For some reason when Horizontal Hole Expansion is selected to enlarge a hole other polygons are affected by having the expansion applied to the first 5 layers as shown in the attached image. If I put a single component in cura and apply the HHE the outside is not affected. However if the same HHE is applied to multiple components joined as a card the anomaly occurs. and of course if the HHE is removed the complex component slices correctly. Any thoughts?

Hey thanks for the reply ahoeben! Yes in the simplest form your suggestion should work, but it is a lot of work and added printing time. however due to the nature of the horizontal hole expansion basically working on every internal polygon of the part (which includes circles) I need to be able to select just the polygon to expand. I have attached a picture to highlight what I mean. The attached is one piece and so in its current form the horizontal hole expansion will act on every polygon (marked with the white dots) because each complex shape is a polygon. I still hope to be able to be selective in which polygon the expansion is applied to. This will overcome the inherent design floor in how these 3d printers work and why the holes are smaller in the first place.

The new Hole Horizontal Expansion option in Cura 4.8 is a great feature. However, currently the feature is applied to the entire print, so many non-holes areas that are technically 'a hole' are affected as well (see the attached snippet). In the pic attached the centre shaft hole of the gear is too small (but the outside diameter of the gear is the correct size). So we apply Hole Horizontal Expansion to enlarge the diameter of the centre gear hole 0.6mm. The problem is the outside diameter of the gear is now 0.6mm smaller as the hole expansion has been applied to it as well. Would it be possible to tell cura where I want the Hole Horizontal Expansion applied?? Maybe by applying a mask like in the second attachment. So the shaft hole increases 0.3 but the outside diameter doesn't shrink 0.6mm? Maybe this feature could be applied to a future version of Cura??

Hi all, This might be a stupid question but does anyone know where the 'support blocker' icon has gone in the new Ulitmaker version 4.7.0? Currently these are the only icons from the left toolbar and be buggered if I can work out how to add a support blocker. Any assistance greatly appreciated
