Deltacomb DC-20 Flux

The Deltacomb DC-20 Flux is an FDM 3D printer from Deltacomb with a 190 x 190 x 250 mm build volume.

Calibration

• Unbox, inspect the delta stack, and confirm mechanical freedom before powering on.

Action: Remove the printer from its packaging, then visually inspect the three tower rails, effector arms, belt paths, wiring conduits, and build plate mounting points. Check that nothing rubs, binds, or appears loose, and gently move the effector through its reachable workspace by hand with the machine unpowered to verify smooth, symmetric motion.

Common defects

• Unheated bed limits material range and can reduce adhesion on demanding plastics.

Symptoms: Corners lift, first layers release early, tall parts wobble loose, or PETG/ABS-like materials behave inconsistently on large footprints.

Cause: The FLUX Delta teardown describes a thick, metal, unheated build plate, and the review material emphasizes that the platform was designed around easy PLA-style use rather than broad heated-bed material compatibility.
