Wiring for dual extruders


Recommended Posts

Posted · Wiring for dual extruders

I have just completed the build of an Ultimaker, with dual extruders..

I hit a problem when trying to do the 'run first wizard' checks through Cura. End result, after kind advice from this site, I removed the second plug for the extruder from the control board, and at least got basic checks completed ok.

Upon troubleshooting the second head problem, I have noticed what appears to be an irregularity in the 'head' to control board wiring loom.

Looking at the underside of the machine, the extruder plugs can be seen; In pictures within building manuals, the wires are, from the right side of the machine, coloured; (temp1 plug) Yellow, Red, Black. (temp2 plug) Green, Orange, Brown.

However.... the wiring loom that I received, the Orange and Brown on temp2 plug are the other way round. Thus, I have (temp1 plug) Yellow, Red, Black. (temp2 plug) Green, BROWN, ORANGE. Tracing back from the head amplifier pcb's, it would seem as if Orange and Brown ARE the wrong way round.

I do not wish to just go ahead and swap these around in case I cause myself further problems...! Also nullify any warranty... Not having access to circuit diagrams etc, I do not know if this is right or wrong..

Can someone please comment...

    Hello als,

    i confirm your brown and orange appear to be swapped, my order is green-orange-brown on temp 2.

    On the plug that goes on the print head my wires are also green-orange-brown.

    So as long as yours are parallel, you should be fine.

    Does that help you?

    Hi Burki,

    Thank you for kind response.. Yes, and no.. :???:.. You confirm my suspicions. Thinking about it, I feel I must get this info confirmed by Ultimaker.. It is possible there are different versions of controller board or amp that have different pin outs or other ;

    Highly unlikely, I know, but if I make changes that are wrong, or damage has already been caused, the recovery bill will be on me !.. I am STILL waiting for Bowden tube, missing in the original kit shipment, and wouldn't you know, the head that's down is the one that I fitted the one tube I did get; I laced it rather than use the supplied spiral wrap, feeling it provides infinitely more support for this type of application..

    Must admit to being a tad disappointed at the mix ups, and delays.. I guess we are all human though.. I will get started one day.... Will try to get answers from Ultimaker again.. Thanks for your help.. Regards..

      • 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.
