G90: Absolute command
G01/G00: Linear interpolation /Positioning
X_ Y_ Z_ A_ B_ C_ U_ V_ W_: Target position to traverse
The absolute command (G90) is the method of commanding the feed position based on the currently set coordinate
system.
The feed end point uses the value calculated from the origin of the currently specified coordinate system, regardless
of where the current position is on the coordinate. The absolute command (G90) is a modal command, and once it is
commanded, it still acts as a valid command unless another position command for the feed target is set.
G90 % Absolute command
G01 X200 Y50 F5000 % Linear interpolation, target position to traverse(X=200, Y=50), speed 5000
X50 Y100 % Linear interpolation, target position to traverse(X=50, Y=100), speed 5000.
The above program represents the movement of the above figure with the G code.
