I am sure this is an obvious question. I tried the FAQ & I tried searching this too but could not find an answer. Perhaps it is my search parameters or terms?

Basically, my question is this: If you have an exactly dimensioned PCB to be cnc routed (or any material stock of a specific and required external dimension), how do you accurately locate/position the stock on the work table so the rout starts exactly where it needs to?

I know, this is really entry level. As you can surmise, that is exactly where I am.
