Power Distribution and Controls System Architecture
System Architecture - Power Distribution Wall Outlet DC Power Supply 12-36V, DC 120V,60 Hz X Motor Driver Y Motor Driver Z Motor Driver Wall Outlet Main Logic Board 120V,60 Hz Breakout Board 6V Palm Router
System Architecture - Controls Breakout Board - Processes design file, converts file to motor control signals Main logic Board - Monitors all systems (ie halts operation if vacuum table is off, interlock open) Vacuum System Main Logic Board Computer USB Breakout Board Interlock System Motor Drivers - Takes motor control signals and amplifies to usable form to drive motors Router Motor Driver - Takes signal and modifies it for variable speed Router Motor Driver X Motor Driver Y Motor Driver Z Motor Driver
Router Speed Control • Radial motion in our machine will accomplished using a palm router. Different speeds are required for drilling and milling. Here are some options being considered: • Modifying router circuitry • Microcontroller: Using a microcontroller with PWM channel and H-bridge configuration.
