@GregValiant thank you for taking your time and diving into this problem. It's interessting because I can't recall ever setting this feature, must have happened in dire attemps to fix some problems in the past 😄 Setting the initial layer to 0.35mm was also one of this attemps as in the past I had massive problems with the first layer sticking to the print bed. Since I use a glass bed and 3DLAC no such problems occured so 0.35mm on the initial layer is in fact not necessary anymore. Thank you also for analysing my model. I am no material engineer or designer and never learned those things. So every bit of information is highly appreciated. I never considerd the stresses that occur on the 90° angles and on the tubes. As the STL indicates this is V2. V1 is doing it's job since October, so I can access some experience with it. The tubes are simply there for holding brushes, so the stress they transfer to the tubes aren't that high. I am sure that they will hold even when not attached to the back wall. But I will consider it as V2 hasn't been printed yet. For the hooks, as you can see, here some more changes were made, I took a good bunch of material away. Before the stress would be distributed over the whole length/width of the organizer but with V2 it solely relys on the hooks. So strenghten these would really be a wise choice and I will definitley look into this. Thank you also for pointing in the right directions with the inside/outside fillet.

@Torgeir & @GregValiant thank you both for testing and verifying that the issue is something in my configuration. I don't know why it never occured to me to simply test another profile, but when I switched to the "Standard Profile 0,2mm" it worked. For research purposes I've uploaded the 3mf file CE5_SinkOrganizer_v2.3mf For my issue I will simply tweak the standard profile (mostly speed and retraction) and roll with it. I'm unsure what could possibly cause this behaviour. At first I thought it could be the first layer height of 0,35mm, but another PETG profile of mine has the same configuration and with this it is slicing correctly. Anyway thank you all for your help. BR, Loki

I checked with the Arachne Beta but it happens there as well. Same result shown in the screenshots. All the walls are 2mm in thickness and the connectors between the hexagons are 1mm in thickness and 2mm high. And it gets correctly sliced at the second layer and on. Only 1 layer too high. What baffles me the most is that it does it even when submerging the model well under the bed. I deactivated "Drop model to buildplate" and lowered it to -1mm and the layer view showed the same image as in the screenshots but naturally only for 4 layers instead of 8. Maybe as a sidenote: this also happens when no support are generated. I attached the STL, maybe so we can rule out a general error and that it's only on my side or not. If necessary I can also provide the F3D or the OBJ file. SinkOrganizer_v2.stl

Hi everyone, I am at a loss and after many hours of googling I can not find any help to my problem. It was hard to come up with a title for the thread, but basically my problem is that when I am slicing a model I made in Fusion360, what is supposed to be the bottom of the model only starts printing at the second layer. I double checked the model and it has a perfect flat surface, I even aligned it with the bottom plane and made sure that everything is correct with the model. I tested with PrusaSlicer and there the first layer get's sliced correctly. But as I have all my conifgurations in Cura and need specific features from it, I don't want to go through the hustle of using another slicer. But I assume when PrusaSlicer can correctly slice it that the issue is not with the model. This is a screenshot of the model in Fusion360, as you can see, according to Fusion the whole bottom is one (flat) face. I also tried several of Curas features ("Lay Flat", "Align Face") but the issue persists. Even when lowered -0,2mm beneath the buildplate the hexagonal cutouts do not get sliced. And the parts that do get sliced are slightly thinner than the should be. First import an alignment After "Lay flat" and alignment: Layer 1: Layer 2: I would really appreciate help on this matter. As the model barely fits the buildplate, I cannot use a raft so I am highly dependend that the first layer goes down as perfect as it can be and a Z difference of 0,35mm isn't helping with that.
