Types of Auto Leveling Methods
There are several methods used in 3D printers for auto leveling, each with its own advantages and limitations. The two most common methods are:
1. Inductive/Capacitive Sensor Auto Leveling
Inductive or capacitive sensors are often used in auto leveling systems. These sensors detect the distance between the sensor probe and the print bed by measuring changes in the electromagnetic field (inductive) or changes in capacitance (capacitive). They are non-contact sensors and can be mounted near the print nozzle or on the printer frame. Inductive sensors are commonly used for metal print beds, while capacitive sensors are suitable for both metal and non-metal beds.
2. Probe/Tactile Sensor Auto Leveling
Probe or tactile sensors physically touch the print bed to determine its levelness. These sensors typically consist of a spring-loaded mechanism that allows the sensor to apply pressure to the bed. When the sensor touches the bed, it triggers a switch or a change in resistance, indicating the bed’s position. Probe sensors are commonly used with glass or other solid surfaces and can be more accurate than inductive or capacitive sensors.
Each auto leveling method has its own set of advantages and considerations. Inductive or capacitive sensors offer convenience and ease of use, while probe sensors may provide greater accuracy.
