If I open a sketch with Grbl already uploaded to my Arduino Uno board, can I paste my very simple Gcode text file directly into the appropriate place, and expect it to work ?
Is the use of an intervening program like UGS necessary in this instance ?
I'm looking to test the Gcode to steppers work flow by drawing a circle, converting to gcode and saving as an .nc file, then pasting into the sketch.
I'm not yet setting up limit switches, and manually setting the home position.
Everything works separately, but now I need to try hooking it all together !

If You manage to send 100% correct Grbl sentences, it ought to work.
