We are using the voltera machine in our laboratory. The problem that we are having is that all the needles are broken after printi a circuit. We use acetone and just after the printing of the circuit, we introduce the nozzles in the solution. However, when I plug ir again the conductive ink doesn’t come out thru it.
How can we properly clean the tips because we are feeling very dissapointed with this system and all the nozzles are being broken.
