Dwell:

Dwell (G4) can be used to program a delay between blocks. A Timed Dwell is a timed stop. An Infinite Dwell is a stop that can be canceled only by pressing START. With a dwell activated, the 3500i halts motions on all axes, but other functions (coolant on/off, spindle control) remain active. Do not program any other commands.

The time countdown is displayed in the Machine Status Area of the Manual Data Input, and Program Run screens.

Select the More Milling button, and then "Dwell" from the pop-up menu.

Conversational format: Dwell 15 (hold for 15 seconds), or Dwell 0 (hold infinitely).

G-code format: G4 T15 (hold for 15 seconds), or G4 T0 (hold infinitely)

It is recommended that the Programmed Stop M-function (M00) be used instead of an infinite dwell.
