Modify filament changing options on Ultimaker 2

[sotakuma 1]

Good day to you all.

 

I wanna know if there´'s a way to make the printer to extrude filament before reversing/changing the material. I'm using an all metal E3D V6 and I'm having problems every time that I want to change filaments, it just get stuck, the only solution that I find do far is to extrude some filament first then lunch the change filament option.

 

Do I need to change some parameters on Marlin to make this permanent? I'll love to use the same menu option inside the printer.

 

My machine is an Ultimaker 2.

 

Thanks.
