Connect to the Computer

Instructions on how to test connecting your machine to the computer

Motherboard

  1. Connect your LumenPnP to your computer using the motherboard’s USB-C port.

  2. Manually move the Y gantry all the way to the front of the machine, and the X gantry all the way to the left.

  3. Plug in the power supply to power up the machine

  1. Now, it’s time to check and see if your computer recognizes the motherboard. We’re going to use CNCjs to check this, but feel free to use any other tool you’d like. Download CNCjs, install it, and open it.

  2. In the Connection widget, select the Marlin tab.

  3. Click the refresh button next to the Port dropdown, and click the dropdown to see if your computer found the board.

    • If you’re on Windows, the port should look like COM1 or something similar
    • Mac should look like /dev/tty.usbserial00000
    • Linux should look like /dev/tty.ACM0
  4. Keep the Baud Rate at 115200, and click the Open button. If you see boot text enter the Console widget, you’ve successfully connected to your LumenPnP!

Cameras

We also need to check connecting to the cameras. CNCjs has a webcam feature, so we’ll use it for this test too.

  1. Find the Webcam tab in the bottom left of the window

  2. Click on the module using the little slider icon

  3. Open the widget using the carrot icon

  4. Finally, click the gear and look for detected webcams in the dropdown under “Use a built-in camera or a connected webcam”. You should find “PnP Top Camera” and “PnP Bottom Camera” in the dropdown. Select each one and test out the camera feed.
