Hi,I am an amateur with not a great knowledge but I am eager to learn. I have BCN3D Sigma 3D and everything was alright until last night when the printhead clogged and made it impossible for the filament to flow freely from the nozzles. More so, the material started leaking all around. I quickly turned the machine off, cleaned but to be honest I am little concerned to turn it back on. Is there anything I should check? Did I screw something up or is it something that can happen?
