Are all the GND prongs from all 6 switches connected to each other and going to GND on the breakout board, or no? And the NC prongs, how exactly are they connected to each other? And to the board? There has to be a diagram somewhere shows this visually, no? I don't know how to wire the switches in series or in parallel. You've stated one switch (home) goes to positive and another switch (limit) goes to negative. I'm still a little fuzzy on how the 6 limit switches physically connect to each other and to the USB breakout board. User response: Thank you very much for this helpful information. Let me know if this information was helpful (or not) by adding information to this question.

Use the settings in software to set whether in NC or NO configuration. If the NC is used, then the the switch is constantly connected until the switch is pushed (engaged) then the connection from the pin to gnd is broken (open). The COM would generally go to GND and the NC or the NO would go to the pin. These connections consist of COM (common), NC (normally closed) and NO (normally open). A typical limit switch has three connections on it. The software configurations for the limits switches are under File -> Settings -> Limit.

Note that you can have more than one switch on each pin where the NC is connected in serial fashion and the NO is connected in parallel fashion (this can be seen on the diagram in the multiple limits switch section). If the origin is in the middle, the negative would be at a little more than the -4 foot end and the positive would be at a bit more than the +4 foot end. The negative end would be the limit switch behind the 0 foot location behind the origin. The positive end would be the limit switch at the end of the machine that, say the machine has a 4'x8' area, reaches a bit after the 8 foot mark. Each axis can have two limit switches: one for the ++ (positive) end and one for the - (negative) end.
