So I recently got a geothermal mk2 up and running, and since the MFE puts out 128 Eu/T, I needed some stronger cable. I made 2x insul iron, and attached it to the geotherm, and it attached to the machines OK, but as soon as I tried to put something in the extractor it disappeared. I didn't get an explosion sound or the stuff inside back, so I'm not sure if it exploded or not.
Do I need to somehow scale down the power for low-tier machines?
