Enhanced remote jog handle

A computer numerical control machine tool comprising:

• a work tool movable along a plurality of selectable axes of movement;
• and
• a control system including:
• a remote jog handle including a plurality of coaxial rotary knobs configured to control the machine tool, the plurality of coaxial rotary knobs including a first rotary knob deflectable from a neutral position, a second rotary knob and a third rotary knob;
• and
• a controller configured to:
• receive information corresponding to an actuation of the third rotary knob and to output a control signal to select an axis of movement of the work tool from the plurality of selectable axes of movement,
• receive information corresponding to an actuation of the second rotary knob and to output a control signal to control a movement of the work tool in the selected axis of movement in discrete steps, and
• receive information corresponding to an amount of deflection of the first rotary knob from the neutral position and to output a control signal to control a movement of the work tool in the selected axis of movement at a rate corresponding to the amount of deflection of the first rotary knob from the neutral position.
