LulzBot FAQ

Welcome to the LulzBot FAQ. As a reminder, LulzBot printers are highly customizable so be careful of all settings. There are almost too many questions that can be asked to make a good FAQ page. Here is a starting list of FAQs:

 

What are the basics of the TAZ6?

- FDM printer, 2.85 mm. Build volume: 11" x 11" x 9.6"

- USNA uses Cura for LulzBot then OctoPrint.

- Several different extruders available.

 

What filaments can the TAZ6 use?

- The TAZ6 prints 2.85 mm filament and can print almost all filaments currently available in the market.

- Different nozzles and extruders might be needed though for some filaments.

 

Which extruder should I use?

- The Aerostruder is the most versatile extruder and the one that we will use the most.

 

Can I change the extruder?

- Yes, but this requires a firmware change on the printer (please change this LulzBot if you are reading). Ask MakerSpace staff before changing extruders.

 

Can I and should I change the nozzle?

- Nozzles are very easy to change and can be changed. Usually the only needed change is a new (cleaner) nozzle or a strong nozzle such as a steel nozzle.

- The LulzBots should have a sticker on the extruder indicating what nozzle is installed.

 

Do I need to use a raft/brim/skirt on the TAZ6?

- We normally do not use a raft since build plate adhesion is not normally a problem on the TAZ6.

- We normally do use a brim or a skirt and both are reasonable and do not normally cause problems.

 

What do I do if I get a probe error?

- Probe errors are normally due to filament being on the nozzle exterior preventing good electrical contact during the probing process. So all that is normally needed is to clean the nozzle. The printer tries to do this on the wiping pad (and is usually successful unless the filament is really clogged on the extruder).

- The best practice is to watch the printer go through the probing process. It is very simple to understand once you watch it once. The printer checks 4 different locations on the printer for alignment purposes. It does these checks at 2 different speeds at each location.

 

Do I need to put glue on the build plate?

- Cura will recommend glue for certain materials, but in general putting glue on the build plate is helpful. That said, we very rarely have build plate adhesion problems on the TAZ6s.

 

I cannot find my filament in Cura, what do I do?

- You can create custom materials in Cura. The most important settings are printing temperature (which will then affect several temperature settings) and build plate temperature. If you get this correct, the printer will normally work.

 

My filament keeps breaking during printing, what do I do?

- Many filaments become brittle when they absorb moisture which then may lead to filament breakage.

- We have filament drying containers to dry out filament. These containers can even be used during the printing process (often very good for ABS). We even have a custom filament dry storage container that mounts to the TAZ6 designed by a 2019 Capstone team.

 

My part is stuck to the build plate, what do I do?

- Using glue uses actually helps this, but if this is your question, it is too late to add glue...

- Often reheating the build plate can help remove you part. Cura even has a setting that is normally enable to keep the build plate warm, but we normally do not use this setting because keeping the build plate hot for an extended period of time is not desirable from a safety perspective.

- The best bet is to use 2 "spatulas" one under the other to try and pry the part off. Do this on multiple sides of the part and the part will usually come off.
