    Matchless V3 E3D Nozzle

    in Improve your 3D prints

    Posted

    Hi!

     

    I've recently bought the Matchless V3 block for my Ultimaker 2 Go, but I'm having trouble with the nozzle not extruding properly, so I'm going to replace it. I was looking for a nozzle that could work, so I tried my Mk8 nozzle for the Anet A8, but the thread is too long. I can buy 1 brass Olsson nozzle for €20, but that's a little expensive imo. I was wondering if the E3D nozzles (or any other cheaper nozzle brand other than E3D) work in the Olsson block.

     

    Thanks for all the help!

    You can also use the 3DSolex Matchless block, which comes also with changeable nozzles.

    I took a look at what 3DSolex has to offer, and I think the Matchless heatblock is exactly what I need. They also have chrome coated brass nozzles, which is what I'm going to use for now.

    I also modified my um2go to use the 3dsolex heated bed upgrade kit.

    The heated bed is something I also want to upgrade to. I was wondering, what system upgrade did you use? The one provided by 3DSolex or a custom one?

    You can buy the original Olsson block at any ultimaker reseller, as it's a spare part for the UM2+.

    If you print a lot of abrasive material also have a look at a "ruby" nozzle iso stainless steel...

    Thanks, I will keep it in mind. For now I think a chrome nozzle is enough, since I will be printing 'galaxy' filament, which has metal foil mixed in to make it shine.

    And in addition: keep in mind that not only the nozzle will wear out but also the transportation wheel of the feeder (this doesn't take long if you use e.g. carbon filled filament).
    It depends on your use case, but (perhaps) consider a change to Bondtech feeder as well.

    How much does it wear out? I hope it will last a while since it is also made of SS and I'm only using foil filled filament, but I will keep it in mind when I start noticing grinding.

     

    Again, thanks for all you help! Have a nice day,

    UM2GO Nozzle

    Hi,

     

    I bought some filament which, unfortunately, is a little abrasive. I went searching online for a stainless steel nozzle with a bigger nozzle size for the Ultimaker 2 Go, but I found out the Olsson heat block is, as far as I've looked, permanently attached to the nozzle, without any way of getting it out (maybe drilling, but that doesn't seem like a good idea), and I couldn't find any brass heat blocks for sale.

    So I was wondering if you guys maybe know where I can find a replacement heat block/nozzle combination, and if possible a stainless steel nozzle instead of a brass one.

     

    Have a great day,

    UM 2 Go clicking

    in Improve your 3D prints

    Hi,

     

    I am new to Ultimaker printer, and I just got my hands on a lightly used Ultimaker 2 Go, which doesn't have any problems so far except one:

    When I try to feed it filament, it all goes fine until the step where it should slowly push filament through the nozzle until it comes out. When it comes to that step, the extruder stepper starts moving the filament forward for 0.5mm and clicks back 0.5mm. I've tried to readjust the feeder tension making it tighter and loosening it, but both don't do anything, except making the clicking slightly louder/quieter.


    I hope one of you what's going on and what I could do to fix it.

     

    Have a great day,

    My approach to teaching the 5th - 8th graders how to draw 3-D models also included learning how to code in JAVA. It turned out that using the free OpenJscad.com browser to teach 3-D drawing was a great introduction and preparation for learning more advanced work in JAVA.

    I am using Fusion 360 as a 3D modeling program. It is a technical program, as in it isn't good for drawing models of people for instance. You can download it for free using the Starter Licence.

    The printer that we purchased for the club was a JGAurora for under $300. Yes, this is not the best printer out there, but it is safe (everything is behind a metal case) and it prints reasonably well.

    We are currently trying to get the money for a Ultimaker 2 GO. It is a printer that is portable (we don't have a place to store it), it prints very well and we can show the kids what all the components do.

    Another free learning resource that I have successfully used is SoloLearn.com for very nicely done training in programming basics. They cover most of all the modern languages.

    I will definitely look into this! We make our own lessons with a uniform template across all the type of lessons we create, and we translate other tutorials from English to Dutch if necessary. I'm going to look into the lessons they have and if they are useful for the kids we teach.

    I wish you great success! It looks like you have an ample supply of mentors in your program. That is an area that I am having trouble finding support. Any suggestions would be welcomed.

    We got our mentors by advertising in local newspapers and contacting other clubs in the region if they had any mentors who would like to help at our club. I don't know if this is possible for you, but it helped us get a couple of volunteers.

    Hello all!

     

    I work as volunteer at CoderDojo in the Netherlands, Alphen aan den Rijn and we teach kids to program. I recently started teaching kids how to 3D Model, and they REALLY liked it! As most of you might know, 3D Modeling is fun, but it isn't as educational as printing the object in real life and learning from it's flaws. Since CoderDojo is a non-profit organisation, we don't get money from the CoderDojo Foundation but have to get it ourself. 

    That's why I made a GoFundMe page to get money for a nice 3D Printer. I very much hope posting it here would get some attentions so we can teach kids the fundamentals of 3D Printing. If you want to donate, you can do that here: https://www.gofundme.com/teaching-children-3d-print

    Your money could really help kids to get an understanding of how these technologies work!

     

    Thanks in advance,

    The CoderDojo Alphen aan den Rijn team!

    Anet A8 bad/inconsistant extrusion after changing nozzle

    in Improve your 3D prints

    Posted

    I just changed my nozzle on my Anet A8 after it was fully used up. When I started printing with my new 0.4mm nozzle (same as before) my extrusion was VERY bad and inconsistant, even so bad I couldn't continue printing because it would pull the first layer off.

     

    If I compare it to my extrusion before the nozzle switch, it is really bad, even though I tightened everything as before. I am quite sure it doesn't have to do with adhesion to the heated bed since I use tape with pva glue.

     

    Any advice on how to remove this under extrusion so I can continue printing?

     

    All the specs:

    • 25mm/s first layer print speed
    • 200C nozzle
    • 60C bed
    • PLA materia;
    • 0.4mm nozzle size

     

    Let me know if there is anything else you need to know.
