Hello everybody,
I'm working on a homebuild cnc machine.
I used linuxcnc to move my step motor and all is fine.
Now i read about Arduno GRBL.
I don't understand why I need an Arduino to do the job of a parport PC.
There is any reason for that?
Is it only a CAF (Complicazione Affari Semplici = Simple Job Complication)?
Need your opinion.
