II – Calibrate the Inductive Sensor

Step 1

Move the nozzle back to left behind corner of the print bed and power on the printer. The sensor indicator becomes red and the sensor starts to sense the print bed.

 

Tips:

In order to get consistent behavior from the sensor, we need to make sure it gets the best distance from the print bed. It’s recommended on the user guide that this distance can be among 2-3mm. But Mr. Irvin Shapiro suggests us to keep it at 2mm to avoid the slight variability every time when we run the leveling procedures. A folded post-it note plus a ruler will make 2mm thickness.

 

 

Step 2

Place both the ruler and the post-it note together in beneath the inductive sensor.

 

Step 3

Slide the ruler with the post-it note together between the sensor and the print bed. If the movement is smooth and a soft friction can be felt, it means the spacing between the sensor and the print bed is just what we want.

If not, press the screw on the side of the hot end (as above picture shows) inward and now we can adjust the height of the sensor. If the sliding is too tight, pull the sensor a little higher; if it’s loose, push the sensor a little lower.

 

Step 4

Move the hot end to the center and turn the sensor screw anti-clockwise with a screwdriver until the sensor indicator’s off.

 

Step 5

Then clockwise turn the sensor screw back until the indicator turns red again.

 

Step 6

Repeat above steps to make the indicator to go off and on, off and on again.

 

Now we have the right distance between the sensor and the print bed and the inductive sensor is well calibrated for a proper sensing.

 

We can proceed to manual bed leveling procedures.
