Welcome to the Kicad Users Group. I hope we have some lively and
constructive discussions on this excellent EDA package. I'll start the
ball rolling with a couple of questions of my own.
1. Why does cvpcb exit whenever you save netlist and cmp list?
2. The MOSFET_N component in Eeschema has pins labeled G,D and S
rather than 1,2 and 3 as with regular transistors. If you select a
TO220 package for it in cvpcb then an error occurs in pcbnew when the
netlist is loaded. The error says the pins G,S and D cannot be found.
There is a specific module for one specific component that has a TO220
shape but S,G and D pins. Whilst this works it is confusing.
