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

Hi future readers, Good settings. Used them to refresh my memory after a year of not printing NinjaFlex.
