How do I determine how many encoder pulses it takes to move on inch on my cnc router?

I recently had my cnc router retrofit, and I can't seem to get the correct ratio settings.  I have a multicam Mg 204 series, and I retrofit it with camsoft. I need to be able to tell the machine how many encoder pulses it takes to move 1 inch of travel.

Assuming it's driven by lead screws: Find the threads-per-inch number for the lead screw. Find out how many pulses it takes to rotate the lead screw exactly once. Multiply.

Very carefully measure how many it takes to go to 12" and then divide by 12.  Do it several times and average the answers.  Your answer should be very close.
