Hello all. I'm new to 3D printing, just got my first printer, Ender 3 Pro, for my birthday yesterday. I am having a couple of issues with it: 1) When I click Auto Home the extruder goes about 1/16 of an inch in front of the front left corner of the print bed, and about the same distance below the bed. How can I set, and save, the correct Home position. 2) While trying to level the bed I can get the front and back left corners leveled, but the right side is too high, even when the adjusting wheels are loosened. Please help as I really want to get this thing to work correctly.
