So I finally got around to testing one of the reasons I made this CNC today.
Chess board. Since I didnt have a piece big enough for this large board I decided to just use MDF.
- All the internal squares were done with a V groove router bit set to 1.5mm
- I then went around the outside edge with the V groove set to 3mm
- Then I went around the edge using a 1/8" cutting bit, down to 13mm (depth of wood) 1mm at a time, w/ 3 holding tabs of 1mm in height x 10mm long per side.
The result, was perfect (except that without end stops one screw up and you will NEVER get back to where you started). I am off center on my outside perimeter, but its just a test.
The pieces are all printed (long ago) on a muve3d dlp SLA based printer (stunning quality) and my end goal for the board is putting an Iowa Hawkeye logo in the middle (engraved), but im not sure how to pull that off.
So now i need to find a supplier of high quality wood that is big enough. No where around here sells any good wood, in size.
btw, here are some pics
I know the parts look shiny and maybe after sprayed, but they are 100% fresh off the printer, no touch up, or sanding.
