  1. If you need plenty of cooling you can also take a look at the centrifugal fanduct by @gudo

    https://www.youmagine.com/designs/um2-centrifugal-fans-duct

    I have used it for 6 months and could not be happier...printed in PLA and no major issues with heat since the part closest to the nozzle is a piece of aluminium sheet from a can.

    You need to buy new fans though since it uses blower fans and not the ones that comes with the printer.

  2. Yes, that's my experience as well, just weird that the manufacturer recommends 195°C@0.1mm for strong prints...

    Well, imo, extrudr publishes very poor info/data on their filaments so i'm taking most if their info with a grain of salt. Which is a pity since at least Greentec is great...but without the info @neotko shared I would not have tried it, yet at least.

    At least they are very helpful when you talk to them directly. When they launched their TPU filaments recently I asked for data sheets so I could see what temp resistance they had etc. since there was almost no info available on their site. And I got the data, and more, from them in less than a day. Yet, as of today, there is no data publicly available on their site. And today they released yet another new filament...NX2...with little to no information available :/

  3. I have also used the same temps as @ultiarjan and I have not had any layer bonding issues.

    The only thing I have noticed with greentec is that the filament diameter on the spools I got is not so consistent and on at least one spool it exceeded the tolerance they stated. It is not as consistent as the ColorFabb filaments I have.

    But it still prints great :)

  4. I printed a bunch of stuff with Colorfabb XT sliced with S3D...and I just took my already tuned S3D profile for PLA and:

     

    • Cranked up the temperatures according to the tips&tricks page from Colorfabb
    • Turned down fan usage since I read that it was good to not use too much fan or you can have issues with layer adhesion

     

    That gave me pretty good prints...and I think I was printing at 50 mm/s :)

    The downsides I have seen with XT so far is:

     

    • It flows more easily than your average PLA so there will be more artefacts to remove...can probably be tuned better...I have since improved my PLA profile so I expect that I can improve the XT profile in the same way
    • It curls upwards on certain overhangs/corners and that seems to be the way this material behaves according to Colorfabb. On the other hand...the one time I really had an issue with it the overhangs were really extreme and I was surprised that the object was actually printable without support :p
    • And yeah...you can easily chip your glass...so try the suggested temperature change in the end gcode...on the other hand...this forced me to switch to regular glass on my bed and now my PLA prints sticks better to the glass than with the one included with the printer :)

     

    In total I think I have so far printed a spool of XT (bits and pieces in different colors) and I think it's a pretty good material. But given what is on the market now...compared to when I bought my spools...i'm not sure I would have bought XT.

  5.  

    I looked quick on ebay, its not called key steel, but just stainless square bar

    http://www.ebay.com/itm/STAINLESS-STEEL-SQUARE-BAR-ROD-10x10mm-8x8mm-6x6mm-4x4mm-3x3mm-in-many-Lengths-/122221236270?var=&hash=item1c74f4102e:m:mY31TxMyAuiiDbWodBcQuyg

    Its supplied in 400 and 500mm lengths in 4x4mm

    as long as its pretty straight, would it work ?

     

    Indeed that should work. @Gudo might now much better than me if that's ok or not.

    What I do know it's that you can 'rectify' them by hand, and love (always love ;))

     

    Don't expect them to be 100% straight...they are shipped in some bubble wrap and a plain taped envelope so even if they are straight when posted...you are at the mercy of the delivery service...I ordered 2 just to have one spare and hoping that 2 packed together would not bend as much as one...thinking that they would not be packed that well :p

    That said...mine were not that badly out of shape...tested them on the glass bed of our stove...maybe max 1 mm off on the whole length...and at least one of them I could straighten out pretty good with little effort...didn't try the second one yet

    But time will tell how good it actually works :)

  6. On the bright side the community (I mean the people) is great, this is probably why we are still around against all odds...

     

    True...and there is a lot of good stuff here...otherwise I would not come here so frequently...but you have to jump through hoops to find it :(

    Any News when the Bug with next page in sub forums gets adressed?

    This is really annoying.

     

    @sandervg

    Seriosly...this forum is, and has been for more than one week, unusable unless you want to read only the most recent posts :(If you can't keep your own software working maybe it's time to bite the bullet and use third-party software proven to work.

     

    Fast-forward almost 2 months and this is still not addressed... :(

  8. Have you looked at ApolloX?

    I have nothing but good experiences with that. It's tough as nails and resistant to just about everything under the sun. Including the sun. :)

     

    Could you please share some more details on your experinece with ApolloX? :)

    I just found out about this material and, as @purps wrote, it sounds too good to be true.

    I'm about to order a roll just for fun to play with. Although not listed on Formfuturas product page I guess you should have a well ventilated area when you are using ApolloX?

  9. I think i already mentioned that it was not in 2.4 ;)

     

    True, but you also said that it was changed two months ago...which is not true...since there is no Cura released with this function disabled by default...so this is not fixed yet ;)

    That said...i'm glad that Ultimaker finally came to your senses and realized that this was a very dangerous thing to have enabled by default :)

  10. The whole bed needs to be stabilized...it's really sensitive to vibrations. And the Cura 2.x release has made it even more pronounced since they appear to be "experimenting" a lot more with acceleration which leads to the head making rapid speed changes so it vibrates more.

    It is really obvious if you watch the bed when it is printing infill.
