Okay here is the 3.4.1 version. Can't see the problem on that version either. layer_thickness.curaproject.3mf

99% of course; 100% infill makes no infill but uses top/bottom everywhere. I'm on master, so I don't think you can use my project files. If your problem keeps ocuring I suggest you make a new issue at github.com/ultimaker/cura and fill in the complete issue template.

If a (part of a) layer is too thin to be printed at the 0.3mm layer height it will print it at the normal 0.15mm layer height. I don't have any problems with Infill Layer Thickness here on the master branch, though... I have infill printed every other layer for the most part of my angled cube.

No. Sadly not. Implementing regularity across layers with different geometry is rather difficult.

The layer below shows how the black is receding where the back of the helmet should be white: (In blue so that you can see the black)

Hmm. It should work better when you have the gray regions as part of the 1 mesh for white and the 1 mesh for black. If you keep just 2 meshes there will be less boundaries on the inside of the mesh. If you use my method to model the gray region as a separate mesh you will get wall lines between the gray and the white or black regions. That's a waste of material.

I cannot reproduce your problem in Cura 3.4.1. I tried making the whole body in both colors and there were no layers where the color wasn't swapped to the other color. If it keeps persisting in your model you can try setting the Horizontal Expansion of one of the extruders to -0.01mm.

Nono, the layers are automatically made non-overlapping due to the Remove Mesh Intersection setting.

You don't need to cut the model into layers, Cura already automatically does that for you by default! Just load the part where you want to alternate color twice and set one instance to the one nozzle and the other instance to the other nozzle. Make sure Remove Mesh Intersection and Alternate Mesh Removal are both enabled and also verify that Top Layers and Bottom Layers are even numbers to prevent them becoming solid. Verify these settings for both nozzles. Here's what the layer view looks like for a model similar to https://www.thingiverse.com/thing:1421443 The eyes are in both colors.

Oh yeah; that's right!

It's in the Infill category and it's called 'Infill Support'. It is just a setting.

You seem to have forgotten that the following features were also contributed by @bagel-orb: Infill support. Disable omitting retractions in support. Support wall line count. Ahem! #humblebrag

Your problem is not specific to the path planning algorithms. See comments in the ticket.

Implemented it! You can follow the progress here: https://github.com/Ultimaker/Cura/pull/3411 You could beta test the next release; the Cura team doesn't really distribute pre-beta builds...

I could probably implement this without too much effort, but the Cura team is lagging behind on handling github issues and pull requests, so I fear it would take too long. If you respond to this thread again I might give it a shot tomorrow.

Maybe you should update to Cura 3.2. This problem is about something which only happened in the Cura 2.3 beta thing.

Yeah. There's now a setting called Initial Layer Line Width.

I totally agree. That thing is way too large and has way too much detail. It should just be a cone which points at the location in the layer. For feedrate visualization the color scheme goes to orange rather than red, which results in intermediate colors of poo-brown, which I dislike. It would be really nice to have (target) temperature visualization - especially for dual extrusion. And fan speed visualization would be nice as well. As for the rest I love the new layer view options.

Hi, I'm BagelOrb a.k.a. the engine guy a.k.a. Tim a.k.a. that dude with the beard which is better than that of SandervG. I work on the inner workings of the slicing engine which actually generates the gcode from the 3D model data. This requires a lot of knowledge of both hardware and firmware and of course of Cura itself. In the next couple of years I will be researching slicing advanced geometry which goes beyond the scope of an STL: texture information, infill density heatmaps and similar 3-dimensionally defined data which cannot be captured in a surface mesh alone. In my free time I like turtles.

There's not really an easy documentation. Currently you can only run it by compiling the feature_texture_processing_rebased_newer branch of CuraEngine yourself and running it directly from the command line. Here's an example CuraEngine call:

Those small pieces of support are being recognized as small overhangs which require support towers. You could disable support towers or reduce the support tower diameter in order to prevent this from happening.

PS: which features from Craftware would you like most in Cura?
