Improved my experience gen by changing out the cobble gen for my new model. Was able to simplify the structure quite a bit and make it smaller and better looking. As usual signs tell you what speeds and su are needed. And remember to put lava in the tanks and the smelting chamber, and flood your pumps with water.
I have consistent problems with this farm. If I don't hit the lever to power down when the two bottom-most chassis are all the way toward the left side, the farm completely breaks.
