  1. I had my Computer Aided Design students do the Starter Round yesterday. I think the framework is great. Ambiguous enough to get them thinking outside the box, but constrained enough to develop some focus on the idea. The class had a ton of fun doing it, looking forward to getting my hands on the full game. Here are some pictures and videos of my students working with it. This was just our first run through, I am looking forward to seeing the full game.
  2. I have a 2 Go and at the time went with a Titan extruder, Olsson Block, and a Print in Z build plate. I strongly recommend going with SOME kind of upgraded extruder. The stock one is just not reliable in my experience, the Medusa one on the GR5 store looks great and is nice and low cost. 2 to 1 ratio is nice. The Titan gives you 3 to 1, but its not like you would REALLY need that. I have no Bondtech experience to speak of but I do know they offer lots of filament control and as someone earlier mentioned zero issues with their prints. I will say that the Titan has had no problems once I got it set up properly for the filament. I assume the same of the Medusa since it's essentially a + Extruder clone. Whatever extruder you do end up with you will need to go to the Tinkergnome firmware which is really easy to work with. You need to change the steps on the extruder so it will work properly. As for Olsson block and V3 blocks. I run the Olsson and really like it. The V3 has multiple improvements to it, but I personally can't see them being a great bang for your buck. Someone mentioned a 35W heater. I know that GR5 sells them and I really like heated beds on printers, but I will say from my experiences for the last two years printing on a Print in Z build plate almost daily it's been super reliable, parts stick very well (PLA) but I have never run anything but PLA on that machine. If with these upgrades you want to run other materials, you may consider a heated bed. For what it's worth, I plan on picking up another 2 Go and doing the same modifications to it. Not only because then I have the same things to upkeep, but I know they work well. Also I have not yet done the TFM upgrade but that is next on my list of things to do. Links to the other mentioned things were provided but here is the Print in Z plate if you are interested in taking a look at that too. http://www.printinz.com/printinz-3d-printer-plates/
  3. Would there be more involvement if it were a Slack Group?
  4. Are there issues you're having? The only extruder I have upgraded on our Ultimakers is on the 2Go and that uses the old extruder design so it was a must. Our 2+ and 3 have no problems in our usage.
  5. Very cool way to make manipulative objects for student learning.
  6. Hello, I would suggest looking at the Ultimaker Pioneer site, I am one of the Pioneers this year and we publish content that may be of some help to you. What kinds of things are you trying to get students engaged with? This idea is great, but it is quite expansive. Do you have any specific targets in mind, do you have a software you want them to use?
  7. Yup... I doubt the setup can do anything other than what was shown in the video. Sure some people might find use of it but more likely it would be purchased, get used once or twice, and sit on a shelf. There are far more capable thermoformers out there for reasonable pricing or DIY setups.
  8. I'll try to keep as much of the build size as possible, for now it looks like I might loose a bit in X and gain a bit in Z. My main intent is to be able to get the CORE quality in terms of usable temperature range to the UM2, but the easy swapping is ofc also nice. Be aware it comes with a cost, pricewise nothing beats changing a nozzle on an olsonblock. Any thoughts on implementing a flex drive with it?
  9. The core problem was mechanical. And there was no easy fix we concluded after a lot of research. So releasing that has no real use other then wasting time. Electrically it was based on the AS5048B chip. So if you get out your soldering iron, you could still build this. Cables are still in place. Was the design integrated in anything or was it intended to be be a standalone component in the system?
  10. Is it possible to release the work that was done so that the community may pick it up?
  11. Awesome work! How much larger is this compared to the factory 2+ head? I assume the intent is to make an easier to swap nozzle that is better designed?
  12. Here is a resource that may help you dial in issues. https://www.simplify3d.com/support/print-quality-troubleshooting/#blobs-and-zits Your temp might be a little low and you are trying to compensate in other areas that may effect print quality even more negatively... I would start with doing a smaller test print and start dialing in your printer settings. Have you done any small print testing like https://www.youmagine.com/designs/hollower-calibration-pyramid to try different settings?
  13. I have not done machining on the UM Nylon printed parts, but why not use heat set inserts or embed fasteners and overprint them?
  14. Poly Carbonate and .8 nozzle would make me a very happy person. I imagine you are looking to release an advanced printer kit, door, etc. before or around the same time as your Poly Carbonate profiles come out?
