The inclusion of two 16MP cameras will enable you to craft with greater accuracy. The live preview that shows up on your laptop will offer an auto-focus for ease of use and you can drag and drop illustrations and designs into the workspace and it will automatically update and focus (a similar system is in place on the current xTool M1).
The dual-camera system means one will offer a view of the whole project in the design space, while the second camera can track the position of the laser's head and take photos for more precise engraving.
