When you first open the UI there is a reminder to make sure you are connected to the same network as the hub and printers to use the UI. Otherwise, you won’t be able to communicate with the system.

After clearing the reminder you will see the My Environments screen. This screen is where you can save different printer layouts.

• To get started you need to make a layout.

1. Type your desired environment name in the input field.

• 2. Press the plus icon button that is next to the input field or press ENTER.

Now, you’ll see your environment included in the list. You’ll also see three action buttons which are in charge of the following.

1. Environment Name

2. Rename

• As its name states, it renames the environment selected. This functionality includes error checking for cases in which we provide the same environment name as other created environments or names with more than 25 characters.

3. Layout Settings

• This button opens up another portal that allows users to configure their desired workspace layout. After configuring the layout the environment will be activated and ready to open.

4. Delete

• This button deletes the environment selected.

To continue, click on the layout settings button.

The layout settings opens the workspace layout screen.

• This is where you configure your printer layout for the slicer.

The workspace layout has five elements.

1. Drop down for layout presets.

2. Number of printers in X direction (side by side)

3. Number of printers in Y direction (face to face). This has a maximum of two.

4. Confirm your settings.

5. Save to current environment and close workspace layout screen.

Once you have set up a layout, a new button appears alongside it in the list.

• This button opens the environment.

Environment Selection

Open

The upper bar of the UI shows the current environment you have selected.

• You can click the folder icon to be taken back to the Environment selection screen to select a different environment, change the settings of the current one, or make a new one.

Navigation Bar

Open

• To the right of the current environment, there are six icons.

Upload file

Hub Watcher

Gcode Sender

Slicer Settings

Printer Calibration

Updater

• This section details the use of these buttons.

• This button opens a panel to send the current build plate to the Hub for processing.

• There are two checkboxes in this panel.

  • Auto send to Printers: If checked the hub will upload the processed gcode file to the selected printers automatically, there is no reason to uncheck this unless you are bugfixing the hub.

  • Enable Supports: Needs to be checked if you are printing a file with a slicer profile that has supports enabled. The hub processes files with supports slightly differently than without.

• The Job Nick Name box allows you to name the print job to change how it shows up in the “My Print Jobs” list.

• The Upload button at the bottom of the panel sends the build plate to the hub.

• Opens up a panel with three general sections.

• At the top of the panel you can see:

  • The UI IP is the IP address the UI is on.

  • The Hub IP is the IP address the hub is on.

  • To the right of the IP addresses is a box that you can input the IP address and ID of a hub if it does not auto-connect and connect to it manually.

  • Below the IP addresses the drop down lists all previously connected Hubs to allow you to switch between them.

  • The Reconnect button will try to reconnect to the hub selected in the drop down.

  • The ReSearch Hubs button will search the network for a Hub.

  • The Reboot Hub button sends a reboot command to the connected hub.

  • The Shutdown Hub button sends a shutdown command to the hub.

  • The Update Hub button sends an update command to the hub.

• To the middle of the panel there is a list of process names with an icon next to start and stop buttons. This is the list of process nodes on the hub and their status. If they are shut down a symbol will be next to it and if they are running a symbol will be next to them.

  • PreProcessor: Handles the processing of uploaded files.

  • Maincomm: Handles the coop logic for each print job. This node cannot be started manually as it is launched by the user hitting the “start print” button.

  • Interweaver: Takes the files from the Slicer Node and post-processes them into the final gcode files that will be sent to the printer.

  • Recovery: Handles the recovery of the hub in case of failure.

  • Slicer: Slices the files output from the PreProcessor.

  • Scanner: Scans the network for communications from the UI and connected printers.

  • Chuck Checker: Checks the output of the PreProcessor node for missing sections of the file.

  • Slicer Checker: Checks the output of the slicer node for missing sections of the file.

  • Interweaver Checker: Checks the output of the Interweaver node for missing sections of the file.

  • Printer Calibration: Handles the printer calibration functions.

• At the bottom of the hub watcher panel are two buttons.

  • Start Hub Nodes: Sends a command to the hub to start all the nodes. (Note that the Maincomm will not start with this since it is only started with a print job.)

  • Kill Hub Nodes: Sends a command to the hub to kill all started hub nodes.

Gcode Sender

• This panel allows you to select a connected printer to send individual gcode commands to it.

Slicer Settings

• There are a set of buttons at the top of this panel.

  • Import slicer config to UI.

    • Note: To keep a compatible slicer configuration, please modify an exported slicer config instead of importing a completely new one.

  • Export slicer config from UI.

  • Save current config to UI.

  • Delete clears the config from the UI.

  • Get Config’s From HUB downloads the current configs on the Hub.

  • Send Config’s To HUB sends the config in the UI to the hub.

The Printer List is a panel on the left of the UI that lists all the printers currently connected to the hub.

• This panel allows you to see the status of each printer, what area of the environment they are assigned to, and gives you access to some basic functions for the individual printers.

• This is a drop-down list that allows you to select which build area the printer is assigned to.

  • For a single printer print, this is just selecting which printer will print the model.

  • For a coop print, this is assigning the placement of the printers next to each other, and must reflect how the printers are physically set up.

• This is a page each printer has in the printer list and is accessed by clicking on the name of the printer.

• This panel holds the following functions, listed top-down.

  • printer status

  • printer position

  • hotend temperature

  • bed temperature

  • setting hotend temp

The center section of the UI is the workspace.

To the left side of the workspace is a row of buttons. The functions of these buttons is detailed below.

The main area of the workspace is the 3D environment where you will set up print jobs.

• Opens file browser to upload a STL model into the workspace.

• Exports the current workspace as an stl file.

• Deletes the currently selected model.

• When a model is selected, this switches the model gizmo to move mode for dragging the model around with the mouse.

• When a model is selected, this switches the model gizmo to rotate mode for rotating the model with the mouse.

• When a model is selected, this switches the model gizmo to scale mode for stretching the model in each axis.

• Scales the model to the largest size that fits on the bed.

• This button centers the model in the build volume in XY and places it on the bed in Z.

Model List
