  • X, Y, Z, A, B Value - specifies the axis you wish to move following the distance to move. The distance value will be the current machine units in use.
  • R Value - This is the retract position in the Z axis. This value must be specified.
  • Q Value - The Q value is peck (incremental) value. A positive non zero Q value must be specified.

  • 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.


INFORMATION: Units are defined as either inches or mm depending on your machines setup or G20 or G21 command in use.
