  1. Hi all, and future readers, Oil might help but this is easier for the long run: ** Buy Yourself A PTFE Bowden Tube ** On my UM2+ I have printed NinjaFlex with mixed results a year ago. Last week I used it again for a new project and had difficulties finding the right settings. Adding 5-10% flow is essential but also on high temp and freshly cleaning (atomic pull) nozzle worked well 1 print, failed the next one etc. Under extrusion from the start or suddenly after quite some layers. With the clean nozzle the only problem could be the feeding. Cleaning the feeder and fresh undented Nin
  2. Hi future readers, Good settings. Used them to refresh my memory after a year of not printing NinjaFlex.

  4. Hi all, Getting more experienced with my UM2+ every day and have encountered and solved loads of the beginner problems, often with great help of this great community over here. Very very helpful. A question that I cannot find yet on the forum (correct me if i'm wrong) is if there is a way to have a layer countdown timer on the LCD display. The load bar and countdown timer is of course the most useful indicator to see the status of your print, but sometimes it is very usefull to know the layer height: - If you see a problem occuring with the print or printer, you cannot know which layer to c
  5. In my experience you can gain most by sanding the rubber contact surface to be glued. As with all (non-printed) rubber parts to glue, increasing the surface on micro-level by sanding will improve the bond. Smooth surfaces are the hardest to glue, especially when the solvent in the glue does not work on the material itself.
  6. Old thread, but always new viewers using the search command: Reprapworld.com is selling the original Ninjaflex and semi-flex. = Low shipping costs for the Dutch community and countries closeby. Works perfect for now on UM2+ (240 degrees, 20mm/s, no retraction). Only printed relatively small parts untill now though. Cannot judge for bigger parts.
