Warning: Provided retractLength '0.75' is not a valid length

I need to add supports for my model but I am running up against this warning and it will not save.

Answer this question I have this problem too

Is this a good question?

I have not made a successful print yet and I am very suspicious about how the support materials look. The supports for the tips of the ears do not look sturdy enough.

Hey @timbreese60, could you share your CANVAS project (instructions here) so we can test it out on our end? Thanks!

Hey @timbreese60, it looks like this error message was resolved, but for anyone facing the same issue, please go to project settings -> extrusion -> retraction distance, and change the value from 0.75 to 0.7 or 0.8.


In terms of supports close to the ears, I would recommend checking out how to paint on custom supports in step 8 here. Hope that helps and please let us know if you have any more questions.
