Some embodiments of the disclosure provide a flatness detection device. In an embodiment, the flatness detection device includes a back plate, an electromagnet, a cross beam, a probe, and a limiting frame. The limiting frame and the electromagnet are provided side by side on the back plate. The cross beam is located above the limiting frame and the electromagnet. The probe vertically penetrates the cross beam and the limiting frame. A spring is provided between the cross beam and the electromagnet. The spring is movable in a vertical direction by a guide, the movement being at least one of compression and extension.

A method for adjusting height of a 3d printer nozzle. In an embodiment, the method uses a fully wavy line as a reference line. The method includes the following steps. Determining an initial value of a height difference between the nozzle and a bottom of a probe by using a feeler gauge. Moving the nozzle vertically to adjust the height based on the initial value, obtaining a printing height of a first line, and printing the first line. Determining whether the first line is a fully wavy line. Adjusting the height of the nozzle for N times according to a preset step value, and printing N lines with corresponding heights. Determining whether the N lines have a fully wavy line. Calculating the height difference between the nozzle and the bottom of the probe by an equation. Adjusting the height of the nozzle.
