You want to feed two filaments into 1 nozzle? The Marlin Firmware can handle that assuming the nozzle can be purged reliably.

yes, that's what i mean. so what must i do?

Configure Marlin to have 2 extruders that are 0 mm apart. And get both of the motors running correctly. At that point, you may need to tell the Slic3r to do some custom GCode to purge the nozzle when you do a color change, but that is about it....

Try MarlinKimbra and see if it can do what you want. It already has native support for this, which it calls SINGLENOZZLE. I have submitted a mixing extruder feature that also does this, but only to the MarlinDev branch, and it hasn't been merged yet. If you like, I can make a branch for you that has the current Marlin plus this feature. It works just like the Repetier Host mixing feature.
