G-Code Made Simple: The Ultimate Step-by-Step Guide to CNC Programming, GRBL Setup, Machine Calibration, and Professional Results

By James R. Holloway

Finally - A G-Code Book That Actually Makes Sense
Most CNC guides assume you already know half the material. G-Code Made Simple starts at zero and takes you all the way to writing, editing, and optimizing real programs for real machines - without the jargon walls, without the skipped steps.
Whether you are a hobbyist who just unboxed your first router or a machinist who has been pushing buttons without fully understanding the code underneath, this book gives you the foundation that separates operators from programmers.
Inside this complete CNC programming guide you will find the full G and M code language explained in plain English covering every command you will actually use. You will get GRBL configuration from the ground up including dollar-settings, homing, limit switches, and soft limits. Machine calibration routines cover steps-per-mm, backlash compensation, and axis squaring. Work offset setup using G54 through G59 ensures every job starts in exactly the right place. A feeds and speeds reference covers wood, aluminum, plastic, and steel with a table you will use every week. You will learn how to write G-code programs by hand including blocks, modal codes, arcs, subroutines, and canned cycles. The CAD and CAM workflow chapter takes you from model to toolpath to clean G-code output. A complete job-day checklist eliminates the mistakes that ruin parts. Advanced techniques include probing cycles, parametric programming, and tool length compensation. The troubleshooting chapter addresses the twenty most common CNC errors with specific fixes for each one.
The book also includes five ready-reference appendices: a full G and M code chart, a complete GRBL settings table covering dollar-zero through dollar-132, a feeds and speeds table organized by material, a forty-five term glossary, and a curated resources list.
Compatible with GRBL, Mach3, LinuxCNC, Fanuc, and Haas controllers. The principles transfer directly to any machine you run.
If you have ever stared at a G-code file and felt like you were reading a foreign language, that stops today.
