Makes sense, yes. Update attached.

Changes:
- always prepare for cutting before defining arc center (CC)

andrew, it works fine, thank you so much!

Can you correct the first 4 lines of the program and post them, so I can update the configuration, thanks.

andrew, I am not shure, it may be perfect as it is, it looks like original TNC145 header syntax, I have to find it out on the machine.

behavior of TNC is perfect with the actual header syntax, moving 3 L X+1,272 Y+0,400 R0 F9999 M13 with holding last Z level, then 4 L Z-0,300 R0 F30 M

to get program input to TNC145 without error. there must be

OK, great. Thanks for the confirmation.

feedrate is set twice in one line is not perfect at the moment (manually edited with no problem)

OK, update attached.

thank you, I've just checked CAM output file, looks perfect, fine! Machine test result will be posted later, an other question, for output file extension *.cnc instead of *.nc how to manage, please?

Add this to your configuration:

Tnc145.prototype.getFileExtensions = function() {
    return ["cnc"];
};

andrew, thank you for your great job, QCADCAM 3.11.0 is fine for me, looks very good in work results!

Good point!

This will be interesting for my TNC 430 to engrave Labels
I try to extend TNC 415 to TNC 430
Extension .cnc to .h no problem!

TrueType etc. is nice with QCad CAM
Normal contours and holes I process with my own software
Is it possible to disable layers, in my case useful for "CAM-Labels" not for the rest! (one complete CAD-file) ?

TOOL CALL with "GRAV" (comes from a Tool table) corrupts the script !
Solution for inserting " ?

is it possible to catch the filename SCHRIFT.DXF or alternativ the name of the Layer to feed the first and last line
to complete the CNC-file?

Yes, simply hide those layers in the layer list (eye icon) before exporting to CAM.

olly wrote:TOOL CALL with "GRAV" (comes from a Tool table) corrupts the script !

Quotes have to be escaped in JavaScript strings:
this.writeLine("TOOL CALL \"GRAV\" Z S2500");

is it possible to catch the filename SCHRIFT.DXF or alternativ the name of the Layer to feed the first and last line
to complete the CNC-file?

File name of exported file: this.fileName
File name of drawing file: this.document.getFileName()
Layer name of current layer:

var entity = this.getEntity();
var layerId = entity.getLayerId();
var layer = this.document.queryLayer(layerId);
var layerName = layer.getName();

Andrew thanks for your hints
one Step is to go

this.writeLine("BEGIN PGM "+this.document.getFileName()+"MM");
here I got NullString

this.writeLine("BEGIN PGM "+this.fileName+"MM");
here the complete path will be returned

OSX 10.11

olly wrote:this.writeLine("BEGIN PGM "+this.document.getFileName()+"MM");

This would indicate that the drawing has not been saved and therefore does not have a file name.

this.writeLine("BEGIN PGM "+this.fileName+"MM");
here the complete path will be returned

Yes. If you need to get the file name only, use new QFileInfo(this.fileName).fileName().
