Touchoff Sensor Assembly

The touchoff sensor is the primary feedback mechanism for Z-axis depth registration. If the sensor fails to trigger or triggers prematurely due to wood dust ingress or mechanical fatigue, the software cannot reconcile the bit position with the encoder data, resulting in a calibration failure.

Z-Axis Lead Screw and Nut Kit

Mechanical binding in the Z-axis lead screw prevents the spindle from moving smoothly during the calibration sequence. If the motor encounters excessive resistance (torque spikes) before the touchoff sensor is triggered, the system aborts the calibration routine to prevent hardware damage.

1/4" Precision Collet

Improper bit retention due to a worn or debris-clogged collet causes the bit to shift during the downward touchoff force. This displacement creates a variance in the expected vs. actual Z-travel, leading to an 'out-of-bounds' calibration error in the control software.
