Is your feature request related to a problem?

Lets assume we have two objects, Obj1 and Obj2. The current logic prints in this order:

1. layer 1 on Obj1
2. layer 1 on Obj2
3. layer change
4. layer 2 on Obj1
5. layer 2 on Obj2

Which printers will be beneficial to this feature?

All

Describe the solution you'd like

To decrease travel distance and total print time, it would make sense to print in this order:

1. layer 1 on Obj1
2. layer 1 on Obj2
3. layer change
4. layer 2 on Obj2
5. layer 2 on Obj1

to further improve this idea, the logic for the "next" object could be calculated be the distance from the current object position, in case you have more than 2 objects. the closest start point of the next object should be the next printed object.

As far as I know that had been discussed and be concluded that it will make worse surface finish due uneven cooling.

But I've not seen any evidence or tests that prove that conclusion.

[Scootworks]

that can, of course be an issue, but for many parts, that wouldn‘t be an issue at all. furthermore, if the parts are different anyway, you might not nitice that issue. you also have the settings for tve cooldown

I agree, may be some check-box for enable this order of print will be great!

[Scootworks]

yeah for sure. I forgot to mention that

I support the idea! So that there was a flag, whoever needs it will enable this option!
