  1. Hi @gr5, Thanks for your reply. Having Cura 2.3 it seems to be inpossible to add ("tell Cura" as you wrote) another Nozzle Diameter. See my Screenshot
  2. Hi Sander, Because you are an Ultimaker team member I would really like to here from you if you know one or more sources of knowledge concerning the new 0.15mm Nozzle which is now available (e.g. how to set or instal this Nozzle dimension in the UM2+?). Or must I create a profile, derived from 0.25 and configure the parameters ~proportionally to 0,15mm? I would like to do tests with this 0.15mm for very tiny (with demanding dimensional tolerances) parts for real technical use in, say shaver sized appliances. Thanks in advance for your appreciated reply!!! John
  3. Hello to the ones reading this, Contrary to the opinion of quite a few people, working with profiles can be very useful if you often change material or nozzle size. But...Have you ever and over and over tried to create profiles and it did not work so well? Here are some reasons and solutions MAIN REASON: You attempted to do this from the Main Menu with either: A: Main Menu, Settings->Profile->Manage Profile, or B: Main Menu, Preferences->Configure Cura...->Profile While having a model in Cura. Then, in the Preferences Window maybe you selected a Profile and choose to ("Uuhhhh, does this mean Copy? I think so...") it with another Name ("Than I can edit and save that copy, is it not?"). UNFORTUNATELY that is not possible!!! Sorry man!!!!!! After you renamed the duplicated Profile in the "Duplicate Profile" Window and clicked the [Ok] Button there appeared no Custom profile. So the result was nil, null, nothing, zero, just as it was with me. What I discovered after a lot of trial and error was that there is only one good way to create your own Profile. SOLUTION.(One of the?) Create profiles without a model in Cura! Navigate to the the right pane of Cura and select in the Nozzle & Material droplists the desired values for your Profile to create, these values are the first input conditions for that Profile!!! Then select a profile matching with these inputs. You will see some parameters change according to that profile. Unfold the Profile droplist and see that "Create...", "Update..." and "Discard..." are disabled. Ok, now leave that list, change some value in "Print Setup" and see a star appear in the droplist. This means that the current setting is no longer according to the current Profile. Unfold the Profile droplist again and see that "Create...", "Update..." and "Discard..." are now enabled. Click "Create profile from current settings" and create it with your own custom profile name which will appear in the Custom Profile list. After more editing of the profile in the right Pane you can "Update Profile with current settings" REMARK: Having many profiles is not superfluous but very handy, especially if your own grey "Print Setup" memory is a bit fuzzy..... ("What were my best working settings for that Filament, four months ago?"). Hoping its useful for some of you, it was for me!!! Succes.
  4. Hello, "Avoid printed parts" is NO solution against rumble! This is only ment to avoid other parts when there are more parts on the build plate. The "avoid..." action is a "Z hop" if neccecary during x-y movement from one to another part.
  5. Hello, When I print Polymax (sort of HQ PLA) I have no problems (even with Nozzle 0.25, layer thickness 0.04, 100% infill), but when printing Innofil PLA with the same settings I also get that rumbling of the buildplate, as if the Filament does not flow out enough... and on top it shows like (micro) Emmenthaler cheese. Maybe (I will try) reducing the flow or the 100% infill? or temp? Also U 2+ Cura 2.3.0 Searching for other solutions...
  6. Is the following behavior of the Ultimate software (firmware) a Bug or my fault? I had an sd-card in my Ultimate 2+, which was printing from this card. My UM is, by usb, connected to my computer which was not running. By starting my computer the running UM restarted, interrupting and thereby ruining my print (the print process could not be resumed so I could throw away 5 hours printing). This turned out to be a structural behavior of my Computer- UM combination. Can anyone explain this or suggest a workaround? (Other than disconnecting the UM before starting a print?) PS This turned out to be a structural behavior of my Computer- UM combination after restarting COMPUTER AND CURA
  7. Hi, I have an issue with Cura 2.1.99 After doing some try-and-error sessions with Polymax PLA I found good settings for my specific needs (small solid parts (infill 100%) for technical use with highest possible precision). Then I created this material in the “Preferences” window (Cura->Settings->Material->Manage Materials )by duplicating the Ultimaker PLA to: Display Name -> “Polymax PLA” Brand -> “Polymaker” I left Material Type, Color, Density and Diameter unchanged. So far, so good… But now I want to edit *Properties in [Tab] Information (e.g. Density and Cost) and several values in [Tab] Print settings by first clicking [Edit] and then changing some values. *(Going to -> Settings -> Material -> Manage Materials, then arriving in the “Preferences” window) But…. After editing values, then closing all, even Cura and then re-opening Cura and Preferences I find the changes I made undone!!! Exporting and re-importing profile gives no solution, grrrrrrrrr! And why are some Properties (e.g. Filament cost) grayed out and therefor anyway uneditable??? What am I doing wrong, or…… what is the real problem? Might it be due to the fact that Cura 2.1.99 is Beta? (Why called 2.3 on download?)
  8. Hi, I am also a starter with an UM2+, just a few weeks busy. Because I mostly want small technical parts I use (the better, I believe) Polymax PLA from Polymaker. Then the nozzle 0.25mm, a 100% infill, 220deg. nozzle temp. and, however given as optinal, a bed temp of 60 deg. Fanspeed 50% I also recommend the use of (Dlac) hairspray, just a very little bit on the plate. This gives me very fine, sharp edged, good removable parts. Good luck
  9. Hi Sander, Glad I’m in the community now and be able to learn from all that input! To answer your questions No, because still being in the middle of building, even somewhere redesigning it, but it will get 3d printed parts, created in Inventor (Autodesk) And the still unused PET I have in da house is the refil recycled (yes!!!) filament. In the meantime off waiting on the first reply (was yours, THANKS!) I already learned more of using PET, which seems to be not very easy. But we will learn, 0.75kg to spend! Might it be that you know of better PET(G) than please let me know, for my applications are mostly of a technical nature with high demands, I am glad to be able to use a 0.25mm nozzle and 0.04mm layer thickness!!! With Polymax PLA very good results with small parts (as far as I can judge) Thanks again! PS I hope I uploaded view sample correctly (also first time)
  10. First of all: I am an unexperienced (2 weeks) 3D printer operator Had already good results with Polymax PLA, but..... Now I want to apply PET filament in my Ultimaker 2+ but cannot find it in de Cura Material drop list. What do I have to do to make printing with “correct” print parameters for PET possible? Is there any way to add materials in that Material droplist?
