Mini Epoxy Granite CNC – 1/4

1. Aweso´e video, well build..
   Dreaming of making myselfs one .
   Btw got me subed !
   Grtz from the netherlands Johny geerts

2. Are you using MDF boards as the datum reference when mounting the hiwin rails? If so what is the flatness accuracy of the end result after molding for the datums of x,y and z axis? Do you think it will be better to attach pre-cut steel rectangular datum bars to the mold? It will be a little more expensive but you will have an accurate datum plane that is flat down to 5-25 microns depending on the quality of the steel rectangular datum bars. The steel rectangular datum bars will provide flatness and parallelism accurate edges.

3. USELESS – impossible to see anything useful at hyperspeed, and no useful detail or design specs. Just another internet jerk-off.

4. where did you source your granite aggregate, sand, and epoxy? i am having a difficult time finding it.

5. Well how long until it's finished and do we get to see it?

6. Awesome CNC project! I'm thinking about making one too. What did you use to seal the inner molds? I assume it was used to make it easy to release. 🙂

7. If you use form ply it will release easily and be reusable plus it is much stronger and resistant to flex when the cavity is filled.

8. Looks nice!

   One suggestion, maybe you could make the table a little bit longer in x direction and close off the gap underneath such that dirt can not fall to the y-rails.

9. So cute little cnc 🙂
