I've wrote a little utility (maybe a postprocessor for G-code) expecially suited for maxnc controller.
The utility (improperly called cnctimer is useful to get the execution time of any G-code file.
But it can also change the feed rates, numbering the lines, convert the EAGLE PCB generate files to machineable G-code, and a simple spindle & feed calculator.
I need some help, to test it and to add new features.
It's always free license software, so please get a look at http://cncwiki.eriskouma.com/cncwiki/cnctimer.html.
I'll give it a shot when I get home. Thanks!
