Anycubic Kossel

The Anycubic Kossel is an FDM 3D printer from Anycubic with a 180 x 180 x 300 mm build volume.

Calibration

• Start with a delta-specific mechanical inspection before powering anything on.

Action: Check that all three towers are rigid, vertical, and equally tensioned; confirm the effector arms snap cleanly into their joints; inspect belt routing, pulley/rail alignment, and the hotend carriage for play. On Kossel Plus-style units, verify the linear rails are smooth across the full travel; on pulley-era units, verify belts are evenly tensioned and not rubbing.

Common defects

1. Time-consuming leveling and calibration on early/non-adjustable builds

Symptoms: First layers vary across the bed, the nozzle is too close in one region and too far in another, and users report that setup before the first print is tedious.

Causes: Delta geometry is sensitive to tower symmetry, effector offsets, and bed tramming; some early Kossel versions also lacked a heated bed and were described as not adjustable, which made manual leveling slow and frustrating.
