  1. Printer has been posted on eBay, if anyone is interested, please visit the eBay listing https://www.ebay.com/itm/283540932924
  2. Absolutely! I will play with your project and see if I can figure out which setting(s) fix the issue. Thanks.
  3. I have attached a minimal sample of the overhang issue. I sliced off the back section of the model (it should still be manifold). Overhang.3mf
  4. While that is definitely a solution (and I have done so in the past with Meshmixer before Cura added tree supports(, the fact that other slicers are able to provide support under the overhang leads me to believe that this is a bug (or configuration) issue in Cura and it would be great to solve this at the software level rather than modify the model.
  5. I did check them, I tried various settings (including 0.0 for each of them) with no apparent effect. The underneath side is red, it definitely thinks there is overhang here. I would have taken more images but I have no idea how to move the viewport in Cura with a touchpad (only rotate and zoom). This was created in Blender, but the normals as far as I can tell are correct (it should be manifold); and both S3D and Slic3r place supports under the overhang. Its not my model to post, but I should be able to cut off the part thats having issues and post a project file with that later this evening.
  6. I have a print with a relatively small 90 degree overhang. I have supports turned on, yet no supports are placed under this overhang. What settings do I need to adjust to get support under this? Other slicers (Like S3D and Slic3r) place supports here, but Cura does not. I have tried multiple printer profiles including the built in UM3 profile, and it does not generate support in this area. When I enable tree supports, it _does_ try and place some tiny half hearted supports here on the very outside edge, but that does not really support the rest of the overhang (and bridging here is not pretty)
  7. I am selling my Ultimaker 3, very good condition ~95 days printing. For $2500 + Shipping (US Only) It has the Bondtech DDG upgraded extruders (for both extruders) as well as the parts for the original extruders. Its in great condition with all original factory parts including 2x AA 0.4 and 1x BB 0.4 print cores. Here are some photos of the printer and a small sample of what I have printed with it: This is a print that I finished minutes before posting this topic:
  8. I have now listed it on eBay, so if anyone is interested, you can find it here: https://www.ebay.com/itm/Ultimaker-2-Great-condition-with-upgraded-Extruder-/283487859114
  9. Here are some more images of the printer in action, and some of the results:
  10. Most of the time I do, in fact I generally get many send report windows per-crash. Sometimes I don't though. I do not recall what the exact errors were. Generally speaking I get a lock up regularly when I drag/drop an STL file into the main window. I get an instant crash often (with half a dozen crash windows) when I switch between different printers (if there is a model loaded). The chances of these crashes occurring is increased dramatically if a model is being sliced when I do either of these actions. I haven't yet had either error occur when no model is loaded (but I haven't specifically tried)
  11. I worry about using plugins because Cura 4.0 crashes constantly for me as is. For example it crashed at least a dozen times yesterday. I don't want to muddy that (or possibly make it worse) by using unofficial add-ons. If the UI issues are known, and they are working on them, then I can console myself with the fact that it will be fixed at some point.
  12. I love how far Cura has come (it has replaced S3D for me as my go-to slicer). With that being said I find myself constantly frustrated at the new UI and think its a big step backward. If I had to point to the issue that is the biggest thorn in my side it would have to be the fact that the configuration pane is now layered over the 3d view, rather than actually taking up its own space. I hope that an option is added to adjust this or put it back to its previous behavior. For now I will likely stick with the previous version.
  13. Here are a couple of images from different angles as well as one showing the Bondtech DDG Extruder. These are thumbnails so you can click on each of them to bring up much larger versions. The black Bondtech DDG extruder is attached to the back (replacing the original extruder). I can include the original Extruder components as well for completeness. The orange spool holder is a 3d printed low friction spool holder (with bearings), and the original spool holder is there next to the printer. Here is a link to a video, I am afraid it doesn't show much, just the beginning of printing off a hollow Tree Top. https://drive.google.com/open?id=1njgGttQ5AI-v2e15lZkhfE42nvmgMWEr
  14. Later this evening I will, is there anything specific you would like to see?
  15. I am selling my Ultimaker 2+ for $1500 USD Its in great condition and has two aftermarket upgrades: A Bondtech Extruder, and a 3dSolex V3 Block. I will only ship to locations in the US. I can take pictures, or videos, if desired.
  16. I tried looking through the various repositories there, but I could not find any spool holder listed. The two that looked the most promising were the UM2 https://github.com/Ultimaker/Ultimaker2 and the UM2+ https://github.com/Ultimaker/Ultimaker2Plus repos, but I could not find any mention of the spool holder in either of them. Are you certain they are found on github? I assume they would be STEP files, rather than STL?
  17. I have been trying to find (with very little success) an STL file for the official UM2+ spool holder. Does such a file exist? I know there is one for the UM3 at https://www.youmagine.com/designs/ultimaker-3-spool-holder but I could not find anything for the UM2/UM2+
  18. Unless you have custom hardware modifications (like a new extruder with a different gearing ratio) then you should never have to adjust the extrusion multiplier greater than 1.0. I have found, 99% of the time, when you are not getting enough extrusion, its because you are printing at too low of a temperature. The walls not connecting is likely an artifact of this, the filament is coming out 'thinner' and not "squishing" enough. That being said, there is an "Outline Overlap" setting that you can adjust (mine is at 35% for my UM2+) that might help you here. Beware though that you might just be hiding another issue (like too low of a temperature). Also make sure that you have the filament size set correctly (you should generally do this every print, on any slicer, but at least once a roll).
  19. What you quoted was the user saying that they also experience this in Cura 2.4 (which was the original suggested solution). It does not say that he is currently using Cura 2.4 just that the recommended solution does not work.
  20. You assume that I have stayed on 2.5 (I was never on 2.4). I keep my Cura up to date. While Cura has gotten better, S3D still generates better GCode, has fewer issues and has many features that Cura lacks. I still use Cura when doing dual extrusion on the UM3 because S3D's dual extrusion is terrible, but for all else, I find that S3D always has a better print.
  21. If you are using a UM2+, my recommendation is to not use Cura. Use Simplify3D. If you are using a UM3, Cura seems to work fine (I cannot get S3D to work with the dual extrusion on the UM3)
  22. What I ended up doing was replacing the entire hot end with parts from thegr5store.com I bought these: ULTIMAKER2 HOT END HEATER 40W (SKU: HEATER40) TFN (HIGH TECH TEFLON) SPACER FOR UM2 OR UM2+ (SKU: TFN) TEMP SENSOR (SKU: temp-sens-um2) STEEL COUPLER V2 (SKU: steel-coupler) MATCHLESS NANO KIT (SKU: nano-kit) I also upgraded the extruder to a Bond Tech extruder. After these upgrades, it has worked perfectly ever since.
  23. I use the 0.4 nozzle, and as far as the print, there have been many over the last year or so. They are all parts that dozens of other people report perfect success with.
  24. I have been printing for awhile now, and I have never managed to get a "print in place" print to work correctly. What I mean is that any print that has movable parts that are intended to be printed as a single unit, never actually move. The parts are welded to each other. This happens no matter what slicer I use (Cura or S3D) and no matter what print material or brand I use. Additionally (and probably caused by the same issue), any time I print a part that should fit in another part (with small tolerances), it never fits. I understand that there is expansion and shrinkage in 3d printing, and the various reasons that the occurs, but clearly other people have managed to get these prints to work just fine. Any advice?
