Note: this method works best with setting the first layer height as 0.2mm

Also, if you can't move your nozzle below 0 in the Move Z menu, send the following GCode command to your printer from Pronterface or Repetier Host or from the Terminal tab in octoprint:
M211 S0
this will disable MIN Software Endstops.
