Hello I am also very new to 3D Printing and could really need some help. I am trying to convert my Cubex(1Printhead). I bought the following Material:

3D Drucker Teile Titan V6 Bowden Extruder Voll Kits mit NEMA 17 Stepper Motor Für 1,75mm/3mm e3D V6 Makerbot 3D drucker.

Rampen 1,4 Kit Mega 2560 R3 für arduino + RAMPS 1,4 Controller + 5 stücke A4988 Stepper Fahrer Modul + PCB Heatbed MK2B 3D Drucker kit.

My questions so far: 
1)can I use the two Y motors paralel(one normal, the other one +-swapped)?
2)Is there a difference between the romba board and the raps i have got(because both use malin)?
3) is there a malin config i can use?
4) do i need to replace any ohter hardware?

I hope someone can help me
