	Correct zeroing occurs in most cases. If the machine was turned off in the far-right-position, this code does not work properly. This is an artifact of the control mechanism, and cannot be avoided easily. The user needs to reset the machine if this happens. To determine if the machine is zeroed properly, observe the position of the drawer during the initial 5 second rest (after zeroing occurred). If the machine did not reset properly, reset it manually via the reset button on the Arduino shield or by cycling the power to the controller.		Correct zeroing occurs in most cases.

	The code as of 4.22.10 is shown below. This code operates with two position-sensor-magnets, where the concept was to avoid using 3 magnets for simplicity. This code works by calibrating timing between the initial and mid position of a given sensor, such that the completion of the stroke is attained by timing. It turns out in practice that at high machine speed, over 15 gpm, the timing is not robust and errors on the order of up to 1/2" in positioning may occur sporadically. Because of this reason, the code was updated to 3 position-sensor-magnets for each cylinder, such that timing is avoided.		The code as of 4.22.10 is shown below.
