- Control knob (Taz 6)
- Print surface / print bed
- Lead screw
- Tool head
- Hot end
- Filament holder
- Cooling fan(s)
- Wiping pad
- Identify the differences between the Taz 6 and the Mini
- Identify the X, Y, and Z axis
- Prepare the bed
- Wipe down with isopropyl alcohol
- Confirm nozzle wiping pad is clean
Models and Slicing
- What is the name of the software used for preparing models for the printers? (Cura Lulzbot Edition)
- What kind of file types can be loaded into Cura?
- What is the difference between saving for Cura and saving for printing?
- How does Cura handle inches versus millimeters?
- Demonstrate the ability to set up a print:
- Set material type
- Set the correct quality / speed profile
- Confirm the model fits on the print bed
- Confirm the model is oriented correctly
- Basic understanding of supports and why they may or may not be necessary
- Can manipulate the model and view in Cura
- What is infill?
- What are the build plate adhesion types and why are they necessary?
- Can preview the printed model by changing the view from Solid to Layer
- Know how to get to the Octoprint web page via the wiki
- Can login and generate an API key for Cura (this is fine if it’s already done, just confirm knowledge)
Connecting to the Printer from Cura
- Connect to the Mini and set the temperature via the Monitor tab (requires connecting to Octopi)
- What kind of filament type is recommend at the CMS (PLA)
- What is the diameter of the filament used by the CMS printers (2.85mm or 3mm)
Load and unload filament

- Identify parts related to loading and unloading:
- Idler retainer
- Hinged idler
- Drive gear
- Hobbed (ridged) extruder bolt
- Feed hole
- Hot end
- Complete load or unload process
- What to do if the printer is not extruding?
- Check idler retainer springs (to* tight, to* loose)
- Check hobbed bolt (contact shop lead)
- Contact shop lead
- Describe the expected machine response when a print is started
- Describe the expected machine response when a print is in progress
- Describe the expected machine response when a print is finished
- How do you remove a print?
- Clean up
- If both printers are available, which should you use? (The smallest one that can print your part.)
- How is scrap / waste filament handled (Trash can. Only leave a failed print in the shop if you have shop lead permission.)
- Honor box instructions
- Reporting problems (yellow tag outs, email address)
- Resource scheduler
- Where is the fire extinguisher?
