BondTech extruder and ultimaker 2 extended

Recommended Posts

Posted · BondTech extruder and ultimaker 2 extended

I have installed a bondtech QR extruder to my ultimaker 2 extended. I have updated the firmware to the bondtech firmware and have then factory reset the machine as instructed but the filament is only being pushed half way through when it restarts and asks to insert the material. It seems that the speed or esteps are only at 50%. Has anyone had any issues with this set up? Or have any advice as to what I can do to fix it. I think I can amend the esteps but it says I shouldn't have to do that so why would it be happening?

    Yes you have to adjust the steps/mm - there are instructions at the bondtech website.  There is a tool that does it for you or you can ssh into the printer and do it manually.  Both methods are explained by bondtech.  If you upgrade the firmware on the UM3 you will have to redo the steps/mm adjustment.

    pronterface won't control the UM3.  It has 2 computers.  the one that stores the steps/mm isn't connected to the external USB connector.


    The second computer in the UM3 is a linux computer and that computer decides the steps/mm and then sends the correct gcode on to the Marlin/arduino based computer.


    Anyway here is the instructions to change steps/mm:

      • 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.
