Just added a Bambu H2D to our fleet (own other Bambu products) primarily to run carbon fiber filaments. Our first print is with the PPS-CF. We pre-treated the filament in our Sunlu dryer at 110C for 12hrs and I now have it still drying at that temp and running directly out of the Sunlu unit to the left extruder. There is a spot about 2-3" above where the tube actually enters the extruder that the filament is struggling to bend. I was able to disconnect the tube to get the filament fed, but shortly into the build the filament snapped there as it’s being flexed at a pretty good angle when printing the part.
What are ya’ll doing to create a more gradual path for the filament tubes for these stiffer materials?
