Mode

Most G-code commands supported by LC are modal, meaning they put the system into a particular mode of operation and need not be repeated on every program line. A modal command stays in effect until another command changes the mode. Related modal commands that affect one aspect of program execution are called a mode group.

The following list shows the mode groups for G-code commands supported by LC.

Move Mode

G00 Rapid Tool Positioning

G01 Linear Interpolated Cutting Move

G02 Clockwise Circular Cutting Move

G03 Counter Clockwise Circular Cutting Move

Circular Interpolation

G17 XY Plane Selection

G18 XZ Plane Selection

G19 YZ Plane Selection

Units

G20 Inch Units (also G70)

G21 Metric Units (also G71)

Tool Length Compensation

G43 Tool Length Compensation (Plus)

G44 Tool Length Compensation (Minus)

G49 Cancel Tool Length Compensation

Positioning Mode

G90 Absolute Positioning Mode

G91 Incremental Positioning Mode

Miscellaneous Modes using Single Command

G52 Use Local Coordinate System

F Feedrate

Absolute vs. Incremental

All moves are either absolute or incremental. In an absolute move, the ending point is defined relative to a coordinate system origin, usually Program Zero. In
