Custom M-Codes in LinuxCNC: The M100 to M199 Setup Guide
LinuxCNC reserves M100 to M199 for your own commands: executable scripts the control runs mid-program. The setup steps, the P and Q words, the gotchas.

HAL vs G-Code Pins in LinuxCNC: Two Layers, Not One
HAL wires the machine's hardware; G-code commands its motion. They meet at named signals, and confusing the two layers is the classic LinuxCNC beginner trap.

O-Word Subroutines in LinuxCNC: Examples and How They Work
LinuxCNC uses O-words, not Fanuc-style M98/M99, for subroutines, loops, and conditionals. Here is how o-sub, o-call, while, and if work, with examples.
