4th Axis Rotary Module Upgrade - 4040/3030 CNCs, single kit
✔️ Drop-in upgrade for 4040/3030 CNCs with 10:1 gear ratio

The 4th axis rotary module adds rotary motion to CNC setups, expanding carving capabilities beyond standard 3-axis work. It’s designed as a drop-in upgrade for 4040-PRO, 4040-PRO MAX, 3030-PROVer Ultra, and 3030-PROVer MAX machines, enabling angled and rotary carving. For the 4040 series, an offline controller (B0C582HQ6Z) is required to drive the 4th axis; the 3030 series includes the offline controller.
