NC/ GCode question for milling
I have used carbide copper to output gcode for milling pcb from an eagle cad drawing. It has everything in there and looks great in an nc viewer, but when I open in boxzy interface, only the plunge and retractions show up, all of the actual contours for milling are omitted. I am a complete novice when it comes to gcode and nc, but after looking at a gcode that works properly and comparing, I noticed that in a functional gcode, there is a "G01 " before each contour (i.e."G01 X3.123 Y4.512"), and in my carbide copper nc file, that G01 at the start of each line is omitted (i.e "X3.123 Y4.512") and when I manually enter that G01 at the start of each line, the contours begin to show up. So my question is this, is there an easy way to append that G01 to the start of each relevant line? My program is something like 8000 lines of code so going through line by line seems not only tedious, but prone to errors, not to mention if I need to re-output my program if I made things too tight or something the first time around.
Is this a good question?
