GRBL vs LinuxCNC G-Code Compatibility, Honestly Compared
GRBL runs a deliberate subset of the standard; LinuxCNC runs a full implementation with extensions. Programs flow down cleanly and up only with care.

Between the Haas Classic control and Next Generation, the G-code barely changed; the interface, features, and capacity did. What carries over, and what is new.
No universal Haas speeds and feeds chart exists, because cutting data belongs to the tool and material, not the machine brand. Two formulas replace the PDF.
Haas VPS turns fill-in templates into ordinary G-code programs. What the system covers, what the output teaches, and why reading it stays your job.
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.
Harvey Tool publishes real per-tool cutting data. Translating a chart row into S and F words takes two formulas and three checks: the full worked path.
Heidenhain controls speak two languages: Klartext, the typed dialogue format, and DIN/ISO G-code. What each is, which jobs favor which, and what transfers.
A CNC control reads one block at a time: parse the words, update modal state, plan the motion ahead, then drive the servos. The full pipeline, demystified.
The programmer-operator pay gap is real but variable: it reflects responsibility and scarcity, not a fixed number. What drives it, and how to climb it.
G-code comments come in two styles: parentheses mid-line and semicolon-to-end-of-line, with dialect rules, no nesting, and a few traps worth knowing.
A macro alarm is a message your own shop wrote: a programmer put that check there deliberately. How to read it, what is safe alone at 3 a.m., what waits.
Editing at the machine is a real skill with a fixed procedure: find the block, understand it in context, change one thing, verify before running. Step by step.
