  1. I've just removed the filament - it obviously left the section in the print-head, but it broke again as the m/c was withdrawing it, leaving a short 12cm section in the tube. I then tried bending some of the filament still on the drum. It was very varied - some bits bent almost double before breaking, and some bits snapped as soon as any bending force was applied. I guess the filament is faulty. Do you concur?
  2. My UM2 is just a couple of weeks old and I've printed only 5 models. On two of them there is a clear fault between two layers - one of them broke at the fault when being removed from the bed. After this I've noticed that the filament in the transparent tube is broken - there is a 1cm gap, which is clearly shown in the attached photo. I think that similar unnoticed breaks and gaps were the cause of the lamination faults, and that the one illustrated will cause another error in the next thing that's printed. The filament is the one included in the delivery box. Does this indicate a fault in t
  3. Thanks for your suggestions - I'll try experimenting.
  4. First off, I'm totally new to 3D printing, and this is the model I've designed to print on my UM2 with Cura 15.06.03. I made the 3D model in TurboCad V21 and converted the STL with Cura. The printed model is truly awful. I've attached screenshots of the model in TCAD, as seen in the Cura view, and a photo of the printout. Am I being too ambitious to try creating this model?
  5. Thanks for the replies. I've been away for a few days. I'm minded to printing the Roberts mods. Does scaling work properly in Cura 15.4, and if so, is there a way for me to get that version?
  6. Thanks for your response. I'm using the PLA that was in the box with the printer. After that bad layer the rest of the print was fine. Is this a fairly normal problem with 3D printers, or does it suggest a more serious root cause?
  7. I thought I'd posted this a day or so ago, but can find no sign of it, despite seeing a reply I'd made to a different thread. I'm a total newbe to 3D printing and have had my Ulitimaker2 for only a couple of days. I'm using the latest Cura 15.06.03 under Win7 Ultimate x64 and have encountered a few problems. 1). When closing Cura I get a message saying there were errors in 'Cura.exe' see logfile. As can be seen in the attached screenshot, the message tells me where the logfile is, but it isn't there. The screenshot shows the sorted folder that should contain the logfile. What'sd going on?
  8. The best 3D modelling CAD systems, as far as I'm aware, are all parametric: SolidWorks, Catia, ProEngineer, and Alibre to name but a few. They are all expensive and have a rather steep learning curve. But there's a new kid on the block: Autodesk Fusion 360. Its been out for a year or so, and is extremely powerful, plus, unlike the previously mentioned systems, its FREE for hobbyists, students and enthusiasts. It also has a rather super additional feature - T-spline modelling: its rather like moulding a lump of clay in 3D. Do a Google for Fusion 360 and have a look at some of tutorials and vid
