Ultimaker 2+ extrusion kit on early Ultimaker 2 models.

Recommended Posts

Posted (edited) · Ultimaker 2+ extrusion kit on early Ultimaker 2 models.

Hi all.

I have tried to install the new Ultimaker 2+ kit for my Ultimaker 2, and have a few issues that I bumped into.

1. The Hot End Fan was not connected to the middle connector of the main board, but on the 4 pin serial connector pin 1 and 2. Do I use the center plug or the serial plug after the upgrade? It seems that the fan has the same speed on both connectors. What do I use?


2. No Ferrite core on the motor cables. My version did not have these. Will it be better if I had?

3. There was a statement on this in the installation manual that helped me that had the old board. Note: If you have an older model of the main board on your Ultimaker, you need to loosen the screws instead of pressing to remove the wires. Kudos to the installation guide.

4. The X axis limit switch was not the same as Y axis limit switch. The long lip on the switch has a funny bend on this one, but not on the Y axis. Are the switches supposed to be the same? I have problems that the head will not press the limit switch all the times due to its bend and it will not click all the times. I may try to make the holes for the alignment screws 1 - 2 mm wider.

Is it only my printer that has these experiences with the new upgrade kit?

    1. Use the connector in the middle of the board.

    2. Mine doesn't have the Ferrite core as well. I'm not sure how much it help but it will work without it.

    3. yep, that's white manuals are for.

    4. The bend on the switch is normal. Sometimes this needs to be bent to make sure the head is in the middle of the print area. Sometimes the head will hit one side of the machine, so you bend that tag to make it move away from the edge.

    The ferrite core is there to cut down on EMF from the printer. It's more to comply with regulation testing than anything. These were added to the UM2 quite late.

      • 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.
