Please if anyone can help. I would like to look at the GRBL prog. and get some gcodes built before the machine turns up anyone know how I can install GRBL with out a driver board for Arduino to take values from including a coms port to see please?
thank you springbird
Just upload it on a uno.
As zwieblum says.
A GRBL controller program will send the G-CODE to the board and even without the actual divers / shield, the UNO will still interpret the code and pass a valid result back to the g-code sending program.
It is not your best way of checking g-code as there are a few better option even online g-code simulators.
For the best results use the MACH2 or MACH3 format of g-code as you may run into some minor issues using other g-code formats (yes there are a few).

I prefer http://linuxcnc.org. It comes with a built in gcode preview
