Do you have a shot of the toolpath?
Was the gcode done with grasshopper or did you generate the 3D model using grasshopper and then used a different software to generate the gcode?
no i generated the model in gh then i used rhinocam for the gcode
What finishing process do you use?
I presume you are using a very sharp ball nose cutter and then having to somehow sand this and then apply varnish or oil?
Are the white cells cut right through the plywood?
I don’t normally like CNC machined plywood but this is a very good example!
i used 8mm ball end for the finishing , but the stepover was like 10% of the diameter which took some time , for the sanding i used sanding brush and yes then i applied varnish to it , yes the white cells are cut.
Did you use the sanding brush on the CNC or a handheld tool??
no i used this that can be attached to a drill .
I will have to try these! I always just assumed they were very coarse wire brushes for stripping paint. Now I have searched for sanding brushes I can see there is a whole range of them!
yes actually they work perfectly for sanding 3d surfaces and details 
Really cool use of plywood.
I am Learning Plywood relief milling arts, If you dont mind can you share the STL or Script Screenshot?
