Top and Bottom Camera

Your LumenPnP has two cameras used throughout calibration and operation.
Top Camera: Looks downward at the machine's work area and is used for locating fiducials and identifying positions.
Bottom Camera: Looks upward at the nozzle tips and components for accurate alignment.

Step 3 of 14

Locate the Device dropdown.
Select the LumenPnP top camera.
Locate the Format dropdown.
Select 1920 x 1080, 30 FPS, MJPEG or an equivalent 1920 x 1080 resolution, as an alternative option.

Step 4 of 14

Click Test next to the Capture FPS setting.
Allow OpenPnP to initialize the camera.
Confirm that the top camera preview begins displaying a live image and removes the red X from the top camera feed.
The image may initially appear dark or completely black. This is normal if the exposure settings haven't been adjusted yet.

Step 5 of 14

To ensure exposure settings are applied correctly, locate the camera properties

Locate Exposure in the camera properties.
Check the checkbox under the Auto column.
Uncheck the same checkbox to disable automatic exposure.
This switches the camera back to manual exposure mode and helps ensure the setting is applied correctly.

Step 12 of 14

In Machine Controls, locate and select the Actuators tab and click on LED
A small window will pop up. Set the Boolean Value to ON.
This turn on the LEDs for the top and bottom camera.
Then close the window, and switch back to the Jog tab when finished.

Step 13 of 14

The initial exposure settings were a starting point, and may be fine. Now that the top and bottom lights are on, adjust the Exposure for the top and bottom cameras until the camera produces a clear image without excessive brightness, if needed.
For now, use whatever stationary area is visible, or your hand, in the camera preview to use as reference while adjusting the exposure.

Fine tuning the Exposure

A good exposure should allow the camera to distinguish objects clearly without washing out important details. We can make more precise adjustments when positioning and calibrating the bottom camera, if needed.
