Is there a way to pause machine for set period of time. Once I activate M3 (spindle) I would machine to stay still for 1 second before going to next G0 location.

Sample:
N01    G00 X20YZ20
N02    G00 X1.1 Y1.1
N03    M03
I would like it pause for 1 second
N04    G00 X1.1 Z1.1

You can set a spindle delay in the ports and pins page in the spindle section that should do that, or you can use G4 P1

Fantastic, thank you!
