Solution resolved-- thanks Greg, apparently I somehow disabled all colors produced under 'Line Type' 🤦♂️
Thanks for your help!

Hello,
I am having a problem with my layer view. Say, for instance, I'm trying to print this 20x20mm cube:
After slicing, I select preview (either in the bottom right or top of screen) and I get this wonky result-
as if the item isn't sliced at all (however I know it is, as the time and layer count is accurate). Furthermore, the vertical slider on the right does nothing, and pressing the play button does show the model, albeit dark gray (even though color scheme is selected as 'Line Type').
When I save the .gcode and reopen it, the file does not show, and merely produces the empty buildplate. I first had this problem on my older version of Cura, so I downloaded the newset version and am still faced with this problem. This error simply happened out of nowhere--does it have to do with my GPU? I might just be stupid and the solution is right in front of me, but please help.
Note: the .gcode file does still work as normal, it's just odd how the layer view doesn't render correctly.

What material are you printing with? ABS? It looks as if coasting might be enabled. If not, you can try changing the z seam setting (Change from user specified to random or sharpest edge) and maybe lower your speed by a smidge.

You probably went to 'Modify G-Code' and enabled Time Lapse. Turn it off, that's only is you have octoprint and want to do a timelapse effect.

"Dark blue = moves (thin lines)"
What's "moves"?
It's the path of the extruder. It looks kinda like stringing, because if you don't have rectraction enabled, then that's what it would look like.

i try to use the mesh tool to repair but my cura keep on crashing & not responding. please help
This happens to me, too. If your file is somewhat greater than 5 MB or something, it starts to get laggy, and at around 10 MB, or again, something like that, Cura crashes because I think, and this is only an assumption, that it reads every triangle on the file and fixes the ones that need to be fixed, so more triangles mean more work. That's just what I think, I'm probably wrong. If Cura crashes, then, I just use Meshmixer to make the object solid, or just leave it be, and if it really needs to be water proof, then I'll just add some layers of epoxy or another waterproof substance inside to block water from coming in or out. When your model is not manifold, it doesn't really mean anything, only that, well it's not waterproof, so get it fixed in Meshmixer or add some stuff later. I'd suggest Meshmixer since that's a helmet and you're gonna be wearing that, so it would be pretty hard to breathe it. I'm not that good in Meshmixer, so for me, there are artifacts which make the item less detailed, but maybe you can find a way around it.

This happens to me a lot too. If this happens, I normally just manually add supports on Tinkercad, or if that's too much work, I just don't do that model. I can't find a way to stop those lines, though, except for increasing the support line distance.
-
Never mind. I just turned on 'Force Layer Compatibility Mode' (Or something like that) in Preferences. Though that does lead me to another issue. When using Line Type or Material Color on anything like that, Cura just leaves it colorless like this (First picture) and whenever I try to go down a few layers (i.e layer 100 to layer 88) it turns blank (Picture 2) and I have to press the play button to get it back, but it still remains colorless and every time I need to check if the infill or what layer the support stops or something like that, it turns blank like picture 2 and it's pretty annoying to have to press play every time you need to see something. Is there any way to fix this?

Is this an update on Cura? My computer updated and now, every time I go onto layer view, you can see through your model and you can't see supports that well because it's stuck on Line Type and I can't change it. How can I change it from Line Type to something like Layer Thickness?

Maybe, for the time-lapse option on cura, instead of pausing when finished layer, it can pause every 30 seconds, or some time so we don't need to buy a Raspberry Pi to be able to do that cool timelapse effect!
However, it might warp a bunch because it paused. Let me know what you guys think! -

If a smaller nozzle brings the layer back then the problem is that the walls are too thin. Period.
Normally the wall needs to be double the line width setting.
You can get away with thinner than this if you check the "print thin walls" option in cura. Did you try that? You still are limited with how thin you can go versus nozzle size. You can thicken your thin walls in cad or you can use "horizontal expansion" to make everything thicker or you can use a smaller nozzle. A 0.4mm nozzle usually prints reasonably well down to about 0.3mm line width.
Yes, I turned on 'Print Thin Walls' and it worked! Yay! Thank you!

I lost track of your issue - I just skimmed everything. Did you check the mesh? This sounds like mesh issues. If you have a tiny hole in your mesh - smaller than the layer height - then when it slices it might miss the hole and the walls are fine. But then if you change layer height a tiny bit, one of the layers might pass through the layer with the hole and now there is a massive section of the layer missing (or the entire layer).
There are basically only 2 possibilities - your walls are too thin (set line width smaller to test for this) or your mesh has errors. Here's how to check your mesh:
cura has a mesh tester and repair plugin - it detects all problems but doesn't fix them all:
In the upper right corner of Cura click "marketplace" and make sure you are on the "plugins" tab and install "Mesh Tools". Then restart Cura. Now right click on your model, choose "mesh tools" and first choose
"check mesh", then choose "fix model normals" and "fix simple holes" to see if those help.netfabb free repair service is here (you have to create a free account first):
https://service.netfabb.com/login.phpHere's another service - drag and drop mesh repair service:
https://3d-print.jomatik.de/en/index.phpYes. I have been using Mesh Tools for a while now, and it's working fine; some need more extensive repair, so I put it through MeshMixer. My layer width, when brought down 0.3 and 0.1 didn't change much, in fact, although it seems counter-intuitive, it looked like there was a larger gap now. Mesh Tools makes the model water-proof at most times, however it does not change the missing layers. I'm still thinking some of it corresponds to nozzle size because when using a smaller nozzle, the layers are all there. Of course, I will try all this stuff. Hopefully we can find the error.
Toodles! 😄 -

It must be one of the settings on my printer. When I switched to UMS5 for a test, no layers were missing. My Ender 3 and Ender 3 Pro probably have something wrong in its settings. I will look deeper into this.
Edit: When I switched to 'Fast' setting in the UMS5, the part didn't show as it did with the 'Fine' setting I used and worked. When I switch to 'Standard Quality' on the Ender 3 Pro it still is missing layers. Very interesting...
I now know the cause. While changing nozzle size on the Ender 3 Pro (For testing), I realized a 0.3 and 0.2 nozzle size didn't cut off any of the layers. Anybody know why?

Thank you, but for some reason, it still is missing layers. This only happens with some items, I just found another item with another missing layer thingamajig.

So in other words, leave layer height at 0.2 and instead site "line width" to 0.1mm just to see what happens (don't actually print that way).

Your Cura is having trouble opening from the application package; having a problem to open the start. Try opening your firewall. I'm not a coder, so I don't really know what's going on, actually, but hope this might help.
-
Got it. Problem solved.
-
Ok, thank you. On my first screenshot above, there was more than just a tiny layer missing, it was a part of the model cut off. I turned off coasting, do you know what is causing that?

Try changing 'Extrude Amount'. If it is low, one it finishes extruding, it starts moving.
Set 'Disarm Timeout' to 0.
-
So in the video, he says that if you touch the control panel, in any way, move it left, or press the button down, it will start automatically. If you are trying to change filament, 3D print the wheel he uses and connect it to the stepper motor. If you try to move the extruder using the control panel, it won't work.
-
I don't think much of it, though. Probably because I don't use pause at height :]
-
Ah, ok.
You learn something new every day! 😄

Get the Mesh Tools plugin and right click, and click on 'Fix Model Normals' and 'Fix Simple Holes'.

Umstieg auf CURA 5 sinnvoll?

Ich spreche kein Deutsch, also verwende ich Google Translate, hoffe, das ist einigermaßen lesbar.
Zunächst einmal habe ich beim Wechsel von 4.13.1 oder niedriger auf 5.1.0 keine Probleme mit Profilübertragungen festgestellt - obwohl es zur Sicherheit ideal wäre, Strg + J zu drücken und Ihre Profile zu exportieren.
Zweitens hat Cura eine Online-Dokumentation aller Änderungen an seinen neuesten Updates, Link zu den Updates von 5.1.0 hier: https://github.com/Ultimaker/Cura/releases/tag/5.1.0
