I Don't think So !
Seriously? Use your head...

Check which mobo you have and find the appropriate SF version for your board. You can find a comprehensive list [here. It'll be either the 1280 or 2560.

Reasons to upgrade? Pause at predetermined z position, change speed mid print, change temp mid print, etc. There's more but I honestly don't feel like doing your homework. And since every beginner needs to learn how to calibrate the extruder I created a stickied thread.
