  • The first line moves the X & Y axis to 10mm position with retract plane set to 2mm, drilling to Z -8mm, peck of 1mm at 100 mm/minute feedrate and starts drilling.

  • The second line moves X axis to 20mm position and drill a hole as per the same values.

  • The third line moves X axis to 30mm position and drill a hole as per the same values.
