Cura 3 Beta - Please test the new Wall Order Optimization setting

[burtoogle 513]

Cura 3 adds a new option in the Experimental section, Optimize Wall Printing Order. When enabled, it will try to print the walls using an order that reduces the amount of travel required. It does not affect the order in which infill or skin is printed. The benefit you will see obviously varies with the number of walls your part has and the number of holes in the part. The more walls and holes, the greater the benefit.

I would be grateful if you could try out this feature and provide some feedback in this thread. Obviously, if a print suffers in quality when using this option it would be good to hear about that. Success stories too are welcome.

When I try to slice: https://www.thingiverse.com/thing:1175684 together with Optimize Wall Printing Order, the engine crashes. Other model do work correctly.

I can slice that no problem - what profile are you using please?

Can you post the bit of the log file that shows the crash?

Using the UM3 profile, I can get it to crash and I think I have found the problem. Just testing a solution now....

As a workaround, turning off Infill Before Walls will avoid the crash.

But this does not happen automatically!

Have same error with UM2 + profile normal

Here is my log

If you disable "Infill Before Walls" then it works.

Yes, it does not happen automatically because it should work OK with infill before walls but due to a bug some models will trigger the crash. I have fixed the bug but it will take a while for the fix to make it into the master source and I do not know whether they will issue another beta with the fix in place.
