This is my setup, I made everything on my own without tutorials, so my setup could probably be more efficient but I am not concerned about that.
Whenever I am standing in those three positions while my macerator/furnace machine is running I will constantly be damaged, even from 3-4 blocks away. First time this happened I insulated all the copper wire but it still happens, now I just dont take any damage. It's very distracting. I googled everywhere before posting this so hopefully its not to obvious
Thanks in advance to whoever is awesome enough to help me out
