Guys, would you by any chance teach rookie how to understand G-code. I would like to learn and understand what those terms are. I obviously understood:
X2.5 (from top view of cnc machine moving X-Axis {up/down} at 2.5")
Y2.5 (from top view of cnc machine moving Y-Axis at {L/R} 2.5")
Z6 (from side view of cnc machine moving Z- at{up/down} 6")
But the only thing I don't understand is what G0, G1, G90, or whatever the letter and number that comes in first of each line. Perhaps, there are some websites that clearly explain that. Care to help or paste website that you would encourage a rookie to read?
Your help is appreicated.
