I sent my first set of files to an outside fab house to get some proto boards made, and after checking the gerber files with gerber view, it appears that there are 5 or so vertical lines going through the back copper layer that don’t appear in pcbnew.
They DO appear in the 3d viewer…This happens only on two of my boards(one was started from a copy of another), but not on some other boards I’ve checked.
The lines appear to not be part of the layout, because if I move the layout around in pcbnew, the extraneous vertical lines don’t move. Using this as a workaround, I sent another set of gerbers to the fab house with the lines outside the edge cut layer, so that SHOULD be OK.
Since this was my first manufactured pcb, I was unaware that it was a problem. The homemade pcbs I did for the same design didn’t have any extraneous lines.
Anyone have any ideas what the hell is going on? I’m using stable release v4.04 on windows10.
