X-Plus 3

The X-Plus 3 is an FDM 3D printer from QIDI Tech with a 280 x 280 x 270 mm build volume.

Specifications

Here are the verified technical specifications for the QIDI Tech X-Plus 3, based on the provided sources:

• Build Volume: 280 × 280 × 270 mm (Width × Depth × Height) .
• Kinematics: CoreXY structure, which reduces motion inertia and improves printing speeds [3, 5-7].
• Hotend: Maximum temperature of 350°C . It features a high-flow direct drive extruder capable of 35mm³/s [3, 4, 8, 9]. It comes with two sets of hotends out of the box: a copper alloy nozzle for standard filaments and a hardened steel nozzle for abrasive materials [7, 10, 11].
• Nozzles: The standard nozzle size is 0.4 mm, with 0.2 mm, 0.6 mm, and 0.8 mm sizes optionally available.

Calibration

Step 1: Bed Leveling & First-Layer Calibration

• Expected outcome: A perfectly squished first layer that adheres well to the bed without gaps between lines or rough, scraping ridges.
• Tip: Begin by loosening the metal locking nuts located at the bottom of the hotbed before adjusting the three red nylon nuts . Use the provided leveling card or a piece of A4 paper, adjusting the knobs until you feel slight friction when moving the paper under the nozzle [1, 2].
