Thank you for the reply... I intend to make painting the shade of lamps.. the top smaller dia is 35mm and the bigger diameter is 138mm with a height of the cone is 80mm... I think this can be doable on rotary axis of CNC machine... I just need to know did you see the eggbot extension programming in Inkscape...They fill the color and pen can be replaced.. i only want the same but on the conical surface... how can i do it ..any help ?...
I will also look onto the robot do u have more detail of it..
