Before you can use the mark recognizer the XY offset for the camera tool must be calibrated.

When your camera is connected and aligned, select “Calibrate the camera offset…” from the calibration menu.

Place a tool with a sharp point in the spindle of your CNC machine.

Now make a mark on the table (eg. with a piece of paper) and place the point of the tool precisely on that mark as shown below.

After you click “Next” you will see a view from the camera.

Move the camera precisely over the same mark on the table, then click “Next”.

Your camera is now calibrated!
