Printing one by one

[falc 6]

small question.

Is there a proper way to change the order in witch objects are printed when using the one by one option ?

if not, might be a good feature to put into cura

No there's not.

actually I would also like it in 'all at once' for custom wipe towers..

Usually it's top right -> bottom right -> top left -> bottom left

I just do it that way. But sometimes it depends on the height of the object and I haven't figured out how it chooses.... But you can start with that and just look at the slice view to see where it's going first.

It's reasonably complex how it makes the decisions. It uses multiple (different) head sizes and tries to find a configuration wherein all of these are printable.

It uses multiple (different) head sizes

 

How does that work? I would assume it used the head dimensions as set in the machine settings?

[nallath 1,120]

Yeah. It uses the machine head size with and without fan brackets. These sizes are then used to make a minkowski sum around the convex 2d poly (the shadow that is visible) of the object. Based on the which of those polys intersect what you can figure out if there is a solution. It simply stops at the first solution that works (so it can sometimes give weird sequences)

thanks... I had to wikipedia that one

Oh right, sorry. It's such a common thing in computer science that I sometimes forget it's not that common in other circles.
