Abstract:
CNC Router systems have been around for a while; their popularity is rapidly growing in all areas. This is probably due to the impressive capabilities of these machines. Offering the ability to create complex shapes that would take a skilled worker much longer time.
In the last years, there have been an increasing number of businesses and hobbyist invests in routers systems. Many people, however, are still in the dark as to what these machines do and how they work.
Router bed and gantry structure designed according to standard wood board size, stress and strains. Main items like spindle, stepper motors, encoders, gearboxes and screw shafts selection calculated according to suitable ratings to avoid over or under rating witch will increase the cost or cause machine failure.
Breakout board is designed to interface between computer and power board, spindle inverter, emergency stop button, feedback encoders and limit switches. power board designed to receive position, speed, acceleration and direction from breakout board and generate the suitable axes stepper motor poles magnetizing sequence. Feedback signal encoders installed in the design to send position, speed and direction to computer through breakout board to make the control system closed.
