Onefinity CNC Easy ATC by RapidChange ATC

Onefinity is excited to announce the Easy ATC (Automatic Tool Changer).

This advanced accessory is ideal for users who are very familiar with operating a CNC machine. It introduces an additional layer of complexity, particularly at the beginning of ones CNC journey, and should only be considered once a user has gained sufficient familiarity with CNC operations without it.

The worlds first collet spindle ATC (automatic tool changer)

Onefinity is excited to partner with RapidChange ATC to help bring to market the Onefinity Easy ATC.

The Onefinity Easy ATC is a new, revolutionary, automatic tool changer that’s designed to work with Onefinity Spindle Kit by Redline CNC spindles (or similar), making automatic tool changes without the hassle, complexity and high cost that’s associated with traditional ATC Systems.

The Onefinity Easy ATC is the most affordable and easiest way to add a reliable automatic tool changer to your Onefinity CNC. The Easy ATC features a sleek and stylish patent pending design, easy to load tool pockets, load and unload sensors and is designed to be used with the Suckit SM Dust Shoe (coming soon) to ensure your shop stays clean.

The Onefinity Easy ATC is the only Automatic Tool Changer on the market that allows you to use your existing collet spindle to easily change tools automatically. In addition, the Easy ATC features load and unload sensors to help ensure your tool gets loaded properly. If a tool gets loaded incorrectly, the sensors will trigger an alarm and stop the CNC until the issue is corrected.

What you get:

Easy ATC with 4 Tool Pockets

Patent Pending design

Four (4) high quality, balanced Spindle collet nuts

Load/Unload Sensors on each Tool pocket

Fully Supported by RapidChangeATC and Onefinity

All required wires and cables

Mount Anywhere Table Mounting Bracket

Easy ATC QCW Mount for quick, easy, reliable installation (Optional)

Works with all Onefinity machines

And much more…

Simple, Safe, Easy to Setup, Affordable

The Easy ATC is incredibly easy to set up, using just a single cable that’s plug and play with the Onefinity CNC machines (Elite machines require some internal wiring). There’s no need to run a multiple of cables and airlines.

Perhaps the most exciting thing about the EASY ATC is that it costs a fraction of what a traditional ATC costs.

When you combine Onefinity CNC machines with the EASY ATC you truly have a CNC that’s ready to take your business or side hustle to the next level.

What Spindles are compatable?

First and foremost, you’ll need a spindle, as the Makita router is not compatible with the ATC. You’ll also need an 80mm spindle that can operate in reverse.

We highly recommend the official Onefinity CNC Spindle Kit by Redline CNC. It’s the only spindle we can guarantee will work seamlessly right out of the box. Plus, it’s backed by Onefinity’s warranty and support, ensuring you have a reliable and supported solution.

Suckit SM (Optional)

One challenge that most ATCs face is dealing with dust collection. We know that dust collection is a big deal, that’s why our engineering team has been working closely with the RapidChange ATC team to help develop a variation of their existing product that will work with a dust shoe. Out of this came the EASY ATC. The EASY ATC Works with our new spindle mount dust shoe, the Suckit SM (Spindle Mount). The Suckit SM is coming soon and will be available to purchase separately before your Easy ATC ships.

Please note: The original Suckit Dust Boot does not work with the Easy ATC.

Mount Anywhere

The Easy ATC is designed to be setup anywhere the Spindle can reach. Want it at the back and out of the way? Need it located on the right side to allow long material? Or maybe you want a quick, simple, and clean set up that the QCW Easy ATC Mount offers.

In addition, the EASY ATC is designed to allow for multiple units to be tethered together. You can start with a 4 pocket and add more as you grow!

Pro Series Easy Adapter (required for BB controller)

To make the Easy ATC plug and play compatible with our Pro Series machines the Pro Series Adapter is required. The Pro Series Easy Adapter is extremely easy to install. Simply plug the supplied cable directly into the DB25 connector that’s located on the back of the Pro Series Controller (Buildbotics). Once connected, you’ll have the ability to quickly and easily connect the Easy ATC. (Only for BB Buildbotics controllers. Not for Elite Masso machines).

In addition you will be able to easily add Infrared homing sensors, our EaZy-Z Tool setter, spindle and potential future accessories.

Simple Tool Insertion

Because the tools simply slide into each independent collet and placed in the tool pockets, there is no need to have holding fixtures and fumble with wrenches to set each tool. In addition, gone are the days of removing a tool from your spindle, only to have it slip out and get damaged.

It’s all about efficiency

With the Easy ATC, you no longer need to limit your machining strategies to the fewest tools possible. Say goodbye to creating long tool paths just to avoid bit changes. The Easy ATC eliminates the need to plan your day around tool changes.

Stop watching your machine sit idle while you search for wrenches and change tools manually and get down to business.

Safe and reliable. And we have the data

When we first encountered the RapidChange ATC, we knew it was a fantastic idea. So, we decided to put it to the test. After countless hours of testing its repeatability, holding torque, usability, and performance, the RapidChange ATC exceeded our expectations.

Please note:
The only spindle we can guarantee and have been tested is the Onefinity Spindle Kit by Redline CNC. It’s also the only one that we can provide technical support with if you have any issues with the ATC. While any 80mm er20 collet spindle that can go cw and ccw may work, we will not be able to give technical support if you need it with the spindle/ATC.

If you value technical support, we recommend the Onefinity Spindle.

We hope that helps!

Isn’t this not very useful for BB till the tool setter for original/PRO comes out? I mean yeah you can change the tool but you would still need to stop and probe Z right?

It wouldnt be my first choice but i assume you could use collars to set bit height in a collet… but a bitsetter would by far be preferable and safer.

:exploding_head:

Never expected something this easy/cheap. I don’t really need it, but damn, would be nice to have.

As someone who absolutely loves their BB controller and has absolutely no desire to upgrade, thank you for including the ‘legacy’ hardware this year. Though legacy is clearly the wrong word with it being so well supported still.

We’re glad we can make it happen!

I am impressed by the price.

Is there a max number of tools?

They are sold in banks of 4, and can be ‘linked’ together…so the limit is…‘infinite’

RIP my wallet between the new spindle, ATC and rotary. :rofl: Thanks so much for listening to the community. I’ve DIY’d some of these things myself (like a cheap spindle and small DIY rotary) since I first bought my machine, but the tight integration between these new offerings and the machine make it worth the investment to me.

All we do is listen :stuck_out_tongue: The community feedback makes the Onefinity better!

For those of us who already have the PWN CNC 80mm 220v, water cooled spindle kit, will this ATC work with them?

We can’t speak to any other spindle than our Onefinity Spindle Kit which it was designed and tested with, but most any er20 spindle should work, if it can rotate ccw and cw, however since this is so spindle specific, we can’t recommend a spindle other than ours.

My understanding is that they are working on the ability for the Tool setting to work on the BB Pro Series. I don’t recall the name of the device but they released it yesterday and it will allow the BB PS to be able to add many of the features that are currently only available on the Elite. The tool setter is one of them along with better homing.

The Pro Series box was made to allow for this ATC. It will expand the BB controllers to allow homing sensors and the tool setter. More info in the months to come!

I have the original Journeyman ordered November 2022. Is that considered pro series?

for this yes, The controller is really what matters, and you have a BB Buildbotics , so choose that one during checkout.
