  1. Ok, I got an idea why. Thinking about some modifications.

  2. Problem solved! Carelessness strikes again. Turbocad is kind of finikey when it comes to making holes in or hollowing out objects. To make the hole or hollow by subtraction, the piece being subtracted must extend beyond the boundary of the piece that is to have the hole or be hollowed. In my case, I had a plug that I was subtracting from what would be the outer shell. I changed some dimensions on the outer shell but forgot to change the plug. So, I had a hollow shell with a layer, probably a small fraction of a mm thick, over the bottom of the hollow. I assume Cura was trying to read the result as a solid and getting confused. Finished routing out the opening on my drawing and it seems to be printing as planned.

  3. just to get a feeling for the scale, original UM2 vs Hemera, both without fans I've been looking at this as I would like one of my machines converted to direct drive for flexible materials. The hemera is to big for my taste, a pancake motor version would already be better. I'm also looking into a bondtech BMG + pancake + mosquito hotend, this looks a more interesting option imho.

  4. Another promising approach is this one (IMHO): https://www.instructables.com/id/3D-Filament-Fuser/

  5. I'm not sure why the authentication was removed from Connect. I've heard some vague reasons, but nothing concrete. The authentication is also very far from what most companies / large organisations would want. Just a simple authentication just isn't enough. You probably want some sort of role based access, preferably tied in to whatever is already in use (eg; Active directory, or something like that). But that's a whole lot harder to do. I know that we helped out some people in setting up a gateway that sits in between the printer & the network that does allow for authentication. I've already forwarded this topic to some people, so I hope they will contact everyone here that is interested about this.

  6. I don't really understand your reaction. You don't have a problem with the printer, you have a problem with the PVA material. Yes it absorbs quickly and a lot of moisture from the air, that is also the reason it should be stored in a dry place and for longer prints also during printing. Thats not the fault of Ultimaker, it is a property of the PVA material. It would be the same, if someone is printing PLA and then rant because PLA gets soft in a hot car. You should always store the PVA spool in an airtight bag or box, with some silica packs to keep it dry. And if you are in an area with high humidity, then you should buy a Polybox, whch keeps the spool dry during printing. Thousends of users are able to print successful with the UM3 and PVA, you just have to handle it in the right way.

  7. Man, it's confusing, fieldOfView on github is ahoeben here and burtoogle here is smartavionics on github. Who are these people? Anyway, thanks for the hint, I'll have a play with that tomorrow.
