  1. I've recently bought the E3D Revo, so I'm switching nozzles a lot - and having troubles. I noticed that even when I tell Cura that I have a 0.6 nozzle, the wall thickness is 0.8 . Line width changes correctly, I've checked. The wall thickness value is not entered manually, and line count is 1. Shouldn't the wall thickness be 0.6? [edit] Just checked with a default profile and Cura 5.3.1 - still 0.8 . Either I'm misunderstanding something or my settings are completely borked.
  2. I want to use my own profiles, which are based on the defaults with few modifications (wall count, random infill start, type of infill, etc...). It gets a bit messy if the default profiles are always in view - but I don't want to delete them either, in case I want to get back to the originals if I decide my changes aren't good. Happily using Cura 5.1.1 at the moment, in case there's an easy way in newer versions.
  3. I didn't know about Mesh Tools - usually I check it in Meshmixer to see if parts come lose, but with this model Meshmixer acted weird. Guess now I know the reason. I've added Mesh Tools and I get the "not watertight" message. VERY useful extension! OK, I've just checked that particular part - and indeed the trefoil is actually 0,01 mm above the plane. That explains that. I don't really t see WHY it is, though. But the original part also has that defect, so the issue must be old (the current cube is the last iteration of several). I *think* that sometimes Tinkercad gets confused and acts "randomly" when merging objects, especially if they're complex - and I've got a dozen of those cubes in the project, each having 12 sub-objects and so on. I will have to re-check all parts, probably best if I completely redo the whole cubes once I checked the parts. In any case, many thanks again! [edit] To add: I think part of the problem is the "text" shape generator. When I embedd a text in a solid cube, the surface is all wrinkled up in Meshmixer. Either I'm using it wrong or it's creating errors.
  4. Finishing reply - just reprinted the cube with 170° (sliced with Cura 5) - the "e" stuck a bit better (it left a mark when I pried it off), but the whole cube itself easily separated when I pulled it apart. So I blame the filament, I was never that happy with it to begin with. Very likely I'm also doing something wrong, but I don't think it's worth the time to investigate further. I don't plan on buying it again.
  5. There is no message from Cura - is it possible that I deactivated it somehow? Here's the settings:CE3PRO_ScrabbleDice.3mf So maybe I messed them up somehow. What's weird is that I printed the same design with a different material (ProtoPasta Iron Pla) and the letters seemed to stick better. And like I added in my edit, with 170 it seems to stick better as well (still have to try printing the whole cube, though). I guess part of the problem is that the whole design is somewhat complex - lots and lots of little separate forms that are joined together, usually not all at once. Maybe I should unlink everything and join it again all at once.
  6. The "decal" (didn't find a better word) in question is the letter "e", seen in the second picture. The first picture is the layer before it - as you can see, it's simply added on top of the layer (not big enough to print a hol, like the q), and for some reason the "e" won't stick. It gets printed alright, but with the slightest pressure it simply pops off and you don't even see an outline where the filament was. I'm printing with 180°, and tried unsuccessfully with 185 - I don't want to go higher as I fear it'll burn the filament (the smell changed to something burnt already, and I know from previous prints that it's likely to separate some liquid that clogs the nozzle when overheated). Is there a way to force Cura to "integrate" objects like this into the layer before it, like it does when the area is big enough (like the q)? I've checked the design (made in Tinkercad), and the "e" does not float above the layer. The STL does look weird when viewed in Meshmixer, which I don't understand - Cura seems to like it well enough. This is the filament I used: https://www.extrudr.com/en/products/catalogue/dark-wood_2397/ Although the spool I use is a bit old (at least a year, I think). ScrabbleDice.stl [EDIT] I've now printed a shortened version (basically just the top) with 170 instead of 180. Either it's because now I've used Cura 5.0 or because of the lower temperature, but it seemed to stick MUCH better. I'll print the whole cube to see if it sticks this time. (Maybe there's something wrong with the printer at that height?)
  7. Maybe there's a setting for it, or maybe it's been discussed before, but I didn't find it 😞 Situation: I have a model that has a horizontal hole. Support is set to "everywhere", so Cura adds some nice supports that make sure the ceiling is as good-looking as the floor. However, the hole is so small that I can't get the support OUT without damaging the print. On bigger prints, I can use some pliers to tease it out. But in this case, the pliers are too big. Is there a way to have the support go beyond the model? Like a handle so you can pull it out. (Not using support would probably work, but the ceiling wouldn't be as nice, and it's part of a connector so it should be smooth.)
  8. I've now tried all three suggestions - none of them had any visible effect (in the preview, at least). Maybe I'm doing something wrong, but what? Here's perhaps a better picture: The letter-to-be isn't printed yet, and Cura tries to leave a hollow where the "empty" will be - but it's so small that it makes no sense to me. Same goes for the ironing. I'd have to set the ironing inset to a negative value to get it to cover everything - but then it'll likely ruin the edges.
  9. I've also submitted a feature request on GitHub, but I can't upload pictures there, so I'm adding a thread here as well. https://github.com/Ultimaker/Cura/issues/6555 Basically, when printing objects with staged "top" layers (think stairs), Cura will try not to create skin whereever there is an additional layer on top. I want it to create skin across the whole layer, because for small prints it's likely a waste of time, and it doesn't look good (with ironing on, for example). Here's an example from Cura: The letters in the middle are now one layer high. You can clearly see the outline Cura leaves. It seems inefficient, and the result isn't all that great. But maybe it's merely a customizing issue anyway?
  10. I'm using Cura 4.2.1 (Windows 10). Recently I bought an Ender 3 to go along with my Wanhao i3. For the Wanhao, the nozzle size setting is where I expect it - in the machine settings extruder tab. However, for the Ender 3, the nozzle size setting is not there but inside the filament type selection (the drop-down right of printer in the main screen). Why? I don't really mind either place, but I do like consistency. Wild guess - traditional and/or because those profiles are not from Ultimaker and the location of nozzle size isn't hardwired?
  11. Apart from the obvious, I mean. Are they part of any normal Cura installation, or are they relicts of upgrades because I had a previous version installed? (I honestly can't remember if I had version 2.1 installed or not. The upgrade 2.1. to 2.2 is there, though. ) The progression isn't without gaps, so it could be either way...
  12. (I realize this is a necro, but this posting comes up at top for my google search, so I'm adding my answer.) A way that seems to be quite easy is to save an empty project (File->Save) which will include the printer settings. Then open (again, via File->Open) that project, and you'll be asked if you want to update or create a new profile and printer. Create new and change the settings there. I've done this just now with the new Cura 4.1 , but older versions should be able to do that as well, since there is a comment from 2018 on GitHub: https://github.com/Ultimaker/Cura/issues/3568 [edit] Apparently not everything is copied? I had to set the manual change in the _settings.inst.cfg again. (I've disabled temp control of the nozzle, because I prefer to control that via Octoprint.)
  13. Yes, that seems to work (haven't printed yet, but the GCode clearly has no temp settings anymore). Thank you! It's going from one extreme to the other, IMO, but it does work.
  14. It would be nice if it were possible to disable temperature control for the nozzle, similar to how it is with the bed. I'm using OctoPrint, and I preheat the nozzle - and sometimes I like to try different temperatures without having to re-slice the model, or send custom g-code in-between. I seem to remember that it was possible in previous versions (i.e. old Cura), and there was a discusson on GitHub about it, where it was said that there is a setting somewhere for that - I didn't find it, though, so maybe it's in the underlying json files? In any case, I think it would be useful if the temperature setting for the nozzle worked the same way as for the bed.
  15. I've seen similar issues and never gave it much thought - I assumed Cura is trying to preserve filament. But now that I think about it - and see your settings - I have to assume it's a bug. No solution, though, sorry. [edit]I think this is the same issue: https://github.com/Ultimaker/Cura/issues/1303 ?
