1. An industrial machine comprising:
a bucket having a main body and a door, the industrial machine configured to maneuver the bucket to dig material;
a dump cylinder having a piston and configured to open and close the door;
a position sensor configured to sense a position of the piston within the dump cylinder;
an electronic controller including a processor and a memory, the electronic controller configured to:
control the dump cylinder at an initial speed from a first position towards a second position to move the door,
receive an output signal from the position sensor,
determine the position of the piston based on the output signal, and
as the dump cylinder moves from the first position towards the second position,
reduce a speed of the dump cylinder from the initial speed based on the determined position of the piston.
