G0 is used to position the tool. G0 is expected to be used when not using the tool, but firmware such as Marlin interprets G0 and G1 as the same command.
G1 is used to position the tool at a specific feed rate. The speed (feedrate) can be set with F*feedrate* and E *amount* amount of material can be extruded during the move. The firmware coordinates moves so that the feed rate for each axis and extruder is consistent and predictable. S can be used to check for endstops (S0: check, S1: ignore) but may not be implemented by your firmware.
