I buy Netfabb, and installed it on a new computer and now I try to connect the Ultimaker. On this computer i did not installed ReplicatorG and i also not installed Phyton yet. Do i have to install that too wenn i only want to use netfabb on this computer? I only installed the Arduino driver, which is installed correctly in devicemanager. In Netfabb i selected ' Ultimaker specific' and selected the right usb com with highest bautrate. I also try to disconnect usb, but i still cannot connect the ultimaker. Anyone can help me out? What im missing out ??
