I’m trying to print a circuit which I should print for a hour.
For 30 min after start, the circuit is printed well but a lump of conductive ink is attached at the end of the nozzle and the lump spoils the printed pattern. I think that the ink which was printed at start became solid because of the long printing time and the solidified ink is attached to the end of the nozzle. Is there any solution for this problem?
