Optimize Wall Printing Order stops working when Brim

Recommended Posts

Posted · Optimize Wall Printing Order stops working when Brim

Im running Cura 3.3.1 on Windows 10.


I've just noticed that Optimize Wall Printing Order stops working as expected when Brim is selected instead of Skirt.

I've noticed when OWPO works properly it draws all lines for the same walls in one go without travel, but when selecting Brim it prints one line at a time,

so it goes to the first wall, draws one line of that wall, travels to the next wall and draws one line, travels back to the previous wall and draws the second line etc...


Pictures illustrating what happens:


With Skirt


With Brim

    This regression in 3.3 has already been fixed. The story is that the optimization didn't get the wall ordering right in a particular set of circumstances that included brim being printed and so someone decided that the best thing to do was to completely disable the optimization for the first layer when the brim was enabled. What should have happened instead was that the problem in the optimizer was investigated and fixed. That has now been done so service should be returned to normal in 3.4.
