- a second gear 711b of the gear train is disposed in an axial bore of the first gear 711a.
- a third gear 711c of the gear train is adjacent to the second gear 711b.
- the shaft 713 extends through an axial bore of the third gear 711c.
- the motion of the motor shaft 709a causes the first gear 711a to rotate.
- Rotation of the first gear 711a induces rotation in the second gear 711b which, in turn, induces rotation in the third gear 711c, thereby driving rotation of the shaft 713.
- the rotation of the shaft 713 causes the inner burr 715 to rotate relative to the outer burr 717 rotation of the inner burr 715 about a longitudinal axis of the inner burr 715. This relative motion results in the grinding of coffee beans contained in the space defined between the inner burr 715 and the outer burr 717.
- the grinder motor 709 is operatively coupled to the controller of the beverage machine 200.
- the controller is configured to start the motor 482 that rotates the electro-mechanical rotor 406 in the hopper 202 to initiate dispensing of coffee beans from the hopper 202 into the chamber 708a.
- the controller is configured to start the grinder motor 709 to commence grinding of the coffee beans that have been delivered into the chamber 708a.
- the amount of time between the starting of the rotor motor 482 and the starting of the grinder motor 709 can be, for example, less than about 1 second, between about 1 and about 10 seconds, or greater than about 10 seconds.
- the controller is configured to monitor the change in the weight of the hopper container 202a using information received from the load cell 474 as coffee beans are dispensed from the hopper 202 and thus also as the coffee beans are ground by the grinder 708.
- the controller In response to the controller detecting that the weight of hopper container 202a has changed by a predetermined amount, the controller is configured to stop motor 482 to halt the dispensing of coffee beans.
- the controller is configured to allow the grinder motor 709 to continue running for a predetermined duration after rotor motor 482 is halted to ensure that all of the beans delivered to grinder 708 are ground and that no unground beans are retained in grinder 708. In various implementations, this predetermined duration is between 1 second and 15 seconds, for example about 2 seconds, 3 seconds, 4 seconds, 5 seconds, 6 seconds, 7 seconds, 8 seconds, 9 seconds, or 10 seconds.
- the burrs 715, 717 are arranged in a carriage 727 that, in turn, is arranged in an axial bore of a fourth gear 723b.

- carriage 727 includes one or more pins 727a that extend radially outward from an external surface thereof and the fourth gear 723b includes one or more tracks 729 formed in an inner surface thereof.
- Each track 729 in the inner surface of the fourth gear 723b is helical, although each track 729 does not necessarily extend completely around an entire circumference of the inner surface of the fourth gear 723b.
- Each pin 727a of the carriage 727 is slidably seated in a track 729 of the fourth gear 723b.
- the adjustment motor 725 is configured to rotate a fifth gear 723a of the second gear train.
- the fifth gear 723a is engaged with the fourth gear 723b so that rotation of the fifth gear 723a induces rotation of the fourth gear 723b.
- the rotation of the fourth gear 723b is in a horizontal plane.
- the fourth gear 723b does not move upward or downward during its rotation.
- the rotation of the fourth gear 723b causes the pins 727a of the carriage 727 to slide within tracks 729 of the fourth gear 723b. Due to the helical nature of the tracks 729, the sliding of the pins 727a in the tracks 729 causes the carriage 727 to either move vertically upward or downward, depending on the direction in which the fifth gear 723b is rotated.
- the movement of the carriage 727 moves the outer burr 717 vertically upward or downward relative to the inner burr 715.
- a diameter of the inner burr 715 decreases in an upward direction due to the frustoconical shape of the inner burr 715. Moving the outer burr 717 therefore allows the grind size of the grinder 708 to be adjusted.
- the higher vertically that the outer burr 717 is located relative to the inner burr 715 the coarser the grinder 708 will grind the beans using the outer and inner burrs 717, 715.
- the lower vertically that the outer burr 717 is located relative to the inner burr 715 the finer the grinder 708 will grind the beans using the outer and inner burrs 717, 715.
- An uppermost position of the inner burr 715 corresponds to the coarsest grind
- a lowermost position of the inner burr 715 corresponds to the finest grind.
- the motor 725 is operatively coupled to the controller of the beverage machine 200. As explained in further detail below, the controller is configured to operate the motor 725 to adjust the grind size of the grinder 708 based on information including order information received from the user via the user interface 236.
- the adjustment of the grind size of the grinder 708 is automatic and driven by an electric motor.
- the grind size of grinder 708 is manually adjustable by a user.

- the control unit of the motor 725 can be configured to adjust the angular displacement of the motor 725 based upon the identified range of encoder values. As the angular displacement of the motor 725 changes, the grind size setting of the grinder 708 also changes due to the operative coupling between the motor 725 and the grinder 108.
- the motor 725 can be configured to rotate at full duty until the encoder communicates encoder values within the identified range of encoder values that correspond to the determined grind size setting, at which point the motor 725 can be commanded to stop.
