The reason is that I have an external device which make measure at a certain frame rate and I want to generate the position of each measure that wll be made during milling phase.

Will I be able just by reading the g-code to differentiate a milling phase from a re-positioning ?

And according to your answer considering speed and the device framerate, I could deduce the position (with a error margin coming from the acceleration) ?

Is there case where the position aren't written directly in the G-code ?

Thank for the help.

You can differentiate between when the gcode is makid a rapid repositioning move to when it's milling by looking at the code. Just watch look at the z value. If z is lower than stock its milling. But it's pretty hard to keep up with at 100% speed so you use the back plotted window in your control software. Rapids show up as a different colour line.
