Dwell time: G4

Between two NC blocks, you can interrupt the machining for a defined time by inserting a
separate block with G4; e.g. for relief cutting.
The words with F... or S... are only used in this block for the specified time. Any previously
programmed feedrate F or a spindle speed S remain valid.

programmed via S...).
