Bug in Latest Version of Cura

Recommended Posts

When I scale something in cura,

I'm getting a very strange bug, I haven't tried with other models, but when I load Cura and put in a model and try to scale it to 0.5 for example, something happens with the model that I don't understand, I have attached some picture for you to see, but it basically gives completely wrong scaling info/times. It's hard for me to explain so it will probably make sense when you look at it.

Cura Bug?

Not seeing any problem? Except maybe that what you are trying to print is so thin that some parts might not be printed at all, giving much bigger printing times when those parts suddenly are big enough to print.

I assume what he is showing is that the times seem to jump about:

0.5 scale - 25mins 0.33 m

0.55 scale - 3hr 6mins 5.35m

0.6 scale - 2hr 37min 8.4m

0.7 scale - 3hr 37min 11.5m

Why would printing at 0.55 scale take 6x longer.. And why is 0.6 scale quicker?

This is only an assumpiton on my part.

Print time is driven by many things.

I'm pretty sure the 0.5 scale makes the lines so thin that it will just skip them because the nozzle cant fit in. Look at the layer view

The difference between 0.55 and 0.6 can be that the 0.55 version require a lot more retraction than the 0.6 scale because of so many thin lines. Again look at the result in layer view.

Without the layer view this is just speculations

Oh, I understand!

Thanks,
