bdpressureE automatic Pressure Advance calibration sensor

This is an automatic Pressure Advance calibration sensor.   It is specially designed for a printer using a standard mounting pattern (Dragon, Rapido, V6 etc.)    Feature: Automated Pressure Advanced Calibration Nozzle Probe Small and strong: only 6 mm in height, 2mm thick steel Integrated MCU and High speed ADC, No external PCB board required. Small and super soft cable Connects directly to your toolhead board or Pi via I2C or USB.   How does it work? 1. PA Mode:     Automated Pressure Advanced Calibration.     Without printing calibration lines, it just simulate extrusion pressure behavior during acceleration and deceleration while only the extruder is working.     This work process is similar to the Bambu Lab A1 printer, instead, we use  strain gauge, not eddy sensor. 2.  Probe Mode:       Use the strain gauge to sense the nozzle pressure while probing .      It works as a normal switch endstop sensor, so we can just power it and connect the  Z- pin to the mainboard.    Package list: 1 * bd pressureE sensor 1 * USB cable 1 *  Hotend (Option)   WiKi: Probe mode | Wiki GitHub: markniu/bd_pressure Discord:  3D Printscape Video:  youtube
