I am new to 3d printing, set up my cr-10 and upon initial auto home calibration, printer was to close to wall and hit it. Moved printer away from wall and recycled power to run auto home again but the printer makes a noise as if the gears are getting stuck when the extruder reaches the front left corner. Can't complete the auto home and am clueless how to move forward. Every video I've found does't explain how to fix this as no one is dumb enough to do what I did. Any guidance on this is greatly appreciated.
