New to eagle and PCB design, i have some simple questions

Former Member

so im trying to design a very simple OR gate safety, shown here (max amperage is 11)

but when i try to generate the board view all i get is this

    looks like the signals are not properly connected to the symbols.

    try moving the symbols and look if the signals stay attached.

     

    Maybe your symbols are not on grid?

     

     

    besides that, your or gate is missing the power supply connections.

    You most likely need to use the invoke command on that part.

     

    Don't know what your Q1 & Q1 realy are. If they are not logic level

    input power moduls but plain npn transistors, that circuit won't work.

    Indeed - in fact :

     

      if you look at the ugly diagonal wires to X3-1, X2-1, X2-2 it's quite

    clear that they go to the middle of the symbol and not to the connection

    point

      the wire to X5-1 doesn't even reach it

      the wires to the rest of X5 are to the middle, not the connection point

     

    and so on

     

     

    Did you use the "wire" tool (which is for drawing non-signal lines) to

    make them, rather than the correct "net" tool?

    thank you for the help my Q1 & Q1 are npn transistors i used them because i only want there to be a connection between x4-1,x5-1 and x4-4,x5-4 only when there is something going from the 22-23-2031s, if i can't use  npn transistors what should i use. also how does one exactly invoke command?
