Feature:
Automated Pressure Advanced Calibration
Nozzle Probe
 
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.
