Wiring the power supply, help

Did you see the skr pro page in the instructions? Don’t use the adapter, the wires are included for those whom buy the boards from me for other machines. You will use one as a jumper between the two power rails as shown. Please always start your own topic, the last one was a year old and a differnt issue.
