Retraction

Recommended Posts

Noob question.

Printing with MakerGeeks Maker Series PLA. Duplicated the pre canned Cura PLA profiles. Printer is a new UM3. Things look great but getting extra material oozing when making larger moves. I have tried a wide range of temperatures and it doesn't seem to make a difference. So assuming I need to move to retraction settings next. It appears that there is no retraction values set under the material profiles in Cura.

Question is if this is the next logical step to combat the oozing, and any recommendation on some starting values to input on the material profile for a UM3?

Good luck. I came here searching for the same answer. I'm honestly not too impressed with Makergeeks Maker Series PLA. The Black HD Glass filament was a giant pain in the butt and was string city. I am testing a Makergeeks silver at  6.5mm at 45mm/s retraction, and it still hasn't improved much.

Whilst you temp. is not making a difference for you, you must try and print as cool as possible. Reduce you temp until you get under extrusion then back off 5 degrees.

 

My retraction settings (for PLA) are 

Distance 5.5mm

Speed 50 mm/s

Minimum travel 1.0mm

Maximum count 90

Min. extrusion distance 0.2mm

 

This is not to say they will be the best for you, you should do some tuning but maybe they give you a start.

 

Important to realise that filament impacts this; i.e. your settings which work well for one filament may need some tuning for another filament (even sometimes the same filament type e.g. PLA from the same manufacturer) - not usual but can happen). In my limited experience I would say that different filament types, e.g. PLA vs Nylon may well need tuning.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
