    Ultimaker 3 Bed not heating

    I'm also having this issue! I can't understand it. The profile is correct, Cura is in its latest version and it was even working fine before. Previously I printed with PLA and the warm bed was no problem. The pre-printing sequence went bed levelling -> print core heating -> bed heating -> print. Now it seems to be straight-up skipping the bed heating stage and just trying to print straight onto a completely cold bed! Edit: User error. Turns out there was a new Cura update last week and this seems to have solved the problem (and also tightened up a whole bunch of other little UM3 niggles like jerky video feeding, etc)

    This model was made by Thingiverse user DutchMogul for the Make-A-Thon design challenge and no wonder it won because it's a LOVELY design. No support needed for the lid and look at that bridging! Very sexy. The hinge is also fully functional and fits comfortably enough that I doubt it will break any time soon. I also love the raised dots and pattern. A little bit of elephant's foot on the rim of the lid meant that it didn't want to close at first, but some work with a pen knife sorted that out. Similarly, the key did not want to fit into the lock at first but a little bit of effort on the lock and the key with a needle file worked a treat. Printed at 0.2mm layer height at 195°C on the advice of a friend who suggested lowering the temperature a little bit for printing woodfill. It's also worth noting that this print took two attempts because a bit of crud in the woodfill completely blocked the core the first time round. Got to do my first cold-pull unclogging! Edit: Forgot to link the design! http://www.thingiverse.com/thing:548151

    My very first dual-colour print on the Ultimaker 3. I used some of our own PLA that I found propping up someone's monitor and it worked really nicely. The red is spoolWorks Phonebox Red and the black is spoolWorks Basic Black. The small layer height gave a lovely smooth effect but of course took bloody ages. The black parts are of a slightly lower quality than the red, and this is apparently because the black prefers to print at a slightly higher temperature. There is also a very small amount of nasty denting at the tip because i was a little rough when getting the print off the bed. And of course, most importantly, it works! Absolute pain in the arse to put together AND take apart.

    Printed with recommended settings in British Racing Green Edge on an Ultimaker 3, as practice/testing. The detail is lovely and the joints rotate freely, but the two halves don't quite join correctly. As you can see they're not flush against each other. Not sure what's caused this as the settings seem to be otherwise spot-on, with only very minor catching inside the joints and angel-hair in the body. Might just glue the two halves together
  5. This is actually a really interesting discussion re: the Olsson block, and it's created a lot of chat in the office this morning. I've gone back to engineering and have a clearer picture of things now. Olsson blocks, as you know, were basically made to adapt the UM2 for E3D's nozzles, and they achieve this by having the same thread-type as we use (M6). This means that in theory they should perfectly fit our nozzles, which is great and cool and means that we get to make nozzles for the Ultimaker community. But in practice the threaded section of the nozzles are longer than the Olsson block threaded hole, which can have some unfortunate consequences with regards to cooling of the nozzle from the print cooling fans - which can result in higher back-pressure and temperature oddities. The Olsson block is indeed an easier nozzle change due to the fixed block design. The main reason for changing out the hot end would be a drastic improvement in performance with the less common materials that do want higher temperatures. There's also some potential gains in longevity with the lack of TFM/PTFE in the system, particularly with abrasive materials. However that's postulation from engineering and not something we've tested. On the feeder side, as far as we can tell the UM2+ feeder runs a 2:1 gear reduction, slightly less than the Titan 3:1 - not much in it, but worth noting. The filament path is indeed much more constrained which should make the difficult job of pushing flexibles up a bowden tube that little bit easier. The largest factor in Titan vs UM2(+) feeders however is the drive gear. UM have used a standard diamond knurl as the drive surface in their feeders - this works, but in the UM2+ feeder it ends up being the limiting factor. Gearing is good, but if you don't have the grip to back it up it doesn't count for much. In Titan we're using a custom machined tooth profile that we spent a lot of time tweaking. It offers a decent grip improvement and also sheds filament debris more effectively than a knurl which can get all full of gunk. TLDR; This kit lets you hit higher temperatures, for the more adventurous materials and gets you a significantly upgraded feeder. It's not for everyone (not a kit-based noob-money grab!), but if you want to push the limits then it might be an attractive option.
  6. Sorry about the marketing bullshit So the reason we haven't got a comparison to an Olsson block on the table is because honestly I don't have the specs for it. I've just chatted to Sanjay and we'll try and get them and add them to the wiki hopefully on Monday, but I did want to link to the wiki since a number of people were asking what the point of the E3D upgrade even was. But you guys are all experienced makers and smart people and you know what can be done with UM2s. And you're absolutely right. UM2s can print a wide range of filaments including PLA, ABS, CPE, CPE+, PC, Nylon and TPU95A. It's just that the Titan extruder in the kit adds a LOT of pushing power which adds more than just the heating capabilities of the V6. Nonetheless I genuinely am sorry for any slick brandiness that might have come off in my OP. Wasn't my intention and I hope it hasn't pissed too many folks off, I really didn't expect this much of a response!
  7. Sorry about that LePaul, I'm just a new hire and trying to get used to the community and get excited about printing and so on. We use Ultimakers really regularly in-house and I'll hopefully get to keep playing with them and posting prints and experiences (not just 'marketing bullshit' )
  8. I realise that the video I posted doesn't really go into details re: benefits of upgrading, but all3dp have released an (impartial!) review that goes into a lot of detail about the pros and cons of the E3D upgrade, available here. In short, the benefits are: Better extrusion Swappable nozzles Heating to high temperatures (though I get that that isn't your bag) Print pretty much any filament Though if you're interested in just a raw spec comparison we've got one here.
  9. People have been modding their Ultimakers to make use of the E3D ecosystem for years, so we've released a kit that contains everything that the technical tinkerer or engineering aficionado could need to boost their Ultimaker 2. It's still quite an advanced project though, so we've teamed up with Tom Sanladerer to help guide you through 8) As ever, the documentation is up on our wiki, along with a comparison table for those wondering what the point of this mod even is.

    Printing PVA = Lots of problems...

    Scaffold is indeed PVA-based so warming your PVA on a bed should hopefully work for you. I also believe that Tom Sanladerer bakes his filament to dry it, which should work as long as the temperature is VERY low. It's genuinely quite a challenge to keep PVA dry enough to print reliably though (hence E3D's vacuum-sealing and desiccant), as moisture doesn't just mess up the filament melt, but also dissolves PVA and messes with its chemical structure.

    Here at E3D headquarters we get to play with a LOT of 3D printers. It's one of the perks of the job, but when we get a new printer we're still always very excited to see what it can do. When the Ultimaker3 came in we thought it deserved a more exciting stress test than old reliable benchy. Enter: These beautiful gems and their vertiginous overhangs. We printed in our own spoolWorks Edge filament in British Racing Green, which gave a beautiful metallic, semi-opaque satin finish.
