   • Zero the machine: Manually (or automatically if your machine supports it) tell the machine where the X, Y, and Z (top of material) origin points are.
   • Select an appropriate bit (e.g., a 60-degree V-bit for engraving, a 1/8″ end mill for profile cuts).
   • Create an “engraving” or “V-carve” toolpath for your text/design. Set cutting depth (start shallow!).
   • Create a “profile cut” toolpath to cut out the perimeter of your sign, if desired.
   • Simulate the toolpath to visualize the cut and check for errors.
   • Generate the G-code.
4. Run the Job:
   • Load the G-code into your CNC control software.
   • Double-check everything: Clamping, bit in the collet, zero points, safety glasses on.
   • Start the job! Stay attentive to the machine, listen for unusual noises, and be ready to hit the emergency stop.
   • Once finished, remove the sign, and sand off any fuzz or burrs. Apply a finish if desired.
