Anycubic Chiron

The Anycubic Chiron is an FDM 3D printer from Anycubic with a 400 x 400 x 450 mm build volume.

Calibration

• Establish the machine’s baseline before tuning anything else.

Action: Power on the printer, confirm the build plate is clean, and inspect the mechanical stack: belt tension, wheel preload, Z-screw alignment, and the bed’s free movement over the full 400 mm travel. Verify the nozzle is the stock 0.4 mm size and that the slicer profile matches 1.75 mm filament and a Cartesian FDM machine.

Common defects

• Large-bed first-layer inconsistency: The most recurring issue reported across reviews and user feedback is uneven adhesion or leveling behavior on the very large 400 × 400 mm bed.

Symptoms: One side of the bed may print too close while another side looks under-squished; long edges can detach during a print; first-layer lines appear inconsistent across the surface.
