Study notes

G10 L1 P1 Z1.5 sets tool 1 Z offset from the machine origin to 1.5.
G10 L1 P2 R0.015 Q3 sets lathe tool 2 radius to 0.015 and orientation to 3.
The Q word uses the Lathe Tool Orientation diagram for cutter orientation.
A valid G10 L1 rewrites and reloads the tool table for the specified tool.

Safety

It is an error if cutter compensation is on.
It is an error if the P number is unspecified, is not a valid tool number from the tool table, or is 0.
