UM2+ fanspeed setting


Recommended Posts

Posted · UM2+ fanspeed setting


Just bought a UM2+ and discharged the original.

I tried to find this here but no luck. I don't understand the fan speed settings.

I lowered the fan speed for ABS in the line of the Material.txt and imported it back into the printer, that worked.

Now if I'm printing the fans go right up to 100% again on the second layer and I have to change it manualy on the machine again.

So my questions:

Do I have to change the fan speed setting in Cura ?

And if so, what is that setting on the machine for?

    Hi Dree,

    You have to change the fan speed settings in CURA if you want to do it for the whole print. Another option is to use a plugin if you want to do this from a certain height or layer.

    I use an plugin called Tweak at Z, you can implement this in your CURA software.

    What you can do with this plugin, is changing the settings after a few layers.

    When printing ABS, i will recommend to use this plugin.

    You can now turn on the fan speed after a few mm (or layers), so you prevent your work from warping (print the first few layers/mm without cooling!).

    Thanks for the help.

    I see I have that plugin installed but I will try with the standard Cura settings first (advanced-cool) I do not yet have any warping issues with ABS (small prints)

    Edit, still want to now what that setting on the machine in your materials is for?

    The fan setting of the current material preset works as an (additional) multiplier.

    For example:

    If you define a fan speed of 50% in the slicer and use a material preset with a (max.) fan speed of 70%, your fans are actually running at 35% (0.5 * 0.7).

    With other words:

    The printer's "TUNE" menu always shows the value from the slicer (50% in this example), but the effective speed can be reduced by the selected material profile.

      • UltiMaker Cura 5.3 stable released
        In this stable release, Cura 5.3 achieves yet another huge leap forward in 3D printing thanks to material interlocking! As well as introducing an expanded recommended print settings menu and lots of print quality improvements. Not to mention, a whole bunch of new printer profiles for non-UltiMaker printers!

      • 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 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.
