I have recently purchased an SKR 1.4 Turbo which I intend to add to my P3Steel printer. I have an old power supply which appears to have dual outputs [COM COM +V +V]. I want to connect this to the board but the board only has a +V -V connector. The supply is rated at 12 V 15 A which I believe is what is required by the board.
Do I have to connect both +V from the power supply to the +V on the board, and both COM (-V) on the power supply to the -V on the board?
I guess what I'm asking is whether the full 12 V 15 A is only achieved by using both of the outputs together?
