Rotary attachment laser engraver

Hi folks! How are you? I’d like to know if there is any tutorial about how to set and use that rotary attachment for laser engraving that you can find at thingiverse. Thanks!

Could you please send the link to the thing?

Sorry, I found it. It’s a good idea but needs much adjustments to get the right space between the rollers for the dimension of the cylinder you are engraving

Hope this could help you.

Yes, it helped me a lot. There is a simple explanation from the designer in the comments of the video.
