Filament change does not work with my ultimaker s5 pro printer.

Posted · Filament change does not work with my ultimaker s5 pro printer.

I want to change filament during printing.
I used the "Filament Change" script.
The printer stops as expected, but the unloading of the filament did not take place.
I've tried unloading the filament manually on the S5's LCD, but it's impossible.
I suspect that it is the "Material station" which is not foreseen in the script "Filament Change"
I thank you in advance for your help.
I wish you beautiful impressions 🙂

    Without the MS it's easy.  Just lift the lever, slide out the current filament, slide in the new filament.


    I don't have a Material Station so I don't know if this is supported.  I guess 2 filaments (left and right core) are not enough?

    I agree with your answer. When you don't have station equipment, it's easy to change filament.

    With MS, when you have a problem with the filament, for example a filament breaking in a bowden tube, you have to remove the filament manually.
    To remove the broken filament, you have to turn off the printer (the MS too), lift the lever and manually pull the filament.
    You cannot remove the broken filament with an MS on. The MS motors do not allow manual removal.

    For my filament change problem:
    The script has successfully stopped the printer at the correct layer. On the other hand, when I want to remove the filament, the buttons on the LCD screen are grayed out.
    I did 2 tests: the first is the use of the "Filament Change" script with the Firmare checkbox checked.
    The second without checked firmware and with 2600 mm of retraction (MS->extruder filament length)

    Nothing running. No withdrawal made by the MS

    What I imagine to solve the problem (2 possible solutions): Make available the roll unload buttons on the LCD screen of the S5 when the printer is paused.
    Or modify the "Filament Change" script to handle the MS.

    Can anyone help me? another solution that works?

    In the top right corner of this page there are 9 dots in a grid.  Click that, select support, then in that same top row click "Submit a request" and put your request in there.  This is the best way to get a change made to the firmware.  All requests are looked at.  All of them.


    Unfortunately the firmware team seems to be behind their task list worse than any other engineering group at Ultimaker *and* I think there have been some layoffs in engineering in the past few weeks.  But this is a very valid, important feature to have (ability to change filament on a given layer in the print).  Just as important as "pause at layer" so you can insert an embedded nut or other hardware into the middle of your print.


    If you needed a change to the Cura code it would be easier but this is a firmware issue.


    If it were me, I would remove all the filaments, power down, disconnect the MS completely and operate the printer without the MS long enough to complete your needed prints.

      • 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.
