4th Axis Module, Makera Carvera

If you push a Carvera beyond 3 axes, the Makera Carvera 4th axis module transforms a desktop CNC into a machine capable of handling rotary contours and multidirectional machining without repeated setups.

This module is specifically designed for the Carvera series and uses a Harmonic Drive reducer: a nearly backlash-free drive technology that minimizes positioning errors and play during rotation. It’s crucial for achieving repeatability and finesse on technical or artistic parts.

Components & Performance

• Drive system: Harmonic Drive for smooth, precise motion with minimal backlash.
• Motor: Compact NEMA17 stepper, efficient at maintaining consistent torque.
• Rotation precision: ~0.01° for extremely fine details.
• Max speed: up to 2400°/min for smooth cycles on complex shapes.
• Work area: Ø 92 mm × 240 mm, suitable for cylindrical or long parts.
• Materials: wood, plastics, non-ferrous metals for projects from craft to functional parts.

Why This Module Makes a Difference

On a standard 3-axis CNC, you often need to reposition the part to machine multiple faces or round shapes: time-consuming and error-prone. The 4th axis allows:

• Sequential machining without repositioning
• Switch from flat to cylindrical surfaces without re-fixturing
• Optimized operations via precise control of axis A

MakeraCAM or alternatives like Fusion 360 and VCarve handle this additional axis and generate the correct G-code.

Usage Tips

• Installation: follow the provided procedure for proper mechanical and electrical integration.
• Calibration: carefully calibrate axis A (starting position, zero return) for precision and repeatability.
• 4-axis machining: favor indexed machining for technical parts before moving to simultaneous motions.
• CAM: use adapted strategies – slow rotation for finishing, roughing with clear clearances – to fully exploit the Harmonic Drive.

If you want to push your Carvera to the limit, this 4th axis module is not a gadget: it’s a bridge to freer shapes, complex prototypes, and cleaner finishes without multiplying setups.
