1. A horizontal door guide for a vertically stacking door, comprising:
a first track and a second track to vertically stack panels of the vertically stacking door along a horizontal line;
a drive shaft coupled to a bottom most panel of the panels to lift the vertically stacking door vertically;
a Geneva drive shaft coupled to the drive shaft; and
a lifting cam coupled to the Geneva drive shaft, wherein the lifting cam comprises a rotating lever to separate and lift adjacent panels of the panels of the vertically stacking door as the vertically stacking door is opened in a vertical direction by the drive shaft and to push the panels into the first track and the second track, wherein the rotating lever comprises a spring flex allowing rotation of the rotating lever relative to a drive member of the lifting cam during operation to provide a tolerance for timing an insertion between pins of the adjacent panels.
