G10 Set offsets from the program
Mach3 Mach4 G-code · Mill
Writes tool or work offsets from the program. L1 sets a tool offset, L2 sets a fixture offset G54 to G59 and up, and L20 sets the Mach4 G54.1 offsets.
Format
G10 L1 P [Z] [W] [D] [R] or G10 L2 P [X] [Y] [Z] [A] or G10 L20 P [X] [Y] [Z]
Addresses
| Address | What it does |
|---|---|
L1 | Tool offset, P is the tool offset number |
L2 | Fixture offset, P1 is G54 to P6 is G59 |
L20 | Mach4 G54.1 offset, P1 to P248 |
Z W D R | Mach4 tool height, height wear, diameter, diameter wear |
X Y Z A B C | Offset values in machine coordinates |
How it works
Non modal.
Example program
G0 G20 G90 G54 G17 G40 G49 G80 (SAFE START, INCH)
G10 L2 P1 X-12.5 Y-8.25 Z-3.1 (SET G54 IN MACHINE COORDS)
G10 L1 P5 Z1.5 (MACH4 TOOL 5 HEIGHT 1.5)
G91 (INCREMENTAL, ADD TO OFFSET)
…
G10 L2 P1 X-12.5 Y-8.25 Z-3.1 (SET G54 IN MACHINE COORDS)
G10 L1 P5 Z1.5 (MACH4 TOOL 5 HEIGHT 1.5)
G91 (INCREMENTAL, ADD TO OFFSET)
…
The full 7-line example is in the app. Example is in inch. Check offsets and clearances first.
Watch out for
- Mach4 in G91 adds the values to the offset. In G90 it overwrites. A G91 left on turns a set into an add.
- Mach3 G10 L1 takes P X Z and A for tip radius. It cannot set the tool diameter.
- Mach3 values are not saved for the next session unless the tables are saved on the Tables screen.
