { ... };

You'll have to combine the contents to get only one writeFile:

Code: Select all

LxcncIn.prototype.writeFile = function(fileName) {
    // init date / time variable:
    var today = new Date();
    this.dateTime = formatDate(today, "dd/MMM/yyyy hh:mm:ss");
    
    // initialize additional variables:
    this.inputFilePath = this.cadDocument.getFileName();
    this.inputFileName = new QFileInfo(this.inputFilePath).fileName();
        
    GCodeIN.prototype.writeFile.call(this, fileName);
};

Andrew

And the error is the operator. If you don't save the file with a name before compiling the gcode you won't get a name in the INFILENAME value.

Its working fine now....

Thanks again
Jim
