How to Use CI Local Mode

In this document, we will explain how to prepare a file for 3D printing, load filament, and initiate a print job.

Prerequisites

You will need the following prerequisites in order to use CI Local Mode:

  1. STL file. STL is the standard file format for 3D printing, and is an export option in virtually all CAD software.
  2. Slicer software. In this tutorial, we will use Cura as the slicer software. Cura may be downloaded here.
  3. SAAM connected to network.
  4. Spool of PLA.

File Preparation

In this tutorial, we use Cura as our slicing software. Other popular slicing software that you may use include Simplify3D, Slic3r, and more.

  1. Open Cura on your computer.
  2. Open your STL file in Cura.
  3. Select SAAM.
  4. Select your material. In this tutorial, we use Generic PLA.
  5. [Optional] Select layer height, infill density, support material, and adhesion options as desired.
  6. Click Slice.
  7. Click Save to File.
  8. Your file is now ready for 3D printing.

Loading Filament

  1. Access CI Local Mode software in your web browser.
  2. In the Connect tab enter the following settings then click Connect.
  3. Serial Port: /dev/nvprinter
  4. Baudrate: 250000
  5. If filament is already loaded, skip steps 4 -
  6. Go to the Control tab and click Motors Off
  7. Go to the Temperature tab and type in 200 to the Tool Target Temperature entry field. Click the check box to raise the nozzle/extruder temperature.
  8. Wait for the Actual temperature to reach the Target temperature.
  9. Place the filament spool on your spool holder and feed filament through the guide tube until it appears above the print head.
  10. Go to the Control tab and enter 50 into the entry field under Tool to set the extrusion length to 50mm.
  11. Click on Extrude.
  12. Insert the tip of the filament into the print head so that it engages. Once it is engaged, press the Extrude button again until filament is seen coming out of the nozzle. If the filament feed stops moving, but the extruder drive is spinning, click the Retract button to remove the filament and ensure that the filament is as straight as possible then attempt steps 9 - 10 again.
  13. Once you see plastic coming from the nozzle, you are ready to print.

Loading a Part to Print

  1. Access CI Local Mode software in your web browser.
  2. Scroll to the bottom left and select “Upload.” Load your GCODE file output by Cura.
  3. Select your file from the list on the Octoprint page and select the last icon, “Load and Print.”
  4. You should see the state change from Operational to Printing.
  5. Your part is now 3D printing.
