May of once worked but now seems broken maybe a patch changed how it is supposed to function?
Great idea in theory, but does not seem to mine as indicated by the animation in the description.
I mean obviously the animation is sped up to more clearly show it's movement. The problem is the main arm attached to the core ship rotates, but the arm with the salvage beams does not seem to swing as shown, only seeming to move each time the 'ON' button is pressed, as in it will move to a fixed position and stays there until the button is pressed again. No constant rotation as indicated.
Also has a tendency to stop firing and rotating after a while, so you'll be required to keep and eye on it, to restart it when it does eventually stop. Due to the way it works it can be tricky to get it into a position to get it to mine effectively.
Hopefully the creator updates this ship at some point, This is the problem with a game like StarMade. Due to the way the game is patched many ships to download from SMD end up broken, never to be updated.
The way it seems to function and stop, it isn't really a complete or practical AFK miner as it stands unfortunately, may be a good base to build your own rotating miner from though.
