glad to see we made some progres!!
endswitches are limit switches to stop excess travel + and- in each of x, y, z
they can be
a) ignored!
b) connected to microswitches 
c) connected to photoswitches 
d) connected to hall effect switches
basically whatever you have
they can be
a) logic low is good, high is bad
b) logic low is bad, high is good
there is a seting to invert them if they're working the wrong way
in order to "ignore" them to logic high
motor control is used to switch the router spindle on and off
if you're doing this manually, ignore it
panic stop/reset
is used to freeze everything (in case of an emergency)
you can just ignore it (set it to logic high)
panic reset is only checked after a panic, so you can ignore that too
hope that helps
cheers Mike
