    UM Original Controller Fan

    in Third party products & modifications

    Posted · Edited by Guest

    Played aroud a bit with a combination of 2 40x40mm low noise fans from PC modding and also similar sized blowers, but up to now I can´t find something silent with enough airflow and reliable.

    You can find a few attempts on Youmagine or Thingiverse but I fear (from my perspective), the one in is well greased the best of the bad...

    Is it possible to print One At a Time in Cura 2.3 ?

    in UltiMaker Cura

    Ok, so if my UMO is set up as dual extrusion, it is not possible to select "one at a time" as it always is related to the dual setup in my json...

     

    Correct

     

    Is there a way to select something like a "non" material on the second extruder or is the only workaround to add an additional printer with only one extruder...?

     

    Not at the moment. We are planning to enable the possibility for one at a time dual at some point, but it proved to be a tricky issue to tackle and had to make tough choices at some point. One at a time dual was one of the victims.

    A work around is to change the machine definition files (If only one extruder is used, it should work perfectly, but the setting visibility has no notion of what extruders are actually used at the moment)

     

    Thanks for clarification! so I will add an additional printer...

    b.t.w. what about reactivating the "change extruder" post processing plugin ?

    How is it possible to select the second extruder as e.g. it is loaded with a different colored material to perform a "one at a time" print with it before unloading the first extruder...? (often do this as my first extruder is always loaded with black PLA)

    I know, many questions, but maybe @nallath could give a hint?

    Start and End script

    I don't know. The dual extrusion script never got a whole lot of love from us (I have to admit i'd be hard pressed to find a working UMO dual extrusion in the office)

     

    Come over and I show you :-) (ok, not perfect, but working... more or less...)

    50W heater cartridge - experience?

    in Third party products & modifications

    Posted

    I have a 50w heater in my UM2go olsson block. It works great on every nozzle. You can print just as fast with 35w but 50w heats up faster from cold. I just wanted faster heat up times because of how the 2go heat bed setup works.

    You just need to tune the pid settings which is best done with tinkergnome firmware but you can also do it in pronterface.

     

    Where have you bought the 50W heater?

    Great insight - thanks!

    Now, upgradeability discussions are basically stopped I guess :-)

    Nevertheless, more Infos about the print core would be great. How is it built, how is the nozzle shape inside, comparison between AA and BB and the UMO /UM2 /Olsonn nozzle designs, dimensions,... and so on...

    Maybe next time?? :-)

    Ultimaker 3 upgrade kit

    in UltiMaker 3D printers

    Posted · Edited by Guest

    Sorry guys, I think there will be no sensefull outcome of this discussion (and a few other discussions in the forum) any more...

    I just will add now my two cents to get my frustration out of my mind, and then will stop thinking about (hopefully)...

    Sure, parts can be sources somewhere around the world, hacked together by somebody with 2 cents hourly rate and - of couse far below 12 years old...

    Nevertheless, something called "inventive work" has also it´s right and know how is expensive - and those who don´t have it pay for it... that´s the world guys...

    So I try to put simple: the guys from Ultimaker had the effort of development, putting hours of their employees into something inventive - and of course, they need to get paied for it...

    and then, of course every bit and byte - and spare part - need to have a price tag PLUS some overhead cost which enables them to go forward and pay their bills and develop something new on top...

    Honestly - buy cheap stuff somewhere in China or elsewhere - best something your local metal workers, farmers or textile manufactors or - better - the company you work for is producing. At least you will loose your jobs as nobody will buy something "expensive" from you and your company has to close down...

    And this is the reason why the prices from UM are ok... because they have the KNOW HOW and the ABILITY and the WILL to engineer their great stuff in The Netherlands (and hopefully pay their guys very good as earn it...)...

    So finally, I also think that a UM3 upgrade kit would cost a lot and need a lot of effort to implement it correctly (CE certified, safe, monkeyproof) and that´s the reason why it´s simply not feasible or sensefull - at least from a business point of view...

    So, now my mind is free of frustration - thanks for reading and hopefully I ignited the plug at somebody re-thinking his opinion...

    Questions about Ultimaker 3

    in UltiMaker 3D printers

    Wow, thanks guys for the fast reply. Playing with Cura 2.3 I get a build area of 171 x 171 mm when using two materials and 191 x 191 mm when using only one (btw how to select "none" for print core 2?). How can I achieve the advertised build area of 215 x 215 mm?

     

    That 35mm difference is the spacing between the nozzles.

    As to actually filling the advertised build area? You can't, just as on the Ultimaker 2.

     

    Aahhh... 35mm - so a little bit more than the space at UMO or UM2. So assume the whole head is also bigger... Thanks for the hint.
