CNC Button Pusher vs Setup Machinist: The Real Difference
A button pusher loads parts and presses cycle start. A setup machinist owns the offsets, tools, and program. The gap between them is mostly knowing the code.

Do CAM Programmers Need to Know Manual G-code?
Yes. CAM writes most of the code, but programmers still read it daily and hand-edit at the machine. Manual G-code is what separates a setter from a button pusher.

Does Learning G-Code Increase Machinist Salary?
G-code skill alone does not raise pay; the roles it unlocks do. Operators who read and edit programs move up to setup and programming work, which pays more.
