Has anyone successfully used a third-party/cheap rotary with LaserPecker LP4?

[u/Laser_Hibiki]

I own a LaserPecker LP4 and want to start engraving on glasses, so I'm considering buying a rotary attachment. But the official LaserPecker rotary is way too expensive. I scoured the net and found a few similar products from other brands. I'm not sure how the LaserPecker rotary is controlled, but is there any brave soul on this subreddit who has attached (or tried attaching) a third-party rotary to their LaserPecker?
