Hi guys, sorry to bother you with stupid questions, I just want to make sure I buy and build a good kit for my CNC Laser Engraver.
I don't know what is better for my parts, I have a 445nm 9mm Diode laser, 2.4A and up to 3W power, and would like to build this: http://robots-everywhere.com/re_wiki....LCheapoSchems with my laser and this is the part where I don't know what to choose between Ramps 1.4 Kit or Arduino Uno (like this: http://www.instructables.com/file/FZZV3YXI3BH8W6U ).

Sorry for my English and I thank you for understanding and all your help !
