cnc engraving logos with Fusion 360 and epoxy on a Snapmaker machine#snapmakervideocontest
Channel: Malachai80

In this short video I show my process of cnc engraving boards with my Snapmaker Artisan and Fusion 360, filling the engraving with epoxy/resin and making the surface smooth and shiny again in under 2 minutes.
I have cut this video for the #snapmakervideocontest (CNC Challenge) in a very short and intense cut. There is a much longer version on my channel.

the important points for using cnc with a Snapmaker machine and Fusion 360:
1) the diameter of the bit has to be smaller than the smallest path to engrave (sounds logically, but otherwise Fusion will skip this part)
2) use 2d adaptive clearing in Fusion 360 and set minimum cutting radius, radial stock to leave and axial stock to leave to zero, otherwise the very detailled parts will not be cut.
3) I used a 1mm bit (link below) which is not standard in the Snapmaker tool library, that can be imported into Fusion 360. I copied and adapted the 3,125mm one. 
4) the work origin on the Snapmaker Artisan (or 2.0) has to be the same spot as the origin of coordinate system in Fusion (in my case: the center)
5) use run boundary to prevent crashes during work process BUT: raise z above any clamps or the crash will happen during run boundary
6) as my Artisan (could depend on firmware) does travel x/y first before engraving, I set my work origin and afterwards raise my z by 100mm to prevent crashes
7) safety first: Use gloves and a mask while working with resin, use a mask and safety googles while sanding

I built a suction system für the cnc - I am planning to do a video on this in near future. That keeps the interieur of the Artisan clean. And my room, as the vacuum I use (link below) has an exhaust too.

As i engraved cutting boards the epoxy should be foodsave.
I used SKresin 3221 with Epohard 3200 from

I use Einhell machines as they all use the same battery, so its possible to switch between machines without the need of countless differten batteries and charging devices
