Hi,

This is my first thread and my first DIY router (for a college project).

I'm using the Grbl and RepRap software controllers (not at the same time of course). I intend to modify the code of any of them.

What I need to do is to understand how the program transforms alphanumerical data (g code) into pulses for the stepper drivers. This will give some extra value to my otherwise "copy+paste" project. I'd like to know where are the files I should rewrite.

Is this too difficult to do? What else am I missing?

Thanks in advance!
