G53 Move in machine coordinates
Mach3 Mach4 G-code · Mill
A one block move in machine coordinates, ignoring work and length offsets. G53 G0 Z0 is the safe way to send Z home.
Format
G53 G0 [X] [Y] [Z] or G53 G1 X Y Z F
Addresses
| Address | What it does |
|---|---|
X Y Z | Machine position |
How it works
Non modal. Only acts in its own block.
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)
…
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
- Mach3 needs G0 or G1 active and errors with cutter comp on.
- Safer than G28 because there is no intermediate point.
- Machine zero is only right if the machine was homed. On a router without switches it is where you last referenced.
