  1. Oh thanks, I checked with 0,15 mm first layer, obviously not precise enough. Fixed and uploaded.
  2. STL files are here You need to print the fan bracket twice, obviously. As mentioned above, the housing part needs support. I used standard settings and 0.15 mm layer. And for support set overhang angle to 90 and touching buildplate only. The fan brackets will bend as long as there's no fan inserted. Thus they can easily be put into place. The four screws that are holding the bottom housing might interfere with the fans when folding up. I did cut them a little but you could also print tiny shims.
  3. The housing will print well in original orientation or upside down but needs a little support in both cases. The fan holding brackets are simple 5 min prints. As for the material, original parts are some kind of ABS, I suppose. So, UM already made sure to not expose it do direct heat from the print cores. Therefore any material which withstands at least 80°C permanently (or 100°C if you heat the print bed to maximum temp) should be fine. I used greentec pro.
  4. Hey guys, long time no see here. First of all, I'm happy that the Mark2 community is still alive (and kudos to @tinkergnome for doing the support work!) So, here's a small project which addresses one of the weaknesses of the S5 design: Prints which require good cooling, particularly with PLA and/or of smaller size, are really not among its specialties ... Printing with core1 shows even worse results than with core2 and walls facing left generally suffer more. There are two main reasons for this. First, introducing radial fans with the UM3 was a good idea but their positioning was - at least in part - driven by design criteria instead of functionality aspects. Air doesn't come straight out of these fans but more like in a 45° angle. As both fans are sitting behind the nozzles, this is a good thing for the right one, which blows to the front, whereas the left fan mainly blows backwards to nirwana. Second, there's only minimum clearance underneath the print head. Air cannot reach the nozzle tips directly but has to be diverted, which creates back pressure and reduces air flow. As UM hardware designers still freak out when they make optimum use of space, I suppose 😜, there's literally no space left to change the setup. Like only 1-2 mm to the side walls during homing or nozzle switching. But I wanted these fans to throw more air to the place where it's needed. After two days of brain racking, I thought the design should make use of another dimension: time. The head has to change shape. fans are folding in and out left fan flipped upside down to direct the airflow to the front almost directly pointing to the nozzles replaces the bottom housing of the original head printing time (3 parts): 3 hrs time to mount: 15 min Part files will follow very soon. Stay tuned 🙂
  5. So now it's: @Nomo @gr5 @Scrat82 @deisengard (3 units) Almost a reasonable number. However due to holiday season here the new estimated shipping would be late August.
  6. With "gets stuck" do you mean the filament can't be moved anymore or the filament keeps moving but the sensor gear doesn't turn (sensor wheels slipping)?
  7. But to me this looks pretty ok. Sensor wheel turns as long as the filament moves. However there some moments when I hear the feeder turning (I think) but nothing moves.
  8. PM with shipping address so far: @Nomo @gr5 (new) Other guys, come on! I need a little more feedback to place the parts order.
  9. @danyetman, @planeflake, @Ramzes777, @Scrat82, @reprogue, @Nomo Some news: Estimated shipping: early June Price, including shipping: € 75 / US$ 88 Shippping: tracked DHL shipping Please send a PM with your contact details.
  10. orders currently: @danyetman @planeflake @Ramzes777 @Scrat82 (3 items) @reprogue @Nomo
  11. Hey guys, Thanks for collecting orders 👍 I'll see how long manufacturing a next batch will take and keep you posted.
  12. I've one kit available at the moment. First come first serve 😉 Manufacturing a new batch would require at least 5 binding orders. And no, no news about a UM3 integration unfortunately.
