Setting Up the Revolution Rotary Axis with Redline Control: A Complete Guide
If you’ve been looking to expand your CNC capabilities into true 4-axis machining, the Revolution Rotary Axis paired with the Redline CNC control system delivers a powerful, plug-and-play solution for your **Onefinity CNC machine.
In this guide, we’ll walk through the full setup process—from unboxing to your first carve—so you can get up and running quickly and confidently.
Optional Riser Blocks: Unlock Larger Projects
Right out of the box, your rotary is ready to go—but if you plan to machine larger diameter stock, installing the optional riser blocks is a smart first step.
The process is straightforward:
Remove the tailstock and chuck head from the gantry
Insert the keyed riser blocks (they align easily top and bottom)
Secure everything using the included hardware
This added height gives you more flexibility for larger projects without compromising stability.
QCW Mounting System (Recommended Setup)
If you’re using a QCW (Quick Change Wasteboard), mounting your rotary is fast and repeatable with the included hardware kit.
The system uses:
Mounting brackets
Spacers (specific to each side)
Locating shafts for precise alignment
Once installed:
The locating shafts slide into QCW-mounted brackets
Everything locks in place with hand screws
You get consistent positioning every time
This is the cleanest and most repeatable setup for production workflows.
No QCW? No Problem.
If you don’t have the QCW system, you can still achieve excellent alignment with a simple trick:
Use a V-bit to carve a straight reference line across your wasteboard
Align your rotary axis to that line
Mark and drill mounting holes
Install threaded inserts for a secure, repeatable mount
This method ensures your rotary is square to your machine—critical for accurate carving.
Plug-and-Play Wiring (Seriously, It’s That Easy)
One of the standout features of the Revolution rotary is how simple it is to connect:
Plug the 8-pin cable into the A-axis port
Connect the 3-pin homing sensor cable
Power on your system
That’s it—no complicated wiring, no guesswork.
Redline Controller Setup
Inside the Redline interface, setup is quick:
Navigate to Program → Config
Load the Revolution Elite defaults
Confirm the A-axis is enabled and reversed (as expected)
Once loaded, you’re ready to:
Jog the rotary axis
Home it using the built-in inductive sensor
Begin testing motion immediately
Loading Material & Adjusting the Tailstock
With your rotary active, it’s time to load your workpiece:
Secure material in the chuck using the included key
Adjust the tailstock along the rails
Tighten the support against your material
Lock everything firmly in place
The system includes both inward and outward jaws, giving you flexibility depending on your material size and shape.
Probing the Rotary Axis
Just like standard CNC workflows, probing ensures accuracy:
Position your bit over the probe center
Connect the probe magnet to your collet nut
Select Rotary Probing in the interface
Input your bit diameter
The system will automatically:
Probe Z (top surface)
Probe X (side)
Probe Y (rear)
Once complete, your work coordinates are set and ready.
Ready to Carve
After probing:
Raise your Z-axis to clear the chuck
Move to your XY start position
Load your file
You’re now ready to start carving in full 4-axis mode.
Why This Setup Matters
The combination of the Revolution Rotary Axis and Redline control system brings true industrial-style rotary machining into the hobby and prosumer space—without the complexity.
You get:
Fast setup
Reliable alignment
Plug-and-play integration
Seamless software control
And most importantly—you unlock entirely new types of projects.
Final Thoughts
Whether you’re carving table legs, custom columns, or intricate wrapped designs, adding a rotary axis transforms what your CNC can do.
And with this setup process, you’ll spend less time configuring—and more time creating.
