G2 performs a clockwise circular or arc movement. It is used to print arcs or circles more smoothly than approximating them with many G1 segments.

{Attention Attention for Klipper users, it is recommended to disable this option. Klipper does not benefit from arc commands, as these are split back into line segments by the firmware. This results in a reduction in surface quality, as line segments are converted into arcs by the slicer and then converted back into line segments by the firmware.}

Two ways to define an arc:

1. Using I/J/K (center‑offset method)

• I = X offset to arc center

• J = Y offset

• K = Z offset

2. Using R (radius method)

• R = radius of the arc
