It is worthy to once again note that the M8084 parameter only alters the "logical" zero position of the platen. The hardware physical "zero" position remains as determined by the Z-Axis limit switch and the "flag" at he base of the Z-Axis trolley.
When the "Platen Go Home" (my apologies to E.T.) button is pressed, or when the printer is initializing before a print job the platen will always descend to the physical limit switch determined zero position, and then rise to logical "zero" when firmware receives a g-code "goto zero" command.
