    When the printer moves to the Auto-Home position it is supposed to be up against the end-stop switches.  That tells the printer that the XYZ are at absolute 0.  The print head should not be able to move below a Z of absolute 0 (because the switch is there as a stop).

     

    From that point in space, wherever the print head moves in the XY plane the nozzle should still be at 0.  When you level the bed you are adjusting the bed to the nozzle so the plane of the bed matches the plane of the nozzle.  When it's correct, the top of the plate is also at Z=0 (or usually a paper thickness below the nozzle) and there should never be an interference.

     

    Does that printer have Auto Bed Leveling?  If it does then you need to set a Z offset.  That makes a fine adjustment between where the end of the probe is and where the nozzle is in relation to the probe.

    If it does not have ABL you need to practice your leveling.  I use parchment paper.  It's only .04 thick and nothing sticks to it.  There are actual leveling prints you can use to move the head around the build plate without having to constantly putz with the LCD.  I think CHEP has one.
