Yeah...quite interesting, and quite expensive some of them, like the UV exposure method and the CNC machine. Not like buying it from the local store or making your own board with toner transfer.
But I have this problem. I see that there's a similar topic on this in the Arduino's archives.
I want to make vias. I purely select a layer, trace something, and then switch with the middle mouse's button to the other layer. Till now, everything seems alright. But when I select again with the left button it does give me the error "Can't set via at layer 16 (x position, y position)".
Something strange I found is when from the menu I select the button via it gives me the error "No vias are defined in the layer setup".
Does somebody know the problem? Is a matter of schematic or of a board's setup? What's the solution?
Thank you,
RobertEagle
