Just to clarify - there's no such thing as the "UM1". Because Ultimaker didn't want to imply that the UMO is older. Because the UMO gets updates all the time and is sometimes the newer printer and then sometimes the UM2 gets an update and then the UM2 is the newer printer for a few weeks. So it's "Ultimaker Original" and "Ultimaker2".

    Note that the builder3d-printers only use this to mix fillaments in a gradient. Quite different from dual material.

     

    This is not true, they use a prime tower when changing filaments, to get rid of the extra internal filament. I have seen them print with double colors and with pva. They showed several printers at the RapidPro (februari 2015) printing all day with different setups.

    I have been looking into mixing different filaments (high carbon with pla)

    I must admit I also bought it expecting there to be dual extrusion in the future.

    Yeah same here

    Is pva a ployvinyl...acetate?

    polyvinyl alcohol…

    The support from polymaker sounds interesting. But until there's a seller in europe I'll wait.

    Does this program do the following. : Estimate print time, material quantity and cost before printing.pp

    A few of the reasons why I went with two feed one nozzle,

    1.) same feed rate per line but double the production

    2.) exact same melt rate per line but double the production

    = no material slippage yet higher production out of a single "mouth"

    3.) with two feeds it will open the availability of tinkering with high carbon filament/PLA mixtures

    The original problem is the low cc/m that I was achieving out of 150 mm/s through a .4 nozzle

    so I bored out a .4 to a 1.6 (I could care less about ultra high accuracy in my line of work. this was perfect until the material melt rate couldn't keep up. So I knew I couldn't melt pla at more than 350C ish. So the solution was that I needed to be melting more than a few mm of material at a time. (enter Dual feed single "mouth"). Basically the general goal is print at aproximately 250-300 mm^3/s. Not too far off to imagine considering I was getting about 220 mm^3/s consistently (according to cura).

     

    I see you haven't been on here in awhile. I was wondering how your 2 into on was doing? Any pic's of it?

    Thanks Ed

    Shes doing fine. Unfortunately i dont work in the office for the company that owns the printer. Now i only consult for them.

    But they are still using the printer and it is working great.

    Hello everyone

    I'm new in the forum even though I follow you for quite some time, I have a UM2 + modified dual extruder and I've installed 16.12.1 Tinker, work Cura 2.4.0, when I start the print the machine stops to release some of the material before starting to print, stays for 3-5 seconds without releasing it and starts printing, is there a way to change the time of release of the material before it starts?

    thank you

    I think you have a wrong word in there somewhere. Could you try to rewrite the question? It doesn't make sense to me, sorry.

      • Here it is. The new UltiMaker S7
        The UltiMaker S7 is built on the success of the UltiMaker S5 and its design decisions were heavily based on feedback from customers.
         
         
        So what’s new?
        The obvious change is the S7’s height. It now includes an integrated Air Manager. This filters the exhaust air of every print and also improves build temperature stability. To further enclose the build chamber the S7 only has one magnetically latched door.
         
        The build stack has also been completely redesigned. A PEI-coated flexible steel build plate makes a big difference to productivity. Not only do you not need tools to pop a printed part off. But we also don’t recommend using or adhesion structures for UltiMaker materials (except PC, because...it’s PC). Along with that, 4 pins and 25 magnets make it easy to replace the flex plate perfectly – even with one hand.
         
        The re-engineered print head has an inductive sensor which reduces noise when probing the build plate. This effectively makes it much harder to not achieve a perfect first layer, improving overall print success. We also reversed the front fan direction (fewer plastic hairs, less maintenance), made the print core door magnets stronger, and add a sensor that helps avoid flooding.
         

         
        The UltiMaker S7 also includes quality of life improvements:
        Reliable bed tilt compensation (no more thumbscrews) 2.4 and 5 GHz Wi-Fi A 1080p camera (mounted higher for a better view) Compatibility with 280+ Marketplace materials Compatibility with S5 project files (no reslicing needed) And a whole lot more  
        Curious to see the S7 in action?
        We’re hosting a free tech demo on February 7.
        It will be live and you can ask any questions to our CTO, Miguel Calvo.

      • UltiMaker Cura 5.3.0-Alpha 🎄 Tree Support Spotlight 🎄
        Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm
         
        We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports.
