This screen capture from the video The Rotary Module - How to Use Rotary Laser Engraving seems to imply that it is possible to mount square materials for Rotary Module CNC.
Is this accessory available? Square material is much more readily available than round material.
My understanding is you take the diagonal of the material to figure out the (virtual) diameter and the tool will cut some air along the way while rotating the square stock. I don’t have the rotary add on yet (own order) but I assume the Snapmaker software is not a full fledged CAD/CAM solution where you could indicate a square stock on all sides to determine its true location on the rotational axis besides the offset for the tool head…
