Answer to "Ninja flex jamming in Hemera"Hi all, After installing my hemera on my anycubic chiron I experienced the same issues printing flexible filament. I seem to have fixed it with a number of small tweaks: (1) Ensure the heat paste is applied to the section above the thread as well on the heat break as I discovered filament was softening in the upper heat break and causing friction. Make sure you clean any excess off after reassembly. (2) Polish the filament entry into the heat break, mine had a rough finish with a blunt burr which was grabbing the filament if expanded due to compression of the feed. (3) Reduce the drive tension to ~10% to prevent flattening of the filament which binds on the entry of the heat break. (4) Feed the filament from above the printer with as little resistance as possible, without the small pfte tube. After doing this I could print 85a tpu without issue inline with what you see on YouTube. I hope this helps.
