thanks, now it works better, but theres no other support material that can be dissolved in water?
i mean after all, is not so easy to print with PVA, and what i hate most is that i need to clean the nozzle so often! because it doesn't sticks properly, the nozzle catches the PVA that wasn't attached properly to the layer, and it stays there in the outside of the nozzle and it turns dark and sticky.
