Have a look at Lightning infill, it might be close to what you want. Alternatively instead of using 0% infill you could hollow out the model and use regular supports. Or create an overlap modifier in Cura and set infill only inside that modifier

I might be wrong, but shouldn't you have quotation marks around the STL file path? There's a space in it C:\Users\blv\Desktop\stl files\200_stars.stl ^ right here

@Philsim1212 People have had some success with an external tool for this, see the thread below. It's not exactly what you ask for (feature of Cura), but it might help

@guate6 We've lost one of them so a colleague modelled it and then we found it again. Here's the model for it, untested though, so I can't guarantee it'll fit EDIT: Uploaded rougher mesh model. What on earth is my colleague's mesh-export settings... Uvolnění airmanageru.3mf

@greens83 I might have some workarounds for you, if you'd be willing to make the extra effort. Regarding printing bottom part of the model regularly and the top in spiralize, you can do this by setting the whole part to spiralize and increasing bottom layers. The "bottom layers" part would be printed solid (no infill), which may or may not be acceptable. The other workaround is to slice each part separately and splice the gcodes together (I imagine a script could be written to automate this) or modify them to start at the height of the previous segment. Lost in Tech has a video about this. None of is it as good as what you're asking for, but if you really want to use new Cura for you prints it might be worth the effort.

@hako Yes, Cura 5 (beta and full release) work just fine for me. I would be quite surprised if no one at Ultimaker used Cura with two monitors (using only one is such a pain for me now..)

I don't want to speak for the devs out of turn here, as I don't know them and haven't even read the bug reports in question, but I imagine it might not be as easy as "a test with two monitors." I've used Cura from I think 4.10 on about 7 different computers, all with 2-3 monitors (few quite old work stations at work, couple of new ones and two custom built PCs, all with very random assortment of monitors) and never had a crash like this. I don't even want to imagine what pain it'd be to try to debug something PC setup dependent Also, I love the new engine. Is it not called Arachne anymore, was that just a temporary name while it was still in pre-release development?

I have an AA0.4 with 4200 hours and 4600 meters of filament and an AA0.8 with 1100 hours and 3500 meters. Quite a while ago I had a look at the nozzles under a microscope and they weren't even close to being circular. Instead of replacing the whole cores I just replace nozzles, it's actually pretty easy (I have good experience with UM3 Brozzl nozzles). This is a nice guide for print core disassembly:

I believe they might be talking about support interface. Take a look at the options Enable Support Interface, Support Interface Density and Support Interface Pattern, that might be what you're after

@DanPrinterMan There is something you could try, but I have no idea if it would work, and if yes then what the quality would be. You can slice it in Cura with tree supports, export the gcode and then try to convert the gcode back into stl. There's been a thread about it recently and someone linked a tool that should do it. I haven't tried it myself, so I can't say if/how it works, but if you want to give it a go, here's the thread Also, about the bulkier than expected tree supports, look at Thomas Rahm's new implementation. I've had some great prints with their version. https://github.com/ThomasRahm/CuraEngine/

You can do this, with a bit of a workaround. If you manage to get the print sequence in the right order, you can go into the machine settings and edit the gantry height. Cura will then think the machine can safely print tall parts. It can be a bit risky though, especially if you forget to change the gantry back.

@3dprntz You can still monitor the print with the UM camera (tested with UM5). The button is still there, it's just missing its icon. You just have to remember where to click

If you disconnect the material station the weld-together route might work quite well, since if it breaks apart it'll be much easier to get back out. If you don't want to weld do remember that you'll still have to throw away the material that's in the bowden tube, so you won't get that much from all the pieces left over

Ahh.. I didn't think of that. I'll try to remember the next time I see it happen. Thanks.

I guess I could contact our reseller who provides support, but as it is I don't really have much to tell them. So far I've seen it hit the print only two times. If only I remembered which prints it happened with so I could try to print the same gcode again and see what happens. Regarding the lowering of the second core, I don't quite remember how high it sits, but perhaps it is done so that you never extrude from the second print core in the high position to prevent possible extruded plastic curling upwards and going through the hole in the silicon cover and up above it? But as I said, I don't quite remember how much the nozzle stays in contact with the cover in the up position
