	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.

	==Loop==		===Loop===

	In order to effect simultaneous cylinder motion, we divide the motion into segments as a general strategy. Each segment consists of the span between two position-sensor-magnets, with the beginning at one sensor and the end at the next sensor. There are 3 magnets for each cylinder, ordered as +, -, and +, where the + or - corresponds to the state that the magnet induces in the sensor circuit. This means that the initial and terminal positions are defined as +, and the middle position is defined as -.
