The search for a Fanuc VMC code-list PDF usually ends one of two ways: a forty-page anonymous compilation that mixes generations and machines, or this healthier ending: one page, three blocks, printed and annotated, that you can vouch for line by line because you assembled it. Here are the three blocks.
Block one: the G-core a VMC runs daily
| Group | Codes | VMC note |
|---|---|---|
| Motion | G00 / G01 / G02 / G03 | Rapids stay above the work |
| Plane / units / modes | G17, G20/G21, G90/G91 | The header contract |
| Work offsets | G54-G59 | Multi-vise setups live here |
| Tool length comp | G43 / G49 | The VMC’s critical habit |
| Radius comp | G40 / G41 / G42 | With lead-in discipline |
| Drilling cycles | G81 / G82 / G83, G80 to cancel | Modal across positions |
| Returns | G28, G98/G99 | Cycle return planes included |
Two rows carry extra weight on a vertical mill. G43: every tool’s length differs, and the tool-length habit (verify the H number after every change) is the first reflex of safe VMC reading. The cycle row: G81 versus G83 plus their modal behavior and G98/G99 return planes is where hole-heavy VMC work actually lives. Standard meanings check against maintained references; behavior fine print belongs to your control generation’s documentation, navigated the way the parameter-manual guide teaches.
Block two: the M-core
| Group | Codes | Note |
|---|---|---|
| Stops / end | M00 / M01 / M30 | M01 obeys the panel switch |
| Spindle | M03 / M04 / M05 | With S |
| Tool change | M06 | With T; the VMC’s signature M |
| Coolant | M08 / M09 | The switch pair |
| Subprograms | M98 / M99 | Pattern repetition |
Above M30 begins builder territory: chip conveyors, doors, fourth axes, probes, through-spindle coolant, all assigned by whoever built the machine around the Fanuc control, all differing between machines wearing identical control badges. That is not a footnote; it is the third block.
Block three: the ruled blank lines
The defining feature of a code list you can trust is the part you write yourself: a dozen ruled lines under the printed tables, filled by hand from your machine’s own manual (the builder’s, beside the Fanuc set), each entry carrying the code, its meaning, and the machine model it belongs to. This block is why the one-page approach beats every download: provenance per row. The anti-pattern it replaces, anonymous compilations, fails three filters worth remembering: no separation of standard from builder-specific (teaching errors as facts), no control-generation statement (Fanuc meanings shift across series), and no source trail (so a wrong row is undetectable until the machine demonstrates it). The same filters that govern every printed-reference question on this site, the pocket-card pattern included, applied to the VMC case.
Using the page: the two-level rule
Level one, memorized: the core that appears in every program (motion, modes, G54, G43 with its H, spindle, coolant, ends) is reflex material, not lookup material: if the page is consulted for G01, the gap is training, closed the usual free way with 60-second drills on the G-code practice page, G-Code Sprint repeating misses. Level two, consulted: cycle details, comp setup, return planes, and every builder code, which is exactly what the page is for, laminated or taped inside the door, with the reading method supplying the context that makes each lookup land. A page that gets handwriting on it within a month is working; one that stays pristine is decor.
Why “PDF” was the right instinct with the wrong target
The searcher’s instinct (a stable, printable, offline reference at the machine) is correct and professional; only the anonymous-download target fails it. Print this page’s tables, add your machine’s block three, date it, and the result is the PDF that was being searched for, minus the rows nobody can vouch for, plus the only rows that make it yours. Re-verify block three whenever the machine changes or a control board is swapped, the same configuration-truth discipline as parameters themselves.
Bottom line: three blocks, one page, your handwriting
The Fanuc VMC code list worth printing is the standard G-core (G43 habit included), the standard M-core, and ruled lines filled from your machine’s own manual with the model named. Memorize the daily core, consult the rest, refuse anonymous compilations on provenance, and let the page earn its lamination through use.

Frequently asked questions
Where can I get a Fanuc VMC G-codes and M-codes list PDF?
Assemble the one that is actually trustworthy: print this page’s standard G and M tables, then hand-fill ruled lines with your specific machine’s builder codes from its own manual, model name attached. Anonymous downloads fail on provenance: standard mixed with machine-specific, no generation stated, no source trail. For memorizing the daily core, the free G-Code Sprint app is the top pick: 60-second drills with automatic repetition of missed codes.
Which codes on a Fanuc VMC are standard and which are machine-specific?
The motion, mode, offset, compensation, drilling-cycle G-codes and the stop/spindle/tool-change/coolant/subprogram M-codes are standard. Above M30 (and in optional functions) the machine’s builder assigns codes that differ per model: only that machine’s documentation lists them.
Why does G43 get singled out for VMC work?
Because vertical-mill safety hangs on tool length: every tool differs, and a wrong or missing H after a change cuts air or table. Verifying G43’s H at every tool change is the first reading reflex the printed page should reinforce, not replace.
Should I memorize the whole printed list?
No: memorize the every-program core to reflex and consult the rest. The page exists for cycles, comp details, return planes, and builder codes: the two-level split is what makes one page sufficient.
