I'm playing Medieval Engineers now since 1 week, mostly with trial and error. Most of the things worked like a charm but there are some questions after this first phase. First, yesterday i have created a small windmill. The windmill blades are added to a rotor block. On the back of this rotor i have added a round beam and at the end of this beam is nearby round plate made with square beams. Rotated 90° there are a second plate made with the same technique do transfer the horizontal energy to vertical. On this vertical plate a beam goes now down to the ground floor of the windmill to a second rotor. I don't know if this second rotor is needed or not, but it works. Sometimes the edges of the plates touches the other plate and so the whole rotations stops for some seconds, but after a few seconds they drive again. Is there something i can do, so that they don't touch the edges? As a second question, how can i drive the grindstone with this energy from the windmill? The grindstone is so small and i don't find a way to connect it to my system. Then i have seen some blueprints. If i understand it correctly, i can save parts of my buildings or complete buildings with this for later use. But how can i use it? For instance, in find it very complicated to put the windmill blades n place at the rotor. How can i save only the the rotor with the attached windmill blades as a blueprint? Another question belongs to a weather system in the game. I have build my fortress on a high hill and i can hear some wind. Can i use the wind to drive my windmill? What is with rain or water? Are there rivers planed, so that i can build a watermill, where the water drive the mill? Or water for a castle moat and for the plants? Water is for me THE thing which i miss the most in this game. Ahh additionally i have a technical question: Currently I'm playing only in local LAN together with my son. Is it possible to open such a game as a non-dedicated server to the internet, so that other players can join this multiplayer session? What port must i open for this on my router? Or is there a dedicated server available for Linux which i can run on my Raspberry Pi?
