Since a year and a half learning all about 3D-printing. As a newbee then it was difficult how to and where to start in the 'big wood' of 3D-printing. Some time ago I bought second hand the Prusa with MMU1. Interesting I thought. Still it is, but the machine is not stable enough until now. Alsomany other problems occurred i.e. in the various softwareprogs, the supplies etc.
But: learning every day and still going strong. I will succeed 🙂
