G52 Local coordinate shift
Mach3 Mach4 G-code · Mill
Shifts all work coordinates by the given amounts without motion. Good for repeating a feature at another spot.
Format
G52 [X] [Y] [Z] [A]
Addresses
| Address | What it does |
|---|---|
X Y Z A | Shift amount for each axis |
How it works
Modal until G52 X0 Y0 Z0 or reset.
Example program
G0 G20 G90 G54 G17 G40 G49 G80 (SAFE START, INCH)
T1 M6 (TOOL CHANGE)
S6000 M3 (SPINDLE ON)
G43 H1 Z1.0 (LENGTH OFFSET)

The full 9-line example is in the app. Example is in inch. Check offsets and clearances first.
Watch out for
- G52 shifts every fixture offset, not only the active one.
- Mach3 G52 and G92 share the same mechanism. Do not use them together.
- Cancel with G52 X0 Y0 Z0 before the program ends.
