Cura 2.7 problem with scaling

Recommended Posts

Hi there I have a problem with cura 2.7, when I try to scale an object it looses outside walls (see attachment) in this case when I scale it to 37% it has all walls but at 36% it looses outern walls. This isn't happening to all objects but is very annoying. I checked the same model in ideamaker and slic3r and it scale without any problem even to 20% but I prefer to using Cura.

Thanks for any sugestions :)

There is a minimum part thickness that can print. Typically if the nozzle is .4mm the minimum wall width is around the same I believe with cura 2.7.

Try changing ALL the line widths to .3mm for a .4mm nozzle (that's about the minimum you can go down to and still get reasonable quality). Or consider using a .25mm nozzle.
