It's pretty straight forward amazing work by this guy no lie.. few simple lines of coding to ease a ton of hard work <3 anyways back to your question ..
Fill out player declaration forum..but make sure you bank preset 1 is saved with 28 of the desired logs to make into planks.
For me i just, adjusted the camera height by pressing the page up & down key so the red dot lands on the saw mill and once you have that right press play :P and works like a charm
for some reason it hits enter or something and begins to type in the chat box .. so i just disable smart and click the emotes tab and then re-enable smart this prevents it from typing at all.
hope this helps
