Flsun Super Racer

The Flsun Super Racer is an FDM 3D printer from Flsun with a 260 x 260 x 330 mm build volume.

Calibration

Below is a practical calibration workflow tailored to the Flsun Super Racer’s delta kinematics, high-flow Volcano hotend, and speed-first design philosophy. The key principle is that a delta printer can be mechanically “healthy” yet still print poorly if its geometry, effector alignment, rod consistency, tower tramming, probe behavior, and slicer acceleration are not tuned together.

Common defects

The Flsun Super Racer has a strong reputation as a fast delta printer, but the supplied sources also reveal a set of recurring limitations that show up in real use. These are not all “defects” in the sense of broken hardware; several are more accurately design tradeoffs or firmware-and-motion side effects that become visible when users push the machine toward its advertised speed envelope.
