I'm ready to send my first board to a pcb manufacturer. I've generated the GBL,GTL,GBS,GTS,GBO,GTO and the drill TXT file using the manufacturer's cam.
Now the problem is that when I open those files with two separate gerber viewers (GERBV 2.6 and Viewplot) I get the same result.. the holes are where they're supposed to, but everything else is placed +0.409 mm from the origin, on both axes.
It took me a while to understand what's wrong, and after that I placed everything in Eagle's Board Editor 0.409 mm right from and 0.409 mm above the origin. After that I generated a new set of gerber/drill files and the problem seemed to be solved. I mean I get the same exact (positive) results in two different gerber viewers.
My questions is why is that happening, if it's normal (like an alignment of the board from 0.409,0.409 and not from 0,0) and if should send it like that.
Can I trust these software viewer that the board would look exactly like that when finished ?
what's bother me the most is that in the second scenario the holes are still at the same coordinates and only the other layers were repositioned (although I selected and moved everything in eagle).
thanks in advance
