This document lists the test procedure steps for the “smoke test” for the Cura LulzBot Edition software used with the Lulzbot 3D printers.
The “smoke test” is a short (approximately 15 minutes per test configuration) go-no test that is performed on new builds of Cura on a regular basis. It does a basic sanity test to ensure that the build installs, launches, basic UX features work, and a short test print can be made.

- LB-TP-0002, Aleph Objects Cura LulzBot Functional Test Procedure
The tester requires a basic knowledge of how to operate the LulzBot 3D printer including hardware configuration, loading filament, removing print from the bed, cleaning the bed, and safety issues. Refer to the appropriate manuals listed under References for more details.
On the Mac platform you will need to change a setting to allow installing applications that did not come from the app store:
For macOS 10.11 (El Capitan):
- Launch System Preferences from the dock.
- Select Security & Privacy.
- Click on the lock icon and enter your password.
- Select Allow apps downloaded from: Anywhere
- Close the settings dialog.
For macOS 10.12 (Sierra) and 10.13 (High Sierra): You will need to first download and try to run the application before changing the settings:
- Launch System Preferences from the dock.
- Select Security & Privacy.
- Click on the lock icon and enter your password.
- In the General tab you should see a message such as “Cura was blocked from opening because it is not from an identified developer”. Click on “Open Anyway”. MacOS will then note the developer and add it to its internal list of identified developers. If you download a different app from the same developer, Sierra will look for the developer on the list and if it sees the developer, the new app will open.
For more information see:
On Debian Stretch, the sudo program may not have been installed during OS installation. If not, run these commands to install it and add the current user to the group allowed to run sudo (replace <username> with the name of the user account used for testing):
su (Enter root password when prompted)
apt-get install sudo
deluser <username> floppy (Works around 10 group limit per user)
adduser <username> sudo
The following hardware and software is required in order to perform the test procedure:
- A Lulzbot Mini or Taz 6 3D printer with USB cable.
- A desktop or laptop computer with display and mouse.
- The Cura software to be tested.
- Suitable filament (e.g. PLA).
- STL file for loading: rocktopus.stl
- STL file for test print: OpenHardwareKeychain.stl
- A known good 3D print of OpenHardwareKeychain.stl printed with the High speed profile.
The tester should have read and be familiar with the Start Here and User Manuals, including the safety instructions at the start of the User Manuals. Heed the warnings about possible electrical shock hazard, burn hazard, fire hazard, and pinch hazard. Do not leave the 3D printer operating or powered on when unattended.
On a weekly basis the following maintenance tasks and checks should be performed:
- Wipe clean the smooth rods.
- Clean print surface with isopropyl alcohol.
- Check that the hobbed bolt is clean of filament.
- Check tightness of belts.
- Clean hot end off any buildup of extruded material.
- Check if the nozzle wiping pad needs to be replaced.
- Clean bed leveling washers.
- Blow out any dust from the cooling fans and control box.
See Section 3, Maintaining Your Printer, of the User Manual.
Test failures should be reported on the Cura board at (//https://code.alephobjects.com/project/board/10///). Select “Create Tasks” and enter the information about the issue. Be sure to include the following:
- A meaningful title
- A description that includes the software version, hardware used, test that failed, expected result, observed result, and any other information that may be helpful.
- Enter “Cura 2” under Tags
Leave the Assigned To, Status, and Priority fields at their default values. The bug will be reviewed and assigned to a developer. Monitor the bug so that you respond to any questions that the developer may have about it, and retest it when a fix is made.
It may sometimes be useful to include log files when Cura crashes or produces an error. The log files can be found in these locations (the version number, 3.2 below, will vary):
Mac: /Users/<username>/Library/Application Support/cura-lulzbot/3.2/cura-lulzbot.log
