Arc

Definition

A angle,radius[,heading]

A	Arc command
angle	Range -360 to [+]360. Angle of the arc. -ve moves in a CCW direction and +ve in a CW direction.
radius	Radius of the arc in working units
heading	optional range -360 to [+]360 sets the heading relative to the current heading.

Usage

The arc parameter angle sets the direction of the arc: clockwise is a positive angle and counter clockwise is a negative angle. The radius sets a point to the right or left of the starting point depending on whether the angle is positive or negative. Arc is used to cut material and create G02 and G03 moves when translated to g-code.

Example

In this next example, a jump and cw heading change is made from the origin point. The arc of 360 degrees has the same radius as the jump which puts the start position, a default of x,y coordinate of 0,0 at the center of the circle.
