  1. Ok I have a problem with Brim. I have an upside down cone shape to print, the top of the cone is just within the max build volume, the bottom is only 20mm diameter or something. My problem is I cant use the brim setting without having to shrink the model, which I dont want to do. Im assuming the brim setting adds the brim width to you models max dimensions. It should really add to the first layer max dimensions to avoid restricting build volume on models larger at the top than bottom. Is there anyway around this that anyone knows of?

     

    Thanks in advance for any input.

  2. Thats good to know about the ulti controller, thanks for the info. I guess its down to the heat directly transferring from the bed to the print rather than the whole chamber being that temperature?

     

    Looks like Ill have to find some 3rd party heated bed builds.

     

    thanks again.

  3. I recently bought a second hand UMO on ebay. Its not in great condition, belts are all stretched and it probably need stripping down cleaning and re-assembling. I don't mind doing this as is was quite cheap in the end.

     

    I still have the UMO I bought 5 or 6 years ago with a heated bed upgrade kit and the ulti controller both of which are no longer for sale as upgrades which is disappointing.

     

    So with that in mind I got to thinking about a heated bed chamber instead of a heated bed and here's where I'm hoping fellow makers can give me an opinion.

     

    Can a heated chamber replace a heated bed? If I heat the chamber to 60 degrees is that just as good or perhaps better than a 60 degree bed?

     

    Id like to use this machine for printing more exotic materials like PC, PP and nylon. I have had some success with my other UMO+ printing these materials by enclosing the chamber.

    Ill also be looking at replacing the hot end with one from E3d. Any opinions and advise welcome.

     

    P.S. Does anyone know where I can find a good set of instructions to make a 3rd party Ulti controller (or even better know anywhere that has stock)?

  4. Fellow ultimakers,

    Ok I might be missing something here but I cant figure out how to turn the fan off at a certain height in Cura. I know it can easily be turned on at a certain height or layer but I want to do the opposite. I'm printing some Colorfabb HT and the bigger layers are higher up (think inverse pyramid) so warping becomes an issue. I still need cooling on the lower layers though. I've done it manually and it prints nicely but Id love to be able to just leave it going knowing the fan will turn off. Any ideas?

    Thanks in advance for any suggestions.

  5. Yes indeed, I also have an UMO with HBK and I installed an E3D hot end.

    You definitely need the 24v version.

    I initially mounted it "as such", so it gets 19v. It works fine, even for high temperatures -- I printed PC at 280°C in this configuration -- but it is does not warm up as fast as with 24v. If you consider using the Volcano 19v is probably not enough.

    You can easily by-pass the 19v step down and use 24v directly, I recently posted an howto for that.

    Re the mount there are plenty available, I posted my own as well.

    Thanks for the info, very much appreciated! Ill check out your how to for the bypass.

  6. Fellow UMers,

    I'm considering upgrading my UMO with an E3D V6 hot end with the volcano pack so I can print hotter and faster with wider nozzles and other materials.

    I'm very confused as to what I actually need to order though.

    I upgraded my UMO with the heated bed and so it has a 24v PSU. SO I'm assuming I order the 24v E3d V6 version?

    Then I assume I need to print a mount for it.

    Is it this simple or am I missing something?

    Even though the PSU is 24V will the UMO board ouput 24V to the heater cartridge?

    Any advice very much welcome.

  7. Hello fellow UM'ers,

    I am trying to print a cut down spherical lampshade on my UM2 that measures 220mm (max dia) by 156mm high. For some reason Cura will only let me print it at 195mm dia. I checked the build volume settings in cura and they are the default size (larger than my object). I cant understand why Cura wont let me print at 220mm. Any suggestions welcome.

    Thanks in advance,

    J

  8. Hey fellow UM'ers just thought Id share this little tip. I had a few blockages with both my UM1 and UM2 in the past, I always wondered 'how is material getting into the nozzle to cause blockage?'

    So I took a small piece of sponge material, and pushed the filament through it before it goes into the extruder, then attached it to the extruder with a rubber band. This means it it cleans the filament as its pulled up into the extruder. No blockages since !

    I've had this little mod on both my UM1 and UM2 for 2 months now and done a fair bit of printing so I do think its working !

    (UM1 is for sale in the for sale section If anyones interested !)

  11. Hello fellow U.M.ers. I got my new UM2 this week after 2 years using the UM1 (which I still love!)

    One thing that's troubled me slightly is I don't have the option to change the temperature in CURA for my UM2.

    Can someone fill me in on :

    1. Why the temperature settings have gone ?

    2. How is the temperature determined If I'm not setting it ? (I really hope its doing something intuitive based on the rest of the settings and printing at the lowest sensible temperature !)

    3. Is there a way to set it manually If needed ?

    Thanks in advance for any insight into this !

     

  12. I had a question about my order for a spare part too. I got a reply saying that they had contacted the logistics department but didn't have my order number so couldn't get any information.

    The order number was in the title of the e-mail, including the one they sent back to me stating they didn't have the order number....

     

  13. Unfortunately you will have trouble getting it on a normal spool the inside diameter of a faberdashery spool is much larger than a standard spool your looking at about 10 -12 inches. it would just spring open that's if it did not snap trying to wrap it round a standard spool which is about 55mm diameter..

     

    I had a lot of trouble putting fabadashery filament on the ultimaker spools until I tried doing it on a broom handle(running through reel and spool centres), it takes a bit of time but it fits on there and the broom handle keeps it from tangling (it still kind of birds nests but If you gently spin it the opposite way your winding it on it goes back to a manageable reel).

     

  14. I hear you, I'm excited about predictions in lots of new SLS machine coming out now key patents are up but the build volumes of the current offerings un 5k are far too small for me. Maybe next year.....

    Its looking like a UM2 for me. Just need to sell the UM1 to part finance it (in the for sale section If anyone's interested)

    Ill be sad to see it go but I'm hoping there'll be a small step up in print quality and a bit less time spent maintaining and tinkering with the machine.

     

  15. I certainly prefer the ideals of Ultimaker, and I have been very happy with the UM1, the support I've received and the help and advise Ive had on these forums. But ultimately I want the best quality 3D prints possible within my budget. This is why I was so disappointed with the MAKE reviews this year, because all I have to go on is the sentence at the end of the UM2 review saying it has some catching up to do, which I'm not convinced is true. The build volume of the UM2 is probably going to be the clincher anyway.

     

  16. I bought the PDF of the magazine, as Id done the year before prior to buying the UM1. I have to say it didn't feel like as comprehensive review had been done this time round. I cant help but ask myself question like do Makerbot and Make magazine have a very good relationship now ? Is their marketing/branding team very good now major money is behind them. I'm not saying there was anything dodgy about the reviews but the cynic in me just wonders whether this could of had some sort of very small bearing on who pipped the other to the post ? As I say this is the cynical side of me, for all I know the Makerbot 2 really does print better than the Ultimaker 2, but there was nothing in that review that seemed to back up the results in any way. I am currently trying to decided between a Makerbot 2 and an Ultimaker 2, I dont feel like the review has really helped me decide.
