While moving with the extruder, the X-axis motor works as a generator. You will create a small amount of electricity and the LCD might flicker. Move with the extruder reasonably slowly and in the future always use the printer's controls.

⬢Move the extruder manually all the way to the left.

⬢By rotating BOTH threaded rods at the same time on the Z-axis move the nozzle until you reach the heatbed. Try rotating both the rods equally!

Don't place the steel sheet on the heatbed during the entire P.I.N.D.A. probe adjustment process. Wait for the XYZ calibration.

⬢Move the extruder carefully all the way to the right.

⬢If an adjustment is needed, you can lower the nozzle height by rotating the right Z motor counter-clockwise.

⬢Move the extruder to the centre of the X-axis.

⬢Take a zip tie from the package and place it under the P.I.N.D.A. sensor. Use the middle part of the zip tie, not the tip.

⬢Release the screw holding the P.I.N.D.A. sensor and gently press it against the zip tie.

⬢Tighten the screw on the P.I.N.D.A. holder again. Proceed carefully as you might break the holder!

⬢A correct height of the P.I.N.D.A. sensor compared to the nozzle should be similar to the last picture.
