Text to gcode converter11/3/2023 So you should now be able to split up and understand the code better, the majority are universal across all, but others are specific to the machine it's coded for, so splitting up has shown that discounting some has left you with 2 G80 and G70 which are specific to which machine this has been produced for, so you may either delete them or change to suitĪ quick look here /docs/html/gcode.html Other commands S = Spindle F = feedrate M3 = start M30 = end program Specific gcodes such as G80 and G70 are profile and finishing cycle commands which may or may not be understood by linuxcnc Now comes an initialisation sequence G00 G17 G90 G40 G49 N1 etc is line numbering, linuxcnc does not use line numbers so they can go ![]() ![]() % is realy just a start and end marker, mostly used on older machines so not needed but does no harm ![]() Understanding each gcode is the key to good programming, either to understand what a cam program has produced, or to hand edit previous code done for another machineĪlso another good tutorial /linuxcnc/g-code/index.htmlīut to look at your example and tear it apart line by line however every vendor can have there own quirks, this is where when gcode if produced, a PostprocessorĬomes in, there are tutorials in the documentation section, and all over the internet, a good book to obtain is CNC Programming Handbook by Peter Smid , You need to look and learn gcode, in the majority of cases it is all the same.
