In the world of Computer Numerical Control (CNC) machining, the ability to visualize and verify G-code before sending it to a machine is not just a convenience—it is a necessity. A single misplaced coordinate or a forgotten tool offset can result in a ruined workpiece, a broken spindle, or even a dangerous crash. This is where NC viewers become invaluable, and among the many utilities available, has carved out a reputation as a lightweight, efficient, and reliable tool for machinists, hobbyists, and educators.
