Cura 3.4 "Brim Only on Outside"

[klaus_kraemer 3]

This setting seems buggy:

 

Look at both screenshots - I only have changed the "Brim Only on Outside" checkbox. No other parameter has been changed.  Look at the differenc in printing time between both settings! Why should an inside Brim like that take about 2 days and 6 hours, while the print with "Brim Only on Outside" set takes only 2 hours???? 

 

 

(And in the following screenshot additionally look at the printhead movements with the magenta print material seemingly leaving the printer for an all but endless journey...)

yep.  you definitely found a bug. it's a funny one also, I just tried and every time you toggle the "brim only on outside"  button you get a new time estimate.

 

thanks, I reported it here;

Maybe more of a CURAEngine bug?

I just had the same problem: when I unchecked 'Brim only on the outside', print time went from 4h to days (the time varies wildly between tries: 12 days, 7 days, roll a dice substract 7 and add the age of the captain...? ) and the brim lines suddenly extend to infinity and beyond:

 

 

Cura 3.4, same problem on Win8.1 and Win10, printer is a UM3E and is alone, no multiple build plate enabled (someone mentionned it in the github thingie).

 

The problem does not happen in Cura 3.3.1.
