Rigid3D Zero2

The Rigid3D Zero2 is an FDM 3D printer from Rigid3D with a 200 x 200 x 200 mm build volume.

Specifications

The Rigid3D Zero2 represents the second generation of the Zero platform. It integrates a variety of engineering refinements based on feedback from users of the original model. In this revision, the manufacturer focused on increasing the reliability of the filament feeding mechanism (the extruder) and improving electrical safety and cable routing by shifting to more integrated electronic components.

• Hotend: The printer features a single direct-drive extruder. The hotend assembly is an E3D V6 clone equipped with a 40W, 12V heater cartridge and a built-in PTFE liner. The standard brass nozzle has a diameter of 0.4 mm.

Calibration

To tune your Rigid3D Zero2 for maximum precision and reliability, follow this detailed eight-step calibration procedure:

• Geared Extruder E-Steps Calibration:

Because the Zero2 features a 3:1 gear reduction, its default steps per mm are significantly higher than non-geared direct extruders (typically around 380 - 420 steps/mm). Mark the filament 120 mm from the extruder intake. Heat the nozzle to 200 °C and feed 100 mm of filament via a terminal. Measure the remaining filament.

Common defects

• Hardware defects and mechanical weaknesses
• MKS Gen 1.4 Motherboard Overheating:
• Symptoms: Print freezes mid-run, stepper motors stop responding, or X/Y layer shifting occurs during long jobs.
• Cause: The motherboard and A4988 drivers are located in the enclosed bottom metal compartment of the printer. Under high bed heat (e.g., 100 °C for ABS), the compartment heats up, triggering thermal shutdown in the stepper drivers.

What it is used for

Best use-cases

What it prints well:

• Functional PLA and Tough PLA Parts: The box-style frame and geared extruder produce precise gears, enclosures, and structural mounts.
• Flexible Filament (TPU/TPE) Components: The double-sided clutch mechanism handles flexible filaments well, allowing for reliable printing of gaskets, seals, and flexible hoses.
