My RAMPS 1.4 board has failed. I bought a RAMPS 1.6 to replace it but :
The old board had 4 power wires that went to 5 A and 11 A respectively. The RAMPS 1.6 has only 1 pair of power inputs. Which pair from the PSU do I connect to the board? Or do I combine them and connect them to their polarity respectively?
I have a cooling fan (12 V) for part cooling. In RAMPS 1.4, I had it connected to the pins between the power inputs and the X stepper driver on the board. The RAMPS 1.6 doesn't have such a pair of pins. Is it possible to connect it somewhere else on the 1.6 board?
