Octoprint

3D Printing With Octoprint

The 3D printers in the Fab Lab are all controlled using Raspberry Pis that run Octoprint. Octoprint is a 3D printer controller with a web based interface.

Workflow

Before Print

Upload G-Code

If you are using Slic3r with the profiles that we have created there will be a 'Send to printer' button in the top right settings area that will send the G-Code file to the selected printer. This may take some time if you have a large file.

If you have the G-Code file already you can upload it using the file menu in the bottom left Octoprint interface.

Log in

If print controls are grayed out you probably need to log in. The login prompt is in the upper right, and the username and password are 'maker'.

Select File

Use the file browser in the bottom left of the Octoprint interface to select the file you want to print. Click the folder icon to load the file for printing.

Check Layers

It's always good to check the G-Code Viewer tab to make sure that everything looks like it should.

Change Filament

If you want to change the filament: heat up the nozzle using the drop down on the Temperature tab, activate the release lever on the feeder, and pull the filament out. Load the new filament onto the spool holder, clip the end to a point, and feed it into the machine until it starts to push out of the nozzle. Make sure to use the same type of filament that you specified in the slicer settings!

Start Print

Once everything is prepared, hit the blue print button on the left to start your print. Always watch for at least the first layer to make sure that it is adhering correctly.
