Z-axis setting tool

A Z-axis setting device comprising:

• a housing having a rear wall, a left side wall, a right side wall, a bottom wall, a top wall, a circuit cavity disposed within a hollow interior of the housing, a battery insert disposed at a front of the housing, and a removable cover plate coupled to the battery insert;
• a contact pin comprising a vertically-oriented cylindrical rod slidably coupled to the housing and extending upward through an aperture in the top wall of the housing, the contact pin comprising a groove that transversely encircles the contact pin;
• a retaining clip coupled to the groove;
• a main spring positioned within the circuit cavity of the housing between the retaining clip and a spring plate disposed below the contact pin, the main spring configured to bias the contact pin upward such that the retaining clip presses against an upper surface of the circuit cavity;
• a contact spring mounted within the circuit cavity, the contact spring comprising a contact spring mount, a positive battery terminal tang extending forward through the battery insert, a contact armature extending obliquely upward toward the contact pin, and an adjustment armature extending adjacent to the left side wall of the housing;
• a calibration screw threadedly coupled to an adjustment aperture in the left side wall of the housing, the calibration screw configured to push against the adjustment armature to raise or lower a point of contact between the contact pin and the contact armature;
• an LED lamp mounted to the rear wall of the housing and having an anode and a cathode;
• a negative terminal positioned within the housing adjacent to the right side wall, the negative terminal comprising an LED negative armature electrically coupled to the cathode of the LED lamp and a negative battery terminal tang extending forward through the battery insert;
• and,
• a battery positioned within a battery cavity of the battery insert, the battery comprising a positive case in contact with the positive battery terminal tang and a negative case in contact with the negative battery terminal tang, the battery being removable by detaching the cover plate;
• and,
• wherein depression of the contact pin against the bias of the main spring causes the contact pin to contact the contact armature to complete an electrical path extending from the positive case of the battery, through the positive battery terminal tang, through the contact spring, through the contact pin, through the retaining clip, through the main spring, through the spring plate, through the LED positive armature to the anode of the LED lamp, through the LED lamp, through the LED negative armature, and through the negative battery terminal tang to the negative case of the battery, thereby illuminating the LED lamp;
• and,
• wherein illumination of the LED lamp indicates that a distance between the bottom wall of the housing and an upper surface of the contact pin corresponds to a predetermined distance.
