G0 is a G‑code command that performs a linear rapid move. It moves the print head or bed without extrusion, meaning only positioning moves.

In most 3D‑printer firmwares, G0 behaves exactly like G1, except that it is intended for fast travel moves. The actual speed is limited by:

the F parameter (feedrate)
or the firmware’s internal maximum speeds
