Hello @carlosgalvezp, I'm afraid the model is not good, it needs fixing before it can be printed

Hello @DonaldNaegele, if the brim is too thin, that suggest that the nozzle is too close to the bed on that first layer.

I checked the extrusion rate and line spacing of the skin lines and they agree with what I would expect given the settings you are using.

I checked the extrusion rate when you posted your original message and it looked OK but I will check again to see that the extrusion rate is what I would expect. I'll get back to you on that.

I meant skins, not infill although using wider lines for the infill would probably save time.

Hi @V3DPrinting, I'm sorry I don't have any experience using a 0.8 nozzle so I'm just guessing but have you tried using wider lines. Personally, I use 0.5mm wide lines with a 0.4mm nozzle and get really good results so I'm wondering what will happen if you try using 1mm wide lines with your 0.8mm nozzle? At least for the infill if not the walls as well?

I release a new build whenever I add or fix anything or there are significant upstream changes. I don't have a regular release schedule. The mb-master branches in my github repos correspond to the latest releases. The mb-testing branches are what I am currently working on but they don't always get pushed to github.

Although some Chromebooks can run Linux applications so maybe there is a way?

Freecad thinks your model is broken...

Cura has something better than s3d processes, look up infill meshes, they really let you target specific regions that need different infill settings. If you are using my release, the setting for enabling the wall gap fill is the same as the Ultimaker version.

Thanks. The problem with the OS X build is simply that the Mac Book I have is too old. As far as I am aware, the codebase works as well on OS X as it does on the other platforms. It just needs someone with a more modern OS X machine to take my source and do the build.

Right now, that's how Ultimaker Cura behaves. I have an alternative implementation of the wall gap filling in my Cura releases that doesn't shake your printer to death. My releases (which can be installed alongside the standard Cura) can be found at https://www.dropbox.com/sh/s43vqzmi4d2bqe2/AAADdYdSu9iwcKa0Knqgurm4a?dl=0 Sorry, only Windows and Linux are currently supported.

Hello @RoboDLC, please save the project file (File->Save) and attach the resulting .3mf file to this thread. Thanks.

Great, glad that helped.

Hi @shiftux, try increasing the value of bottom skin removal width.

Yes, this behaviour cannot be turned off. It was introduced when Cura became multi-threaded. Sorry, I can't remember what version that was.

Set the file type to gcode in the drop-down menu?

Hello @naten11, it sounds like you have upgraded Cura from quite an old version because for some time now the behaviour has changed to what it does now. i.e. it always starts the layer at the same location irrespective of where the previous layer finished. It now behaves this way because the gcode for the the layers is computed concurrently rather than sequentially so it doesn't know where the last layer finished when computing the gcode for the next layer.

That's a kind offer. Building Cura isn't terribly difficult. The best place to start is to clone Ultimaker's cura-build-environment repository (https://github.com/Ultimaker/cura-build-environment) and build that and then build the cura-build repository. If you can get through that, it's then a simple step to build my version. I don't mess with the UI so it should work OK.

Thanks for the test object. I am happy to say that my current release handles that OK. I am sorry that I can't make an OS X release for you.

Thanks for the file, I sliced it and looked at the gcode and, so far, can't see anything obviously wrong. It simply looks like over-extrusion. Have you checked the filament diameter?

When you save the sliced data to file, choose the file type to be gcode...

Yes, that's not good. Unfortunately, that OS X version is rather out of date now but I can't build a working OS X release anymore on my ancient Mac Book. If you could share that model, I could at least check my current implementation to see if it can handle that better now. It's still a work in progress.

That's true but, unfortunately, it is necessary right now. Cura doesn't really handle walls that are not an even multiple of the wall line width wide terribly well. And thin walls and the wall gap fill are also problematic for Cura right now. You may wish to try my master branch build (Linux and Windows only) that has a different implementation of the thin wall and wall gap filling so it could work better for your model. My builds can be installed alongside the Ultimaker releases without conflict. You can find them at https://www.dropbox.com/sh/s43vqzmi4d2bqe2/AAADdYdSu9iwcKa0Knqgurm4a?dl=0
