Cura 2.4 / 2.5 Can't Slice More Than 3 Parts

[peterbrown77 0]

I am trying to make a batch of identical parts. They're very simple washers. Any more than 3 of them and it says "Unable to Slice because none of the models are in the volume" ... which is patently untrue.

Any ideas?

TIA

More info - I find if I set it from "one at a time" to "all at once" it will do a dozen but quality is definitely a factor in how it behaves. Make it too fine and it won't slice.
