THE FIRST SPAWNER
Walk on the spawner and note the coords of the spawner when you are on it. For the X and the Z coords, please round the coord at the .5 ; so that for example, X=-237.395789632 will be X=-237.5 and Z=539.613648928 will be Z=539.5
Only a number finishing by .5 is correct for the X and the Z of a spawner.
For the Y of the spawner, just enter the Y of your feet when you walk on the spawner. The program will calculate the correct Y for you from the position of the feet.

By clicking on compute, the distance between the 2 spawners will be calculated, so that you will know if a double effect XP farm is possible. If it is the case, the coords of the center of the AFK place will be calculated.
