If you use the same switch as both home and limit, and set it up on the config page that way, then the 0,0 point will be where the machine stops when you do a ref all.
You can then put the fence werever you want it and do a G54????? work offset, or possibly tell mach what to put into the dros after a home move. SO if the corner of the fence is at .5 and .5 you would put this number into mach on the home/limits page under the config tab page and then once you do a ref all, the dros should read x-.5 and y-.5 I haven't done this yet, but I am pretty sure it can be done.
Then all you do is do your drawing with 0,0 in the correct place and all is well in router land.
as ger51 said, cut measure and then you are good to go.
