Gotta be something that can be done. Perhaps a better formed PTFE tube up to the gears. Will try something softer tomorrow. My print came out great, albeit a little string. Changed k to 15 and disabled retraction. So far half way done and it looks clean as can be. So perhaps their is hope. I am happy so far for my first two attempts, and in all fairness I was no expert on FF before.laird.p wrote: ↑Jan 25, 2018 4:40 amI have printed NinjaFlex, but I had to slow way down - 10 mm/s! 20 mm/s generated back-pressure, followed by the filament coming out the side of the extruder. The issue isn't the BondTech gears - they are great - I think it's that the filament path isn't fully constrained around the gears. Well, and of course, that NinjaFlex is absurdly soft.
