ColorFabb default settings disable retraction?

Recommended Posts

I bought a spool of orange ColorFabb filament, and this is my first real try printing with non-Ultimaker filament.  I was pleasantly surprised to see that there were presets for ColorFabb, and I used them.  I got terrible results -- oozing, stringing, knotting.


I tried multiple prints varying the print temperature, but saw the same thing.  Then I put my fingers gently on the filament entering the feeder, and noticed that there was absolutely no retraction happening.  None.  I double checked, and "Retraction" was selected in the Cura settings.  So I set Cura to Ultimaker PLA (forcing the temperatures and speeds to be the same as before, and printing worked much better:



Is it possible that there's an error in the ColorFabb presets?  Is there something that needs to be done other than checking the "retraction" box to get retraction going for non-Ultimaker filament?

You should be able to enable it after selecting it. The profile should just be a list of settings to start with, but not locking them. As for Colorfabb, I just use the basic PLA profile and only change the temp to about 195 for the most part.


Edit: My choice of PLA when slicing is based on the color I wish to see the model in. All the PLA settings, as far as I know, are pretty much the same.

To be clear, I'm not suggesting it's locked out.  I can (and did) check the retraction checkbox -- it just isn't actually enabling retraction during the print.  As I said in my first post here, assigning the extruder to "Ultimaker PLA" settings causes the retraction to work, and the ColorFabb prints very nicely.

Here's a screenshot of how I assigned a particular extruder to use ColorFabb PLA/PHA by clicking the "Material" pulldown. 

I did the same but as I said before my Cura didn't ship with such settings with Cura 3.2.0. 


@kmanstudios do you have the Colorfabb option? Maybe they got added with the 3.2.1 release.

I'm a little new to Cura.  Maybe I did clone a profile and modified it, but I don't know how I did.


Regardless, it seems to me that if I have the retraction box checked, then retraction should work.  I'm in the middle of a long print, but I'll try this again, validate the retraction not working, and post the profile.

My apologies -- this looks like pilot error.  I first bought this spool of filament about a year ago, and did a little experimenting with it on a couple of very simple things, and then didn't really use it for any projects.  I think during that initial use I created a new profile, forgot I did that, and then a year later erroneously thought this was an official Cura profile.


I just created a clean, brand new project, used the default generic PLA profile, and retraction works fine.


Again, sorry for the false alarm.

    • "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.
