Another is that you don't have the right volt/amperage for the motor. not wired right you can change, I don't know that you can do anything about the other when using the davinci mb.

You can on a ramps or Rambo the ramps you use the trim pots to set that or use the firmware to digitally set it depending on the board.

The davinci the output is digitally set, I don't know if you can change it.

So you need a nema 17 that is the same range of volts and amp settings
so what you need to know is what the force and the # of steps per deg of rotation
generally I don't see to many start below 37oz.in/26Ncm 37 and are .4A  (there are some but not many)
then they go up most common are the 1.2A - 1.5A but there are also 2A 2.5A and even some 3A

I don't know what the motors on the davinci are specified to draw

I bought an official davinci stepper from the australian reseller and the morons sent me the one from the x frame not the extruder stepper with the little gold cog, either way this is the only one out of three that has actually worked as it's supposed to.

Now speaking to these morons further they cant seem to find the actual stepper i need so i really wish someone out there could give me guidance as to why this specific brand is working when the others just rock back and forth and don't actually rotate.

so now I have pin 1 as orange pin 2 empty  pin 3 is blue pin 5 is empty pin 6 is yellow.
this reversed my gear direction.

now if you have it pulsating you then you need to swap one set of the pins.
example if I was pulsating rather then turning I would swap pin 1 and 3.  or swap pin 4 and 6. Only swap one of the pairs not both.

it will then spin. if its the spinning the wrong way then you will need to change the pins like I did.

pin 1 is yellow pin 2 is empty pin 3 is red pin 4 is blue pin 5 is empty pin 6 is orange

so it looks like the grounds will be pin 2 and 5
pin 1 and 3 are one pair and pin 4 and 6 are the other pair.
hope that helps

Have you tried running a earlier version of repetier

Also you can have a 4 wire a 6 wire and a 8 wire stepper motor. 

Here is a good description

Not an expert, but when I was doing the Bowden conversion for my 1.0 I also decided to use separate motor. The wiring did not match. Regular Nema 17 should have 6 pins (4 of them are actually used). If you have a tester, check for the resistants between the pins. The one's that make up a pair will have a resistance between them. Now you can take a
da vinci extruder nema motor and test for the resistance between the pins the same way. Connect the wires to the new motor based on the measurements. You only really have couple of  most common connection patters: 1/3 and 4/6 for example. You can measure the resistance without powering the motor.
