Badly built? Wow, that's a hell of an assumption. For your information, the two plasma generators that failed to work until I shut off the factory are connected to 4 MFSU's that (at the time) were almost completely drained of power. My setup is a set of disconnected, dedicated to purpose machine setups with all movement between machines controlled by routers and tesseracts.
So... the specifics are 2 plasma generators, 4 MFSU's and 4 automatic recyclers disconnected from everything else. MFSU's are almost without power, generators have plasma in a can but it refused to fill the internal tank or generate power UNTIL i shut off other generators, at which point they fired up without intervention.
