  1. I use my UMO+ daily and last year I installed a clone UM2+ printhead assembly, but I replaced the nozzle and coupler with OEM ones after several months of use. I also recently installed a clone UM2+ feeder/extruder assembly using the existing extruder motor and this has been working well. It is much quieter, especially during retractions. The BondTech, as @amedee mentioned, is a good choice, but for my purposes, a $12USD clone feeder was a no-brainer. You can also change to the GT2 belts and pulleys for a little more dimensional precision (less backlash). I did this quite a while ago.
  2. The issue is not how you are exporting the model. Tinkergnome has the answer to your problem in his post above. In Fusion 360, edit your thread features to be "Modeled" as he shows in the image. Otherwise they are just a visual representation of threads and they won't export in the .stl file. Once the modeled threads are created, they should export and show up in Cura or other slicer.
  3. @Torgeir and anyone else who might be interested: Since the printhead fan duct seems to have disappeared from the internet, I went ahead and designed a new one based on the gcode file you posted, but with a few modifications. It uses the existing screws to attach the fan, and it is captured on the printhead with the existing parts. I offset it downward a bit to allow room for routing the wires. I'm using it on my UMO+ with a UM2+ printhead currently. It's the yellow part in the CAD drawing below. It can be found at these sites: https://www.youmagine.com/designs/ultimaker-2-2-printhead-fan-duct https://www.thingiverse.com/thing:5244668 Thanks for the idea. I hope it's useful to someone.
  4. Will frbc8 ship to your location? https://fbrc8.com/collections/ultimaker-original-spare-parts-1 Otherwise, as @ahoeben mentioned, you can check aliexpress for individual (non-OEM) parts.
  5. @Torgeir Is this the fan spacer you mentioned? It seems like it would do what you describe. https://www.youmagine.com/designs/ultimaker-2-extruder-fan-mod
  6. In the US, you can also find silicone grease in the plumbing department of hardware stores for very cheap. It's used to lubricate the moving parts of faucets and things like that. As @geert_2 mentioned, make sure it's 100% silicone, which it usually is for plumbing, since it needs to be non-toxic for use in water lines.
  7. @coofercat Where did you get the spring-loaded feet design? That's something my UMO+ workhorse could use.
  8. Creating the mounting tab would definitely have been a lot easier in Fusion 360, since as @johnse mentioned, you could draw the profile of the tab and extrude it in one go. I have limited experience with TinkerCAD, so I thought I'd give it a try and go step by step so that a complete newbie might be able to do it. I hope it helps. @kmanstudios that's how TinkerCAD works...lots of booleans.
  9. Here's one way you could do it in TinkerCAD. The attached images apply to each step. Upload the .stl file you want to modify into TinkerCAD, then Add a cylinder next to the part and size it as necessary Add a box as shown and resize it Shift-select the cylinder and box and group them Add two cylinder holes as shown Shift-select the cylinders and the previous shape and group them to create the tab Add a cylinder hole for the mounting hole Group the hole and the tab to complete the mounting tab I hope that helps. Once you get comfortable using TinkerCAD, you should consider graduating to Fusion 360. It has a lot more capabilities. I would avoid using Sketchup because it tends to create non-watertight meshes that will cause trouble in slicing for printing.
  10. I don't know why exactly Cura is acting the way it is, but that for sure is a HUGE file. Have you thought about decimating it using a tool such as MeshLab? You probably wouldn't notice any detail loss, but you could significantly reduce the file size allowing Cura and your computer to handle it better.
  11. Is there a reason you can't export the model with support from Meshmixer as one STL file and then import that into Cura? I would think they would be aligned for sure then. Do you have "Automatically drop models to the build plate" turned off in Cura's preferences? If it's turned on, it could be inadvertently shifting your models' positions. The striping usually means that the object is too large for your printer's build area or it is located out of the build area.
  12. See this link: https://ultimaker.com/resellers/us There are no authorized resellers in the Bay Area that I know of. The closest would be MatterHackers in SoCal, otherwise there is 3DV Corp. in Portland.
  13. Yes you can. I can connect with my Win10 laptop, but typically I use an old version of Cura (15.04.6) because I like its bed leveling better than newer versions. I was also able to update the firmware using that.
  14. This looks like classic under-extrusion. What printer model to you have? Make sure your feeder is not slipping and do a cold-pull to clear the hotend if necessary. Search "underextrusion" for more ideas.
  15. The link you posted looks exactly like what my UMO+ has in the hotend. Also, you may want to try the printable belt tensioners if you continue to have problems with the belts skipping teeth. And the newer UMOs (including UMO+s) have the UltiController added on, which allows you to print from an SD card. A cheaper option could be the RepRap Discount Full Graphics Controller.
