CNC Router Tips Podcast Season 2 Episode 67:
New G-Code Shortcuts


New G-Code shortcuts that could save you time and improve your workflow. In this episode of the CNC Router Tips Podcast Bill Griggs shares the many new software tools and developments that could change the CNC Game for good.

Recent advances in computer hardware and software are having a rapid impact on how people use their CNC machines. Newer more advance Stepper and servo motors have made the machines more accurate and dependable. While changes in software have made the machines easier to operate.

No software advance has been as rapid as the introduction of AI artificial Intelligence to generate G-Code. Bill discusses his brief experience with AI generated G-Code and what it could mean to you.

Sample of AI Generated G-Code Query

Prompt: write g-code to move a 1/4" bit from the starting point at x0,y0,z1.0 to a relative position +2" in the X direction and +1" in the Y direction. Plunge the bit down to -.25", and climb cut a two inch square. Retract the tool bit to a safe distance and return to the starting point.


Response:

Assuming that the machine is already set up and the workpiece is properly clamped, here is the G-code to move the 1/4" bit from the starting point at x0,y0,z1.0 to a relative position +2" in the X direction and +1" in the Y direction, plunge the bit down to -.25", climb cut a two-inch square, retract the tool bit to a safe distance and return to the starting point.

G90 ; Absolute positioning
G20 ; Units in inches
G0 X2 Y1 Z1.0 ; Move to the starting point at x0,y0,z1.0 to a relative position +2" in the X direction and +1" in the Y direction
G1 Z-0.25 F5 ; Plunge the bit down to -.25" at a feedrate of 5 inches per minute
G1 X2.5 Y1.5 F10 ; Climb cut a two-inch square at a feedrate of 10 inches per minute
G1 X2 Y1 Z1.0 F5 ; Retract the tool bit to a safe distance and return to the starting point


Please note that the feedrates and tool speeds specified in this code are just examples and may need to be adjusted based on the specific characteristics of the machine and the material being cut.
