Optimize Wall Printing Order stops working when Brim

[Arbitur 0]

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...

With Skirt

 

With Brim

Yeah this sure looks like  a bug.  Can you post this info on github?  You have to create a github account if you don't have one (it's free though) but worth the trouble as this is much more likely to get fixed if you post there and please include the 2 photos:

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.

@smartavionics Ahaha I see, shit happens easy to forget things. Any schedule when 3.4 will be released? Or maybe include just this in a 3.3.2?

Sorry, I have no idea about release schedules but I doubt if it will be in a 3.3.2.
