Discover the Possibilities: The Genmitsu 4th Axis Rotary Module Kit is a drop in upgrade that enables your 4040-PRO CNC machine to carve from different angles and positions or with the right software full 3D rotary carving. Additionally, the G-code for the 4th axis must be sent using an offline controller (ASIN: B0C582HQ6Z), which should be ordered together with the 4th axis to ensure proper functionality. NEMA17 Planetary Geared Stepper Motor: Take advantage of the high torque provided by the NEMA17 motor, which allows the motion system to rotate workpieces with more force and precision than any other belt-driven rotary modules on the market. Versatile dimensions: Adapt to various project requirements with a center height of 50mm, total height of 86mm, and material lengths with tailstock from 10-100mm; without tailstock from 10-200mm for flexibility. Applicable Material diameter: 2-50mm. Precision Control: Utilize the 10:1 reduction ratio for precise control, offering a minimum angle of 0.1° and a maximum angular speed of 300° per second, ensuring high speed and unparalleled accuracy. Software & Controller: To use a 4th axis on your CNC machine, you will need CAD/CAM software that can generate toolpaths for rotary motion. While options like Fusion 360 and Vectric are recommended, it's important to note that most software capable of generating 4th axis toolpaths is not free., Weight: 6.4595442766 pounds, Manufacturer: SainSmart
