A marking device (10) comprises a housing (12) having a handle (16). A frame (20) is pivotally mounted in the housing about a first axis (22). A marking head (40) mounted on the frame for translational movement in the frame by a first motor (84) in a first direction (x) parallel said first axis and spaced therefrom. A second motor (100) is arranged to pivot the frame with respect to the housing about said first axis in a second, substantially orthogonal direction (y). The pin moves in a third orthogonal direction (z). The motors (84, 100) are disposed within the confines of the frame (20) and move on fixed screws (84, 104).
