The Pyr0-Piezo Z-Axis Sensor =================== +**What's this for?** +-------------------- + +This design incorporates two different enhancements: + +1. An Ultra-Sensitive Z-Axis sensor utilizing the mechanical force of the nozzle touching the bed, giving a direct measurement with no offsets or referential assumptions to consider + +2. (Optional) An FFC Cable chain [(Flat Flexible Cable)](https://en.wikipedia.org/wiki/Flexible_flat_cable) that can carry the entire print-head's signals and current in a clean and organized way + +**Why is this better than X sensor?** + + - Vs. Inductive / capacitative sensors: No Offset, more accurate, doesn't require special surface + + - Vs. Mechanical touch (BL-Touch, servo mounted endstops): No Offset, more accurate + + - Vs. removable pressure sensor: More accurate, no need for attaching a device only for levelling + + - Vs. Optical rangefinder / Time of Flight: Much more accurate, doesnt require specific surface + + - Vs. Mechanical endstops: All the things + + - Vs [PrecisionPiezoUK](https://www.precisionpiezo.co.uk/resources-osh) version: No potentiometer calibration required, better false-signal filtering + Features: + - Self-calibrating (no more fiddling with tiny potentiometers!) - Ultra-precise z-height measurements - Zero offset (The nozzle itself is the sensor!)
