C. Dispense Head Controller
1. The Dispense Head Controller manages dispense head processes and
input/output. These include:
Valve speed and acceleration control
Control of Camera Lighting
Control of Height Sensor
Control of Needle Heaters
Control of Pneumatic solenoids
2. Even though the software can have direct control over conveyor operations,
the majority of the time the dispense controller acts independently.
3. Like the 555 conveyor controller, the heart of the 555 dispense head
controller is the MPC-555 microcontroller.
The controller receives commands from the software through the CAN bus
for direct I/O control and changes in system configuration.
CAN is also used for updating software with the status of the dispense
head controller operations.
