  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 ?
  16. Sorry for the horrible title - I'm sure it's something that is often encountered, but I just can't force my mind to spit out the right words to just explain it in a simple sentence :-( I've tried to search, but what good is all the knowledge of the world, if you don't know how to ask the question... So, here's a picture that demonstrates what I mean: (This happens with the old 15 Cura as well as with 2.4 .) As you can see, the inner bottom (yellow) starts some distance from the edge - because Cura tries to save filament and the empty area is where the walls are going to be. Makes sense, in theory. However, it also means that Cura tries to start the print on empty air - which naturally fails. One way around would be to increase infill until it's tight enough to support the start of the bottom, but I don't want that much infill all through the print (though maybe 2.4 can vary infill? I've still not spent much time with it.) So, how can I solve this? Surely it's not a rare issue?
  17. I downloaded the latest Cura Beta again, and as before, I've to fill out a questionaire. I can see why you'd want to track what your software is used for, but why do I have to answer the same questions every time I download the program? I've even signed in beforehand, hoping I'd avoid it. Sorry if this has been posted before - I tried to search for it, but it seems I can't find the "Search in this subforum" button. (Or the "Create a thread in this subforum" button for that matter. I had to select the forum for this thread manually.)
  18. No replies yet - no one else has this problem? I *think* I may have found the reason, but not the why. These lines seem partially redundant: ;LAYER:0M107G1 F2400 E-1.00000G1 Z0.075 <--- What is this for?G0 F5400 X97.500 Y65.481 Z0.300 Why the G1 move? This must be the double-dip, but what purpose does it serve? I don't think it happens always, just with *some* models I'm trying to print? Also, I know this is an outdated version of cura. I'll switch to the new one eventually, but for now I feel more comfortable with this and I don't want to learn a new Cura and calibrate the printer (the latter is bad enough).
  19. Feature request (or is it a bug?): Can the backend put important messages as popup through to the frontend, instead of merely logging them? Example: "WARNING - No objects suitable for one at a time found, or no correct order found" The slicer stopped working, the frontend doesn't know it. Neither does the user unless he looks into the logs. Getting a popup would be an easy workaround.
  20. In the program folder is a subdirectory "resources\machines" - the JSON files in there are the templates - copy/edit them to change these values. [edit]There's a thread with better details somewhere, AFAIK.
  21. OK, now I have a problem that isn't just UI. I think it's an old issue, I skimmed through this GitHub thread: https://github.com/daid/Cura/issues/771 and it seems to describe the problem I have. Basically: Cura tries to create a surface in preparation of a structure without first making sure there is support below. If there is enough infill to "catch" the new surface - fine. If not, Cura doesn't care and everything drops and leaves ugly holes. Here's a screenshot of a GCode as displayed by Repetier Host 1.6.0 , the GCode was created by Cura 2.1.0 . It shows three layers, the first two only contain the shell and infill, the last one is the preparation for the surface upon which another structure is printed. Quite a few of the lines are actually in mid-air, others may start on a line but end in mid-air, which might work but often doesn't. It seems to me that Cura is trying to preserve filament by not covering sections that are neither built upon, nor visible. Obviously, a solution might be to increase infill until there is enough - but that wastes time, and if I was ever visited by a goddes, it certainly wasn't the goddes of patience... :-D A better solution, maybe it's possible already?, would be to have an option like "close whole surface in preparation of upper structures". (Just find a better name.) I've tried to get that by telling Cura to use more surface layers, but I don't think it had the hoped effect. It's usually not a big deal, unless I try to print something big. -- Unrelated, another minor UI peeve: there is no version number in the title of the program, it only says "Cura", instead of "Cura 2.1.0 beta" or something. -- And another UI comment: Why is the bottom side of the object red? I'm assuming this is to indicate angle, but if it's the flat bottom, it shouldn't look the same as a free-hanging structure, IMO. It took me longer than I'll admit to figure out that the underside is indeed flat and firmly against the buildplate, and not, as I first suspected, somehow hanging in space. -- Finally, an odd bug when resizing/scaling and viewing layer mode: Open an STL file, resize it, switch to layer view. Result: It seems to be visual only, so it does no harm except look weird. Moving the object clears it.
  22. The None option is actually a misnomer in Old Cura. It printed a skirt (which is why we changed that, so it now actually reflects what it does) Would it be possible to add a "zero line skirt" named "none"? I'm not using a skirt, but if I wanted to for some reason, I'd have to change settings back and forth. (Unless I'm the only one who feels that way. In that case, feel free to ignore me :-) -- Another minor UI issue: This may seem a stupid question, but how are the drop-down menues in the setup section (right hand side) supposed to be used? Click-and-hold-drag or click-and-select ? I.e. should one click on a menu, hold the button, move towards the desired entry, release the button, or click, let the menu appear, move the mouse to the entry, and click again? Because the latter doesn't consistently work on my machine. Quite often the menu closes immediately. Also, when clicking the menu and clicking it again, without chosing a different entry, it isn't closed (as I'd expect) - at least not always. Sometimes it works. Might be my windows installation? (I feel somewhat inadequate, posting minor UI annoyances instead of actual problems that hinder the print process...)
  23. A checkbox would be least ambigous, therefore preferable. Although normally I'd assume that a search option within a thread only applies there. But I am mostly used to phpBB style forums, so that may be just me.
  24. This probably isn't really a Cura problem, but rather user error or firmware "feature". But I hope someone can enlighten me because it's quite annoying and I'm in a foul mood already (not because of this, but once in a bad mood, everything will make it worse :-/ ) Here's the situation: I want to print an item. As usual, the head goes to 0/0/0, lifts a bit, extrudes filament. Now it usually goes straight into the middle to print, but sometimes (as in, some models, not all of them - but it must be in the GCode, it's consistent) the head is lowered again, and it moves very close (I think at printing height) across the bed, dragging the pile of extruded filament with it. What it usually does is go to the middle, lowering the head while doing so, thus NOT dipping into the discarded pile of filament. Did I spoil the settings somewhere? I'm quite certain it doesn't always do that. Though I don't keep book about the things it does... Cura: 15.04.3 Printer: Wanhao Duplicator i3 Windows 7
  25. Is it possible to add a way to search within a thread? I like to search within a long thread before posting something, but I don't like to click through 49 pages to check every page. (As I would have to do in this thread, to see if someone already asked for this.)
