New Bed Level Sensor for 3D printer

High resolution Distance sensor

Similar projects worth following
It detects the distance from the nozzle to bed and then adjust Z axis height in real time.

There is no Z axis move up and down for Probe, so it will be much fast.

This is a high resolution inductive Bed Distance Sensor, it can measure the distance from bed to nozzle with distance resolution

  1. with this sensor the printer can adjust the z axis in real time if the bed plate is not flat in every point,also no need to do probe points before every print.not only the plate not flat itself but also the high and uneven temperature will also cause the plate to expand and contract.

  2. you can do mesh bed leveling like normal proximity sensor but much faster with this sensor, because it's no z axis down and up at every probe point.so you can do more probe points in short time.

 Distance resolution:0.01mm 

 Operating Range:5mm

 Repeatability:+/- 0.005mm

 Communication port: I2C 

 Connection| only 4 wires: GND,5V,I2C_Data,I2C_Clk   

Calibrate: 

Send gcode M102 to Calibrate, we need to calibrate this sensor before first use or the bed plate have been changed to different materials, Because different metal plates are made of different materials, they may have different electromagnetic properties. normally this process will take about within one minute in 3D printer 


Here is the data diagram of this sensor, we can see that the distance resolution can be 0.005 to 0.01mm below the 5mm

What temperature will this sensor survive in?

  Are you sure? yes | no

I am wondering how you connect this sensor to the printer. Does it need a special port ? Is it only for a certain type/brand of printer ?

  Are you sure? yes | no

this sensor use the I2C, so any board have 2 free gpios can connect to it.

  Are you sure? yes | no
