 Every well on every piece of labware has three addressable positions: top, bottom, and center. The position is determined by the labware definition and what the labware is loaded on top of. You can use these positions as-is or calculate other positions relative to them.

 Starting in API version 2.16, trash containers are :py:class:`.TrashBin` or :py:class:`.WasteChute` objects. The API calculates movement to these objects based on the horizontal *center* of the pipette, rather than its primary channel (the back channel on 8-channel pipettes, and the back-left channel on 96-channel pipettes in default configuration). This ensures that all tips attached to the pipette are placed over the trash container for blowing out, dropping tips, or other operations.
 
-You can adjust the position of the pipette center with the :py:meth:`.TrashBin.top` and :py:meth:`.WasteChute.top` methods. These methods allow adjustments along the x-, y-, and z-axes (in constrast to :py:meth:`.Well.top`, which only allows z-axis adjustment). With no adjustments, the "top" position is centered on the x- and y-axes and is just below the opening of the trash container.
