Anet A2

The Anet A2 is an FDM 3D printer from Anet with a 210 x 210 x 210 mm build volume.

Calibration

• Verify the printer variant before touching firmware, leveling, or slicer profiles.

Action: Confirm whether your A2 is the 220 mm bed version or an extended 270 mm version, and identify whether it uses the LCD 2004 or 12864 control panel. Also confirm the installed frame color, since some community listings describe multiple A2 variants with different option bundles.

Common defects

• Open-frame sensitivity to warping and drafts: The A2 is described as a solid aluminum-frame, open construction printer, which is helpful for rigidity but not for thermal stability.

Symptoms: Corners lift on ABS/PETG, tall parts lean or split, and first layers behave differently depending on room airflow.

Cause: Open-frame bed-slinger geometry exposes the build chamber to ambient temperature swings; cooling fans and room drafts influence shrinkage.
