# LinuxCNC G10 L0 Reload Tool Table Data

Instructions · `G10 L0` · verification: source checked

G10 L0 is a LinuxCNC G-code that reloads all tool table data. It requires that no tool is currently loaded in the spindle. When executed, tool parameters #5401-#5413 update immediately, altered tool diameters apply to later G41/G42 cutter radius compensation, and existing G43 tool length compensation values remain in effect until updated by a new G43 command.

## Study notes

- G10 L0 reloads all tool table data.
- Tool parameters #5401-#5413 are updated immediately when G10 L0 is used.
- Altered tool diameters are used for subsequent G41/G42 cutter radius compensation commands.
- Existing G43 tool length compensation values remain in effect until updated by new G43 commands.
