After many trials I think I have nailed it, some what.

After many trials I think I have nailed it, some what. Thanks to all who tiped. Sine wave pattern

Looks great. How’d you do it?

That is Awesome! Thanks for the share I know what I’m doing tomorrow!!

That’s a bigger sine wave “circumference part” than the diameter!

How did you CNC white on black? It seems to me that was painted or something.

@Andrew_Hodel ​ it’s a melamine/chip board. Allready come with a thin layer of paperish.

@Ariel_Yahni_UniKpty oh, so you burn it from brown to black and it’s a CNC laser?

Sorry, most people relate CNC to fast spinning drill bit so that’s what I was thinking. I figured you had painted the top black then CNC’d (or milled) the surface down the color of the wood.

It looks good, it must have taken you a long time to actually implement.

@Andrew_Hodel ​ yes it’s milled. Painting the surface will give you same result. Next stop will be dfx with much smaller gap and laser it.

Well the app is note mine but actually setting the V bit at the correct hight took some tries

Wish there was something cross platform with a better gui

Bro why would a DXF be different than another format?

Also, if you painted it, wouldn’t it be a lot of un-needed work to cover the underlying cuts with tape or something before you painted it against just painting a new one and milling that?

Also, what kind of wood is black on the surface?

@Andrew_Hodel the up linked before generates the gcode for milling. It also lets you export the dxf. So export with very small min and max paths ( laser post ).

I did not paint this and yes you will need to paint it before not after, but if you use ply then paint, let it dry and then carve.

@Ariel_Yahni_UniKpty what is a up which is linked?

@Andrew_Hodel ​ meant to say the link http://jasondorie.com/page_cnc.html
