The first step is to mount the CNC controller board to the control enclosure. Users should ensure that the controller is securely fastened. They should also note that the mounting must have easy access for wiring.
Connect the Motors
Users should identify the motor outputs on the controller. After that, connect each stepper or servo motor to its corresponding output. Those using servos should have a separate servo drive. Why? Because it will interface with the controller. Users should label each cable to avoid confusion during the installation process.
Power Supply Connection
Next, they should connect the power supply to the controller. They should ensure the voltage and current ratings of the power supply are compatible. After that, connect the positive and negative terminals to the appropriate power input terminals. This step will supply power to the controller and its components.
Mechanical Components
The next step is to connect the mechanical components. For example, the users should mount the spindle to the Z-axis motor. They will then connect the motor to the relevant port on the controller. Users of external devices like routers will have to employ a relay or Z-plate to connect to the controller. This relay will turn the router on and off depending on the signal sent from the controller board.
Limit Switches
Here, users need to connect limit switches to each axis. The switches should be mounted near the estimated end of travel. After that, connect the wires from each switch to the corresponding input terminal. This setup will prevent over-travel situations by cutting servo power when motors reach the switches.
Main Components
Users should then connect the main components. They should connect the power input for the C11 CNC controller board to the primary components.
