  1. -- Issue solved --- I found the root-cause in the z-steps/mm settings on my Ultimaker Original with original heatbed (use the Ulticontroller Control > Motion) - old: +0200.0 - new: +400.1 I have saved the settings then via Control > Save or store memory. Source / similar issue:
  2. Many thanks gr5 for your feedback. I have not updated the firmare of my UMO recently. Also I had not seen that issue in the past. I have made some slicing tests with Cura 3.4.1. and compared with 3.3.1 when slicing for UMO (incl. heatbed) and for UM2+. Very interesting results which may show an issue in the slicer in Cura 3.4.1. Below you'll see the calculated slicing times which are odd for the UMO in v. 3.4.1 as they differ by almost 80-100% for an UMO vs. the time for an UMO2+: Example STL 1: Cura 3.4.1: on UMO: 3:18h on UM2+: 1:41h Cura 3.3.1: on UMO: 1:59
  3. I experience a very strange behavior: prints are getting "strechted" in z-direction. It looks like the z-axis is moving downwards more than wished / defined. Printer is UMO+. I used Cura 3.4.1, layer height was set to 0.2 mm. Actually in the past few weeks I had often prints with not bonding layers. I assume this is related to the z-axis issue. I have never seen or experienced such an issue in now 6+ years experience with UMO printers. Any ideas what the root-cause could be and how to fix it would be very much appreciated. Or anyone else with the same problem? In the image you see
  4. Save dialogue in Cura 3.4.1 on Apple Mac OS X looks very strange Since the last version the save dialogue box looks quite strange and has not the standard user design that I'd expect on the Mac. Why is this and will it be fixed / change to the standard design? See screenshots of the save dialogue in Cura 3.4.1 and Excel attached as comparison.
  5. I couldn't find a setting in the new Cura 15.06.03 to add an Ultimaker Original with heatbed upgrade. Anybody knows if this machine is supported at all or which settings would be appropriate? Any suggestions much appreciated.
  6. One month ago I got the white Teflon coupler from Ultimaker (warranty). I have replaced it together with a new nozzle which I had in stock. Actually the underextrusion issues have vanished since I replaced both parts. Since once month the UM2 is working smoothly. No similar issues occurred since then. I will watch this carefully, as only replacing the nozzle did not help a few months ago. After a few weeks it got blocked again. Now with the new white thermocouple it seems to have gone...
  7. Hi all I have an UM1 since 2.5 years and since Feb. 2014 an UM2. With the UM1 I have no problems resp. could solve any feeding or extrusion issues on my own. I work with Cura 14.07. On the UM2 I have underextrusion problems and nothing helped so far. I am desperated.... After 3 weeks in use with the same original PLA of Ultimaker suddenly the prints showed little holes in it, that look like underextrusion. I did heat up the nozzle to 260°C for 10 min, I disassembled the nozzle to cleat it... Nothing helped. Four weeks later I received a replacement nozzle from Ultimaker. The new one worked
  8. Hi Daid Many thanks for the explanation. This solved my problem. I have just set the "initial layer thickness" to 0 (i.e. the initial layer will print the same height as the set layer thickness). I had the same problem and was wondering why the skirt showed up with specific layer heights and with others not. Thanks and regards, Jochen
  9. I experienced that in 14.03 not always support structures are created, regardless which setting of support is chosen. Attached link to an example of a simple figurine created in Tinkercad where the "arms" are not touching the build-plate. No support structure is created which results in an unprintable part... Actually I don't know if this worked in a prev. version. https://tinkercad.com/things/fbgqNdOuRd6-lauras-figurine
  10. With the recent firmware update in Cura 14.03 for the Ultimaker 2 the pause function has been added. I tried it and it works great. The printed moves to the zero position (left front corner) when paused. After resuming it moves exactly to the position where it has stopped and continues printing. Really great stuff! I tried today to pause a print on the Ultimaker 1. But compared to the UM2 pause, at the UM1 the printhead stays at the position where it just is and stops printing when paused. Impact: the hot nozzle melts the printed object below slowly away and hot filament comes out of the noz
  11. Thanks @illuminarti. Too funny, didn't realize that in the previous version... All right, "issue" solved :cool:
  12. Just tried the new version of Cura 14.03 on a Mac. I realized that the field for setting the temperature has gone if you have an Ultimaker 2. If you select the Ultimaker 1 the temperature field is still there. Is this a bug or why has it been removed?
  13. Many thanks for your answer. Question regarding the Marlin bulider. I don't exactly understand the difference between the Ulticontroller and the Ultipanel. I have the Ulticontroller from Ultimaker. Which setting do I need? Thanks in advance.
  14. Firstly I'd like to thank the Ultimaker team for the Ulticontroller which is a great improvement of the whole process and of controlling the print. Sometimes when I insert the SD card (which was delivered with the controller) the Ulticontroller seems to hang, nothing is displayed. Only by switching the Ultimaker off and on again the display will show up again. Maybe it is required to insert the SD card when the printer is switched off.
  15. 3.5mm as inner diameter is astonishingly wide. Officially, Ultimaker gives the dimension of 1/8 inch (= 3.175 mm). Good to know that 3.5mm also works.
