  1. Is there a good place to report lack of clarity to newbies issues? (And suggestions for improvement?) A really basic diagram of all the parts and names would be a good start.
  2. Thanks, I eventually figured out what it was talking about. It would have been nice if there were pictures or diagrams somewhere telling me what this bay looks like, I find the documentation pretty lacking for someone that's never had a 3d printer before. (And I did read the whole UM3 manual.)
  3. Are there more detailed instructions on how to calibrate the lift switch than what it says on the machine? What am I moving where?
  4. Yeah, but I'm way less intimidated by software than hardware. And I'd have to move my fancy cardboard box cover more...
  5. Thanks for the video, getting the part to stick right is definitely one of my biggest problems. And then sometimes when I think I have the best settings for a material figured out, the next time I use it, something will go wandering just to spite me... (I've done some prints of multiple nuts/bolts, and sometimes *just one* will start roaming around. And of course not the same one every time, so it's not a clear sign that one area has maybe a different temperature....) How would I find where the first layer starts and ends in the gcode? So the line I'd add is "M221 s200" (and later "M221 s100"
  6. Upon further inspection, I found issues similar to the ones in this thread: https://ultimaker.com/en/community/33658-um3-good-quality-but-poor-quality-control Cracks: This one is also finely cracked, with the crack going along the rod, but I couldn't get an angle that made the crack show up. (The smudge along the plastic around the motor is what I mentioned earlier, and there's also a crack in the case you can see at the bottom of the picture.) More clear on the grinding damage and other crack: On the other side, a scratch where the plastic covering pops in: And the LED wire ru
  7. It's the icon on the left near the bottom of the list. (Took me a while to find it, too.)
  8. Here are a couple pictures from the bottom with better lighting. The silicone when I got it looked basically like that (part of the edge tucked in, part of it out), but since the print heads also weren't symmetrical I figured that's how it was supposed to look. And speaking of how things are supposed to look, are there detailed pictures or diagrams of how everything is supposed to fit together? When I received the printer, one of the tabs for the plastic cover over the motors on the right was popped out of its slot and I didn't notice until my first print, when one of the arms holding up
  9. The silicone cover looked like that I think since I got the printer a month ago. (If not, it happened during the first print.) I'm pretty sure it was because the print detached, but maybe it detached because it somehow got stuck to the nozzle? It's done the pushing the print around the plate thing a couple times, usually I've caught it pretty quickly. I thought I was fine to print overnight because I already ran two prints of the same model and it was ok. (Well, one had some warping, but no sliding around the build plate.) I'll get in touch with my reseller, thanks.
  10. I started a print before bed, first couple layers looked fine, then I woke up in the middle of the night and saw the print head pushing around the whole print, cancelled it, went back to sleep. Here's what I was greeted with in the morning: The blob wouldn't budge, so I had the great idea to heat up the print heads to loosen it. I heated them up by 20 degrees until I could pull the plastic off (200 degrees finally). Then I had the great idea to open the fan shroud. It was stuck on from the plastic flood, I finally got it open a little and a little molten plastic came out and immediately
  11. With printing medical devices, is there any concern about lead contamination from the brass nozzle?
  12. How long is "quite a while" (for PVA or PLA)? I have some PLA that's been sitting out a couple weeks... oops.
  13. Is it possible to print a model with only the second extruder? I wanted to leave two different materials in the extruders, so I don't have to change the material between prints. I've gotten it to print the brim with the second extruder, but then it goes on to print the rest of the model with the first extruder. Using Cura 2.3.1
