Z Motor Pins on RAMPS

Hello all,

I'm in process of building Prusa Mendel i3.

There are two z motors, and the RAMPS board I got in my kit has two sets of pins for z motors. Does anyone know if these pins are actually connected to each other?

The reason I am asking this is that my z motors came with a shared connector. If these pins are connected to each other, I can just plug this one shared connector to one of the sets, but if they are not connected, then I should split the connectors and connect each motor to each set of pins - driving two motors with only one circuit will be too much load.

I wish I can check the other side of the circuit board to see if each pins are connected, but there's another board under the top one (where the pins are located) so I can't see it. Am I ever going to move one of these z motors independently from the other one? Or, even if I am not going to do so, is the firmware and the board capable of controlling each z motor independently? If yes, then that would mean these pins are not connected. However, unfortunately, I haven't gotten to a point of operating/calibrating my printer yet, so I don't know...

Does anyone know?

Thank you!

Well, it didn't take me too long to find the RAMP circuit diagram, and I can see those two z motor pins are connected in parallel. In other words, I can plug the shared connector for both z motors to one of the pins.

I wish I have searched it before posting my question. Sorry about that.

Thank you.

yes but if your using marlin and ramps 1.4 and not to confuse you even more if your only having one hotend why not put your othe z on your e1 pin although just found out no benifits to doing so lol, so thats me changing my configuration around again
