  1. TweakAtZ Version 2.0 should work with Cura 13.11. However, this version may have its problems if you have some z-changes in your Start-GCODE. If you want to tweak a parameter at low z, it might produce a 'jumpstart' due to the z-lift at the beginning...
  2. Did you really then set all the line widths to 0.4mm? I tried that some time ago and got very bad results for the infills (single lines with gaps). I then reset these to 0 and got results quite similar to those with Cura.
  3. feel free to watch it all night long... :wacko:
  4. I did a quite large print yesterday for which I used a 10-lines-brim. This is just the brim and the outer shell: Some layers later: I think the brim looks quite ok but maybe some of you will call me a fool... :shock:
  5. I fully agree with Nicolinux. This piece is amazing! And thanks for the information about the used material...
  6. @gr5: yep, I do... btw: I really like your new profile foto... :cool:
  7. I have the impression it got better already from 13.06.4 to 13.10. I have a test print that takes 9:29. Cura 13.10 says something like 8 minutes, Cura 13.06.4 had very optimistic 3 minutes... however this is on a Windows 8 machine...
  8. Although still using the standard unheated bed I use Kapton tape with a width of 200mm. These are the pros/cons: + VERY smooth surface of your prints +/- reasonable adhesion + no joint of the tape stripes visible on the print + PLA warping doesn't loose the tape from the bed + the same tape can be used much longer than the Painter's tape + no degrading of the adhesion after some prints - changing the tape requires some time It is often mentioned that Kapton tape is more expensive than the blue Painter's tape. I'm not sure this is really true. I think the widest blue Painter's tape you
  9. Hi Daid Congratulations to all of you at Ultimaker. Bringing a new product to life isn't easy and it doesn't get easier if it's the second one. Especially not if it's not for the same group of clients. A lot of people already mentioned what you should do in future, but you also asked what you should not do. As I see it, you have limited man-power for R&D. Use them wise. Don't start something too big like creating your own CAD software or similar. This is not your core business I guess. From this point I think R&D should take two directions in hardware for the two products. Try whate
  10. RicardoGA updated the TweakAtZ plugin so it should work with the current Cura version, see: http://umforum.ultimaker.com/index.php?/topic/2454-cura-13064-plugins/
  11. Recently I had serveral breaks in PLA filament (not from Ultimaker) which was still mounted to the Ultimaker but not used (therefore stayed at the same position). It's clear that (standard) PLA is a quite brittle material. But these breaks did not occur when the PLA was 'fresh' out of the plastic. Of course I had to twist the filament by 90° between reel and bowden tube. The room I run my Ultimaker has a temperature between 19 and 25°C and a relative humidity of 50-60%. I would like to ask the PLA experts among you what might be the cause for these breaks. Humidity? Too much stress in the f
  12. I had my clog in the brand new hotend between the Teflon part and the brass tube. As far as I can see, the hotends are not well clamped by the wood parts in the Dual setup (compared to the Single setup where the bottom plate is fixed to the rest of the wooden part of the print head). There should be a better way to control the spacing between the middle and the botton plate of the print head as the bottom plate clamps the Teflon part... I'm currently thinking of adding four springs between middle and bottom plate to push the bottom plate down...
  13. Thank you for confirming! I thought the 16mm might be a bit too much... I'll try the tower/wall thing. However, if one uses a tower for each color, switching off the heater for the second extruder isn't an option anymore... B.t.w.: Does anyone know if there will be a new stable Cura version comming soon? Maybe on the 21st? Maybe with the extended support material structure some people already tested?
  14. After having upgraded my Ultimaker with the Dual Extrusion Kit, I ran into my very first clog today after having run the Ultimaker for quite some time in a single extruder setup without any clogs. As gr5 pointed out in a previous post (http://umforum.ultimaker.com/index.php?/topic/3022-ultimaker-suddenly-stopped-working/?hl=clog&do=findComment&comment=22238), it can happen if the PLA stays inside the heated hotend for too long. With the dual extrusion this situation becomes more likely. For larger prints at small velocities, an idle time of up to 10 minutes becomes possible. Has any
  15. If you just want to print one color in a single run, then it can be realised by a Cura Plugin.However, if you want to print multiple objects in one run with different colors, then it gets a bit tricky... but not impossible with some restrictions...
  16. Then I guess you may find it with a multimeter checking the resistance and the connections... :wink:
  17. I'm not sure if I got you right: do you get a different temperature reading from the Ultimaker compared to a external measurement?
  18. Just being curious: do you see the missing parts in the Gcode view of Cura? I had once a print where some thin walls (0.8mm if I remember correctly) were missing as well. They did not appear in the Gcode view as well.
  19. Daid, thanks for the information. Please let me know if I can help you with tracking it down...
  20. Hi there Today I wanted to switch from 50mm/s speed to 100mm/s, something I've done before w/o any problems. I was then very surprised finding my Ultimaker rush at nearly light speed on the first layer as the bottom layer speed was set to 20mm/s. After having tested around with old Cura settings, I found this configuration to work properly: Basic settings: Advanced settings: Expert settings: There are no plugins activated, but present in the plugin folder. Then I tried to change the Minimal layer time in the Advanced settings from 5s to 7s. The result was, that the speed for the fi
  21. I agree on Blender's (non-)precision... And Cura is doing a fine job usually (no offense...), but I'm just thinking of those people who now buy the Ultimaker2 as they are told it's plug-n-play. I think the software is a major piece in this 'one-button-3D-printer' puzzle. And it has to be almost fail-save for those people...independet of the model's quality as non-experts will certainly deal with non-perfect models. It may be a very simpel idea, but what about giving the user a choice? Cura could for instance slice the STL three times, once the 'normal' way, once with an offset of +something
  22. Sometimes Cura 13.06.4 makes strange things when dealing with a horizontal surface created in Blender: The layer height was set to 0.1mm. To me it looks as if Cura interprets a z-position of e.g. 3.00001mm or similar as >3mm and adds a new layer. Depending on the program used to design a 3D model such artefacts may appear due to the numerical precision. To check this hypotesis, I moved the lowest z positions up by 0.05mm in Blender. This is what I got: Yes, this is what it should look like... To the Cura designers: Is there a possibility to make Cura a bit less sensitive to such mi
  23. You're right, I mixed it up with another issue... sorry! I was lucky the tension was just enough when I moved the x-motor as far as I could along the holes. Did you use threadlocker for the motor screws? That looks very promising...! Thanks!
  24. Sounds familiar to me. It may come from the unevenness of the bed. Are you working with the standard Ultimaker bed? Ideally the cross-section of any line drawn would be a rectangle with the layer height and about the nozzle size (or a bit more) as width. If there is a valley in the bed, the cross section of the line becomes more like a half circle or similar. Consequently it becomes narrower and could detach from other lines. However, the effect should disappear after a few layers as the height difference between last layer and the nozzle balances out... So maybe a re-check of the bed leveli
  25. I just realised that the FlowThermostat plugin is not working properly. It lacks to get the correct z position with Cura 13.06.4. I made an updated version: https://github.com/Dim3nsioneer/Cura-Plugins/raw/master/FlowThermostat1.1.py
