Decoding Custom G-Code: The Ultimate Power-Up for CNC and 3D Printing

If you have spent any time with a 3D printer or a CNC milling machine, you have likely interacted with G-code. It is the fundamental programming language that tells your machine where to move, how fast to travel, how hot to get, and when to start or stop.
