since the owner of this schematic has been silent on Reddit and i wanted to get it to work i have made some modifications to this : https://www.reddit.com/r/CreateMod/comments/105umjz/smart_tree_farm_improvements_schematic/
i have got almost all of the filters and stuff working, there is still an issue with the gantry systems as i can not get them to work consistently (they only work on and off - on goes back and forth and stops and then when you turn it off it then does it again) the redstone links will need to be set to the saplings (i forgot to do this part)
if there are any other issues with this (other than mentioned) please let me know and ill try and sort them.. if you know how to solve the gantry please do and re upload so everyone can benefit!
