Las ruteadoras CNC chinas suelen usar GRBL, que entiende un conjunto reducido de G-code. Aquí tienes la lista de códigos y cómo leer el programa antes de cortar.
The Shapeoko runs GRBL, and Carbide Create generates a compact G-code set: G0, G1, arcs, and M3 to M5 for the router. Here is the list and how to read it.
GRBL runs a deliberate subset of the standard; LinuxCNC runs a full implementation with extensions. Programs flow down cleanly and up only with care.
GRBL implements a documented subset of standard G-code: full motion and offsets, no canned cycles or macros. The list, the omissions, and what they mean.
GRBL files are the standard core with hobby fingerprints: dense explicit moves, laser S-words, no cycles. The five-pass reading method that makes them transparent.
X-Carve programming starts in Easel and grows into GRBL G-code: what the software hides, when to peek underneath, and the basics that unlock the machine.
A wood router's working M-codes are a short list: M3/M5 spindle, M0 pause, M2/M30 end, and the coolant pair M8/M9, usually rewired to dust collection or air.
GRBL has two different number-1 messages: error:1 is a malformed G-code word, ALARM:1 is a tripped hard limit with position lost. Here is how to fix each.
LightBurn's console is a direct line to your GRBL controller: $$ lists settings, $H homes, $X unlocks, $G shows active modes. Here is the working command set.
In GRBL laser mode, M3 holds constant power while M4 scales power with speed, killing corner burn. Here is when each wins and why laser mode must be on.
GRBL laser G-code is a small, friendly subset: G0/G1 for moves, M3/M4/M5 for the laser, and S for power. Here are simple exercises to learn it by doing.
OpenBuilds machines run GRBL through OpenBuilds CONTROL. The G-code is the standard subset, so practising it here transfers anywhere. Here is what to learn.
A Shapeoko runs a friendly G-code subset through GRBL. Here is what to practice so you can read and tweak the programs your CAM software generates.
