How to Calibrate Plotter in AutoCAD

Understanding Plotter Calibration in AutoCAD

Properly calibrating a plotter is essential for achieving accurate prints that reflect your design intentions in AutoCAD. This comprehensive guide walks you through the steps required to calibrate your plotter effectively.

Step 1: Access Plotter Configuration

To start calibrating your plotter, you need to access the Plotter Configuration Editor. This tool allows you to adjust settings related to how your plotter interprets drawing data.

1. Open AutoCAD.
2. Navigate to the Application menu, usually represented by a large red "A" in the top-left corner.
3. Select “Drawing Utilities,” then choose “Plotters.” This action will take you to the Plotters folder, where you can manage existing plot configurations.

Step 2: Modify Plotter Settings

Once you are in the Plotters section, you can select an existing plotter configuration that you want to adjust.

1. In the Plotters dialog, find the particular plotter you wish to calibrate.
2. Right-click on it and select “Properties” to launch the Plotter Configuration Editor.
3. Within this editor, you can adjust various settings, such as the port connection, media size, and output details. Take note of the options available for:
   • Media: Specify the type of paper or media your plotter uses.
   • Calibration: This includes settings for alignment and scaling.

Step 3: Set the Calibration Parameters

Calibration parameters are crucial for ensuring your plotter functions precisely as required.

1. In the Plotter Configuration Editor, look for options related to calibration or alignment.
2. Set the appropriate values based on your plotting needs—commonly these involve measurements like scale factors.
3. You may also have the option to run a calibration test print that helps establish accuracy.

Step 4: Save the Configuration

After adjusting the settings:

1. Click “OK” to close the Plotter Configuration Editor.
2. Back in the Plotters dialog, ensure your changes have been saved.
3. If necessary, create a new configuration file to preserve the original settings while having a backup option.

Step 5: Test the Calibration

To ensure that the plotter has been calibrated correctly, it’s important to conduct a test print.

1. Select an uncomplicated drawing to test the settings.
2. Go to the layout tab where your drawing is placed.
3. Click on “Plot” to open the Plot dialog.
4. Choose your calibrated plotter from the list and customize any additional plot settings (like scale and paper size) as needed.
5. Perform a test plot to ascertain that the calibrated settings produce the desired results.
