I am completely new to this, so my question may seem obvious to some. I am having a problem with my Ender 3 pro. It is running Marlin 1.0.1. whenever I try to print the extruder lifts off the plate by about a half inch. before it starts to print. It makes wonderful tangle of plastic but not much else. It looks like it is trying to print the object but it is starting too high. When I tell it to home It also wants to position itself above the plate as well. I have tried adjusting offset but it still does the same thing when the print starts. Any help would be appreciated.
