Vague "Unable to slice" error

Posted · Vague "Unable to slice" error

Has anyone on the developing team ever thought that the "Unable to slice" error might be a little too vague?

Pretty often I get that error, change one variable so it allows me to slice again, then change the variable back to what it was in the first place, and the error is gone

Might that be the reason? "unable to slice" for no reason whatsoever, so that's why there's no more info in it?

    Will the error get more detailed if I post those?

    No, but my answer might be.

    /w

    It will be especially useful if you tell us which one variable you had to change and then change back again.

    Any variable, just so it lets me (or itself?) try again

    Moving a model and then undoing it by ctrl+Z also does the trick

    Also, /w?

    I think Cura usually colors the parameter red (if it's a parameter).  Otherwise usually the model is outside the print area and has zebra stripes to indicate that the model is the problem somehow.

    Are you insulting yourself by quoting yourself and writing /w?

    I already said it doesn't matter, it's just so it lets me click the "slice" button again

    I do not understand, does changing a variable and undoing the change move the model to a suitable location to print?



    Anyway, my main point (check the thread title) was that the "unable to slice" error might be a little to vague and it could show some useful information instead, maybe the cause of the error?

    @benjamins94 And my point is that cura *does* tell you the cause of the error.  It doesn't do it in words - it does it by colors and patterns.  Red is a universal color for errors/problems.  And if it doesn't that might be a bug so you need to tell us which error got missed.

     

    Again:

    It tells you by turning the parameter red if it's a parameter.

    If it's not a parameter it has other ways of telling you but you are convinced it's a parameter so we'll skip that part.

     

    Now it might be that it does *not* turn the parameter red and if so I'd like to know about it because maybe there is a bug.  That's why we want to know which parameter you changed to get it to slice again.

    Actually the only thing I can think of is if the part is too big to slice and the parameter you are referring to is adhesion type, or brim or something similar where the size of the brim makes the part too big to slice.  Could that be what you are talking about?

     

    I think for that maybe I agree that there should be a text message that lists the parameters that affect the size (I think there 3 to 6 parameters that can affect that maybe).

     

    Look no one is going to fix this if they can't duplicate an example.  If there are multiple examples at least one example will give the developers an idea of other similar examples.

    I think we have a misunderstanding

     

    1.) Cura tells me "unable to slice"

    2.) I move the model, and ctrl+Z to move it back to where it was, and click "slice" button again

    3.) Cura slices without the error

     

    Or

     

    1.) Cura tells me "unable to slice"

    2.) I pick a random variable, let's say "wall line count", i change it from 3 to 2 and back to 3 again, and click the "slice" button again

    3.) Cura slices without the error

     

    The slice button becomes greyed out, so I change the variable (again, ANY of them, doesn't matter) or move the model so it becomes clickable again

     

    I wish I could tell you which error got missed, but the only thing I get is "unable to slice"
    I uploaded the .log files a few minutes after it happened

     

    Will do a screen record next time...

    I have had this happen several times for a while now.  When it happens, there are NO parameters that are red ( At least no VISIBLE parameters).  As BenjaminS94 says, change ANY single parameter, and change it back and you will be able to slice.   Change temp, change it back.  Change speed, change it back.  Change the number of walls and change it back.  It does seem like you could literally change any single parameter, and then change it back.
