  1. Yes. I think the support blocker is a good one because sometimes you do need it.
  2. Everything you describe would be done in python. So you don't need to modify CuraEngine. I strongly suspect you can also do this as a plugin which ideally should also be written in python. There are tutorials on writing plugins somewhere. I don't know much about it. This is too advanced for me.
  3. Cura is kind of dumb. It sees that top of the X and thinks it needs support. But it doesn't. Cura has lots of features to fix this. In the case of this exact issue, I'd use a feature called "support blockers". But put the blocker up near the top of the X - where the surface is that cura thinks needs support. Don't put the blocker where the support is that you want to take away. In PREPARE mode, click the model, then on the left there is a tool you click called "support blocker". Then click near the top of the X in your model. A cube will appear. Click the cube so only the cube is slected, then switch to the scale tool on the left side (second too from top?). Now scale the "blocking" cube to include the top surfaces of the X. You can select the move tool to move the cube around. You can rotate the cube. Etc. It's possible to load an STL to be the support blocker - you don't have to use a cube but it will do for your purposes. Slice again.
  4. If you will be doing hundreds of prints then yes probably print out an oiler. If you are doing one for now and have no plans for others for the next month then having to visit the printer for 30 seconds every hour is probably not a hardship.
  5. 1) Add a drop of oil to the filament before inserting into the bowden. Add another drop every meter (about every hour or so). 2) 10mm/sec print speed 3) Loosen feeder tension to minimum 4) Print at max recommended temperature 5) Is there any way you can print this on it's side? Or will that require support? 6) increase flow #1 is the most important and the one people are most hesitant to do. So unfortunately I have to explain it the most. It will not add holes into your print as some people expect. It will not harm your printer or the filament. It just works and it works very well. Of the 5 things above if you only do one, do #1. #6 - even at lowest tension, it will squish the filament such that the cross section is smaller. Which means less volume of filament is moving through the feeder than expected. I don't know how much less. Start with 10% extra (110% in the TUNE menu on the UM2). Maybe play with that until the layers are looking as good as the left image above. If you set this too high you risk the filament ending up in the feeder all curled up and making a mess in there. And that problem may take several minutes to appear as you are adding extra filament, then more, then more and slowly it builds up. You can do #6 only and skip #3 if you set the flow right. As 6 is basically compensating for #3 not being loose enough.
  6. @Ranshii - I think the feature you haven't noticed yet is that there is a PREVIEW mode to see the support and slicing results. This is a critical view to see if slicing is working properly. Never print anything without looking at the preview first. One way to get to it is on your 3rd screenshot there is a "preview" button. All your screenshots are in "PREPARE" mode. There are 3 "tab like" things you can click on near the top of the screen (PREPARE PREVIEW MONITOR). That's the more common way to switch to preview mode.
  7. As far as I can tell, both Ultimaker and fbrc8 have taken down the instructions which is a shame. However your reseller will have the instructions as a pdf. I've seen the instructions - very detailed. Lots of pictures. Call your reseller immediately or if for some reason you don't want to talk to them, you can contact Ultimaker. Phone/email support is free even if your warranty expired. Start by clicking the 9 dots in the tic-tac-toe grid in the upper right of this page. Then choose "support" and then the tricky part: click "submit a request" near the top of the page. That's the part that's hard to find.
  8. There's no need to guess. Ultimaker has very detailed and clear instructions. Let me go look...
  9. Wait, why do you want an algorithmic model? Can't your mathematical model create an STL file? If so then you could do this in python. Please explain a small amount about the mathematical model. For example if you want to warp the shape of an STL to a different shape, you don't need to change curaEngine.
  10. You will need to modify CuraEngine to do that. There are instructions somewhere. So you got compiler errors? Maybe repost the compiler errors but not in a zip file? @Dustin, is three really a pace in github to talk about how to build curaEngine? it seems github is just for bugs/features.
  11. @boyzkill are you trying to build Cura from source code (something only programmers should do)? Or are you just trying to install and run Cura?
  12. When the print order feature comes out, I'm curious if it only applies to "one at a time mode" or also "all at once mode". I'd wait for that before writing a plugin but if it only applies to "one at a time mode", then it sounds like you would have at least one customer for said script. 🙂
  13. We don't want her to get in trouble with the moderators, lol!
  14. I think it's "her". I'm pretty sure rachael and slashee are she/her. Can't you then output it all as a single STL? Would that not help? I guess you already thought of that. For me the "solution" issue is not so much that it doesn't work for "all at once" but that it's a workaround and only lets you choose the order if you want to print in one direction (left to right, right to left, front to back, back to front). And on top of that it doesn't help so much if you are printing a "grid" of objects as you can only say "row" order. Not part order. Still, it's pretty damn simple, easy to understand, and even has a visual reminder of which way it will print based on the shadows. It's a pretty cool hack. I think it could help a lot of people. Hopefully this will all be moot soon!
  15. I think it's pretty clear that it's not a proper solution and indeed it's useless for people in "all at once" mode. Also typically "all at once" mode you don't care what order it prints. But not always. I'm going to leave it at least for a few days. Hopefully 5.7 makes it all moot. Also don't think that this means Ultimaker is off the hook to add this feature. They are certainly still on the hook. And it looks like they already did it and it will be in the next release. I agree @rachael7 it could give people hope, only to dash it away again when they read it.
  16. I marked @jeroent as "the solution" even though obviously it's not the perfect solution - it is by far the best I've seen at this point. Hopefully it's all moot when the next cura comes out.
  17. Did you read this? It's the same interface since 2016: part1: https://community.ultimaker.com/topic/15574-inside-the-ultimaker-3-day-2-remote-access-part-1/ part2: https://community.ultimaker.com/topic/15604-inside-the-ultimaker-3-day-3-remote-access-part-2/
  18. Oh - and it's not the active leveling. Active leveling expects the right core to go down 1.5mm more than the left with a tolerance of 0.7mm. Beyond that and Active Leveling fails. It sounds like you are seeing errors of more than 0.7mm, lol.
  19. This is an S3? Can you show a video? It sounds like the collision isn't an end-of-travel in X or Y axis, right? The collision is only nozzle to glass? I guess I need to see it. I think I would try to do a factory reset - I think that might be in the menus somewhere. There are a TON of constants/values/parameters stored on the printer. For example, position of the print core switching device. Where to nozzle purge. How high to move up after a print. How much to extract after a print. Temperature values. And so on. One of those values is probably where to go in Z axis for the print core switch step (or how much to move the bed down). That value may be corrupt and may be negative slamming the nozzle into the bed. This is one possible theory (but it would be helpful to see what you mean in a 5 second video). One fix is to try "factory reset" if the S3 has that option (it might not - I forget). The other fix would be to try reinstalling the firmware. Again, assuming this is the issue. Also be aware that the "hard drive" (it's bascially an SSD) on the S3 gets corrupted somewhat easily and I know people who had to re-install the firmware because of this. Blocks of data just... fail occasionally. I'm talking like, on average, one block of data per month. 90% of the time it doesn't matter. But sometimes it corrupts something important - the block is automatically detected and walled off and never used again but it will read the wrong values until you re-install the firmware.
  20. I don't get those lines. I'm not sure why. I probably just print slower than most people? They aren't so obvious on white filament. I'm sure the UltiMaker Cura people will do it but it may take a year or two. Or someone not on the cura team will do it and do a pull request (PR) (this happens more often than you would think). Or someone will make a plugin. It's a pretty cool idea. It sounds like it's not a trivial feature and even though it works pretty well, there is still some tweaking to make it work in more situations. Reading what other people wrote, it's not a perfect fix. I'm not sure what the issue is but maybe certain geometry keeps it from working? Or maybe it only works in "spiralize" mode? Not sure.
  21. Well, I don't know if it's common, but it seems to me it's almost always the front fan. Look at the image, you don't have to take the print head apart, just unplug the fan as shown in the link. It could be that it's only 1% of people find out it's the front fan but I seem to hear from all of them, lol. So it seems like it's 80% of the issues but could be only 1% of the issues. I really don't know. Also this is a common issue when the printer gets worse slowly. Something about the fan gets worse slowly over many months/years.
  22. Yes, what Dustin said. Try everything they mention but a very common cause is the front fan. So try disconnecting it. If that's the issue it could be that this is fixed in a newer firmware - which firmware do you have? But also of course try the other things in that article. Keep running that sensor test and try to get it below 7 or 8.
  23. I wrote you a long answer and then realized that this article is much better: https://support.ultimaker.com/s/article/1667337565436 Cura does position objects in the center of the printable area by default. You can click on the object, select the move tool on the left and make sure that "x" offset is zero - that's the center. The origin is the left side so the center is not zero but the offset is zero.
  24. This is an exciting new technology for slicers. I only first heard of this last night and now it seems everyone is talking about it.
