BLTouch vs. Other Sensors

■ BLTouch 

BLTouch must be installed perpendicular to the ground.

If BLTouch push-pin can't be perpendicular to the ground, BLTouch will out put wrong signal.


■ Micro switch

BLTouch is equipped with all three function as micro switch, servo motor and also servo arm.

Comparison would be pointless if micro switch sensor for bed leveling does not include the retraction

and deployment method.

■ Inductive Proximity Sensor

At Inductive Proximity Sensors, to calculate the sensing distance for other application conditions the following parameters, which affect the sensing distance, must be taken into account.

(For example : Variations in ambient temperature(Kθ), Different types of object material(Km), Size of the object to be detected(Kd), Variation of supply voltage(Kt))  

Sa(assured sensing distance) = Sn x Kθ x Km x Kd x KtSn : nominal sensing distanceIf non-contacting Inductive Proximity sensor can receive the same Parameter at whole working area, it must be the best auto bed leveling sensor for 3D printers.

But who can provide this?

Most of metal beds have various temperature(Kθ) areas at one bed, and its thickness(Kd) and object material(Km) are also various because of bolts, nuts, or supporters etc.
