I have a 12-watt Swift and an R1 rotary
The problem is, I can’t plug them together.
Does it matter if the rotary is an R1 or an R1-B? I’ve seen it mentioned both ways online.
Is there some kind of adapter cable or a DIY solution to get the rotary up and running?
The cable to the Yaxis motor is unplugged and plugged into the rotary motor. If it does not fit, tell us what you have for the connectors (pin count). If the rotary is an Atomstack unit, it should fit.
The Swift 12W is a pretty new device:

It has USB connector for accessory.
You can confirm it in the user manual also:
(It is a pretty big file)
The R1 roller has black plug wire and white plug wire:

Need some cable which converts the black plug wire / white plug wire to usb to connect it to the Swift.
Can you post an image of both ends of the white plug wire? Also include an image of the rotary power connector. The manuals have poor images.
The black plug wire is just a cross-over cable, sometimes needed for other laser or rotary models.
I have no idea why they listed that USB port for a rotary. A USB cable is normally not rated for the amount of current the stepper motor in the rotary would require.
Given how some of these things work, this would be a problem because … ?
I seem to have used up all my [sarcasm] tags. 
I am pretty sure those micro fine wires used in the cheap USB cables would be stressed to pass even 2 amps. EDIT: It finally dawned on me a reply was not needed…
Have you checked Amazon? 
I’ll be near the product later, but I found a YouTube video where they show it: https://www.youtube.com/watch?v=GYs_GYCX6ow. It shows the cables at the 1-minute mark.
That white cable is an extender cable. It has a plug (which goes to the rotary motor) and a socket (where you plug in the cable that goes to the Yaxis motor). You unplug the Yaxis cable from the Yaxis motor and plug it into the socket end of the white extender cable.
Once you get it hooked up, do the Lightburn Rotary Setup as described in the rotary manual.
Here’s how to use a R1 rotary. Download the document below and change the extension from .txt to .docx. It is a word document

My Y axis servo is on the front of the machine under the carriage but yours may be in a different place. As mentioned above you don’t connect the R1 Rotary to a USB port but to the Y axis servo motor.
Finally made it to my rig and shot some quick videos of the equipment:
Nice. Have you hooked it up yet?
Thank you very much for your help, based on the instructions we were able to connect the machine to the accessory.
Our next problem is that, for example, the circular pattern is engraved as an oval, not as a circle (I’m attaching a video):
You either have your steps per rotation or your Object. Diameter / Curcumference set wrong. Or possibly both are wrong. Start with steps per rotation. When this setting is correct, the chuck will make one complete rotation and return to start when the test button is pressed. If it does not, you must make the changes to steps until it make exactly one complete rotation. Once that is set correctly, it will never need to be changed. Then, and only then can you set your object diameter / circumference to the diameter / circumference of your workpiece.
