System Manager
The system manager software provides the overall control and decision making functions
that are used by the system during all operations. User requests are received from the
Display Driver (in response to button pushes). The requests are processed and commands
sent to the Controller Board to activate the appropriate hardware.
Move Compiler
When “start part” is requested the system manager activates the move compiler. The move
compiler retrieves the cmb file from the top of the queue. The cmb defines the tool path for
the part on a layer by layer basis. The move compiler calculates the proper extrusion rate for
the road thus combining tool path and extrusion. The resulting motion control is saved in a
PCB file.
Feeder
This driver takes the output of the move compiler and feeds the motion control information
to the Controller Board on demand. The feeder will typically start before the move compiler
has finished the calculations for the part. This eliminates waiting for all calculation to be
complete. As the Controller Board executes the motion control commands they are removed
from dual port memory. The feeder adds new commands as space becomes available.
Event/Command Monitor
This software handles all non-motion control interactions between the SBC and the
Controller Board. Events are printer status information being sent to the SBC. Commands
come from the SBC telling the Controller Board to do something such as find home.
