Hi. We are having several problems win this printer and it’s only a 1 year old. Last one: it´s the second time that with z-petg stucks the nozzle. First time we put a piece of cleaner filament and works again, but now nothing. Filament stops and we ear the motor trying to push it even with hand but nothin happens, filament doesn´t run. Anyway, specifications sais that it have a MATERIAL JAM DETECTION SYSTEM but the message never has appeared. We are waiting to the dealer´s maintenance personal to repair it.
We have a Anet A8 (very very very cheap printer) and it´s more reliable and better finish of pieces than M300 Dual. We throw to the waste more pieces than good ones.
We have the last firmware and the last Z-Suite program.
