I had a thought. On the old ramps the top two terminals said 11a, while the bottom two said 5a. Since they come from the same power supply, I thought they were the same. The wires I ran to the external MOSFET controller have passthroughs that I ran into the lower two power inputs. The question being, are all the terminals coming from the power supply the same wattage/amperage? And should the external MOSFET controller be wired through the top two terminals,?
