Hi Ugo,
I have had some prints with z-flex before, and I have to say - no problems occured on the unload. When I’m going to unload the material I pull very slightly on the filament, just to feel the extruder gear to pull out from the nozzle at the moment the temperature was reached. When I feel no movement any more the filament left the extruder gear and I can pull it out.
In this forum I raised the question if it is possible to use the cartridge with z-flex as well and whether there is anyone who has experience on this but no answer from the experts til today.
Greetings
Uwe
