Change M3 / M4 to M106 gcode

[agasevangelos]

Hi is there a way to generate gcode with custom ON/OFF M-code for the laser?
I would like to use the M106 m-codes to run the g-code on a 3dprinter running Marlin.

Thanks

I plan to review much of the GCode generation-optimization algorithm to make it more flexible and configurable (i.e. change the kind of command for laser on/off). In a not too far future I will also add this feature.

As workaround you can save the file and edit it as a text file (find-replace).

I tried that, renaming it to *.gcode from *.nc with all M3 inside replaced with M106 And M5 replaced with M107 still no luck...

What do you mean with no luck? What is the problem?

The the program runs(the steppers) , but it doesn't fire the laser on and off.

Did the issue get resolved by anyone out there?
