Also! When I hit print, the progress bar only gets to a half cm on the screen and then stays there saying "Heating up..."
I have the Ultimaker 2 extended and have done 3 prints. All worked fine, however, I tried to start a new print and the extruder did not heat up. When hitting the "remove material" button, the extruder heats up and the material comes out. Please help! Things I've tried: factory reset different print removing material and then putting it back in
