Anet ET4

The Anet ET4 is an FDM 3D printer from Anet with a 220 x 220 x 250 mm build volume.

Calibration

• Start with a true mechanical baseline before touching any slicer profile.

Action: Power the printer on, home all axes, and inspect the frame for square geometry, loose belts, and wheel/bearing play. Confirm that the gantry moves smoothly across the X and Y travel without binding, and that the single Z-axis lead screw advances evenly from bottom to top. Tighten obvious hardware only until it is secure; do not over-torque the frame or bed carriage.

Common defects

The ET4 is best understood as a capable budget machine with strong feature density, but also with some recurring weaknesses that appear in reviews and owner discussions. Several issues are not catastrophic defects, yet they are important because they affect reliability, confidence, and long-term maintenance.

1. Firmware is functional but basic.
