Power supply and motor driving for RAMPS 3d printer controller
I want to buy a RAMPS 1.4 controller board for my arduino mega.
First, I saw that there are 2 inputs for power. one is for 5 amps and the other is for 11 amps. Now, my 12v @ 15 amps power supply has 2 output ports each giving out 15 amps. how would I attach my power supply to the RAMPS board. will anything bad happen if I attach 12v @ 15a to both the ports of the RAMPS input? If this will work I think it will be a
good option (if nothing will happen) because I think my load uses more than 5amps. How would I wire this up?
I already have 4 drivers (not pololu ones) for my steppers which control step and direction and power up the motors (not through RAMPS). I want to make use of what I have so is there any way I can use my drivers with the RAMPS board?
Thank you for your time and help.
