I am new to 3D printing so this is probably a dumb question.I have a new Wanhao Duplicator I3 printer. I have downloaded the Repetier-Host software to my Windows 7 computer. My PC gave a message that it was downloading a driver when I plugged the printer in for the first time.I am just not sure if I need to download the firmware or not. I assume NOT, but I just want to make sure.Thanks in advance for any help!
