Am trying to get my printers to work with the Colorfabb PA-CF Low warp filament.
So far, unfortunately, without success.
Layerheight 0.20 mm as per Colorfabb recommendation.
Printtemp from 255 to 285 degrees Celsius.
Retraction from just 1.0 mm to 4.5 mm.
Cooling fan from 0% (mostly) but also 10% or 20%.
Printing at 30 mm/s to 40 mm/s.
But no succes so far.
Nozzles both brass and steel, 0.4 mm.
Printers Mankati (once) and two Creatbots.
When heating up, the filament flows freely from the nozzle.
But after about 10-15 minutes, the flow becomes irregular.
When I pull the filament, the tip part looks very strange as you can see in the picture.
Have not seen any filament behave like this before.
Any one any ideas on how to get this working?
