I Received a Homing Error

Loading and unloading filament can help to align the nozzle correctly.

On the control panel, navigate to Filament > Load Filament. If you’re having trouble, hold the Smart Extruder+/Smart Extruder in place and try to push the filament through. You may want to grip the filament with a pair of pliers to help you push. 

Then choose Unload Filament

Can you start a print without receiving a homing error now?
