Bibo 2 dual

The Bibo 2 dual is an FDM 3D printer from BIBO with a 214 x 186 x 160 mm build volume.

Specifications

The BIBO 2 Dual (often referred to in the maker community as the BIBO 2 Touch Laser due to its responsive touchscreen interface and dual capability) is a classic multi-functional Cartesian FDM 3D printer that gained widespread popularity among hobbyists, makerspaces, and schools due to its factory-equipped dual direct-drive extruder setup and an optional modular laser engraving attachment. The machine features a highly robust, fully enclosed frame constructed from 6 mm thick aluminum composite panels (Dibond-style) and clear acrylic viewing windows, ensuring excellent rigidity, high resistance to structural twisting, and optimal heat retention during print cycles.

Calibration

Using the BIBO 2 Dual successfully requires precise alignment of both nozzles to prevent scraping and color cross-contamination. Follow these 8 calibration steps:

• Dual Nozzle Z-Height Physical Alignment

Because both nozzles are fixed to a single carriage, they must sit at the exact same vertical distance from the bed. If one nozzle sits even 0.05 mm lower, it will drag on the printed model when the other extruder is printing, causing print failures.

Common defects

• Hardware defects and mechanical weaknesses
• Toolhead Wiring Harness Fatigue: The cabling package supplying the heaters, thermistors, and fans undergoes constant bending cycles. This leads to copper wire breaks inside the insulation, triggering "Err: MINTEMP" faults.
• Solution: Install a 3D-printed drag chain for the X-axis and replace broken wires with high-flex silicone-insulated cables.

What it is used for

Best applications:

• Dual-Color Printing: Perfect for logos, signs, and decorative boxes printed at moderate speeds.
• Soluble-Support PLA Models: Printing complex geometry with water-soluble PVA supports for clean overhang finishes.
• Light Hobby Laser Engraving: Engraving designs on wood, leather, or paper.
