Pyr0-Piezo Z-Axis Sensor Mount for Creality Print Heads This mount makes the most of the original hardware from the OEM print head, requiring only a few extra screws. Additional parts needed: 2x M3 x 4mm 2x M3 x 12mm The Nozzle Mount needs to be printed with a flexible material like PETG, while all other components can be printed with any rigid filament, PLS/ABS/etc. The original M3 x 6mm pan head screws for holding the fan cover on to the print head are repurposed to hold the nozzle flex-mount.

An Ultra-Sensitive Z-Axis sensor that utilizes the mechanical force of the nozzle touching the bed, providing a direct measurement with no offsets or assumptions. 2. (Optional) An FFC Cable chain 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 leveling Vs. Optical rangefinder / Time of Flight: Much more accurate, doesn't require specific surface Vs. Mechanical endstops: All the things Vs PrecisionPiezoUK 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!) Compatible with ALL surface types No plugging in removable sensors for leveling FFC Cable chain for a clean connection between print head and controller Onboard switchable DC buck converter for 12v or 5v fan operation LED Feedback on all PWM components Standalone version available for drop-in installation Credit must be given to precisionpiezo.co.uk for getting me started on this project and giving me a place to start. I built a version of the FFC cable chain based on their electrical designs, but found the calibration of the circuit to be very fiddly. I've since started from scratch using my own BOM and designs, while including an onboard microcontroller to handle auto-calibration. Given that every 3D printer is different, I wanted this sensor to be as easy and stable as other sensors available on the market, but with the increased performance of a piezo sensor.
