Overview of the Video

In this video, the creator demonstrates the rotary fourth-axis functionality of the Makera Z1 CNC machine. The video documents the full testing process, including the introduction of the fourth-axis components, installation and setup, and two machining tests: rotary 3D carving and indexed milling.

The focus of the video is on showing how the Makera Z1 performs with a rotary axis installed, using real machining operations and visible results.

Fourth-Axis Components Shown in the Video

At the beginning of the video, the creator introduces the main components used for the fourth-axis setup, including:

• A reversible four-jaw chuck
• A stepper motor
• A tailstock with a live center

These components are shown as part of the rotary fourth-axis assembly used during the tests.

Installation and Setup Process

The video then walks through the installation and setup of the fourth axis on the Makera Z1. This includes:

• Mounting the rotary axis onto the machine
• Connecting the necessary components
• Performing initial setup steps before machining

The creator explains and demonstrates these steps to prepare the machine for testing.

Rotary 3D Carving Test

The first machining test shown in the video is rotary 3D carving.

• An epoxy block is used as the workpiece
• Different cutting tools are used for roughing and finishing
• Toolpaths are prepared and sent to the machine using G-code
• X and Y offsets are set before starting the job

The video shows the full machining process and the final carved result, demonstrating the level of detail achieved on the cylindrical workpiece.

Indexed Milling Test

The second test focuses on indexed milling using the rotary fourth axis.

• The workpiece is rotated to different fixed angles
• Multiple tool changes and machining passes are performed
• Different toolpaths are used to remove material and finish the part

As shown in the video, the final result is a Gridfinity endmill holder, designed to hold four plastic endmill boxes and fit into a Gridfinity system.

Results and Observations

Throughout the video, the creator highlights the machining process and shows the completed parts from both tests. The final results of the rotary carving and indexed milling are presented on camera.

At the end of the video, the creator expresses satisfaction with the overall performance of the Makera Z1 during the fourth-axis testing.

Conclusion

This TechyDIY video provides a documented demonstration of rotary 3D carving and indexed milling on the Makera Z1 CNC machine using a rotary fourth axis. By showing the setup, machining process, and finished parts, the video offers a clear record of how the machine performs in these two fourth-axis applications.
