i started 3d printing 2 years ago and quickly learned a lot about it my first 3d printer I worked with was 5 robo 3d printers not the best but ok then I got an x1c my first personal 3d printer about one year later I got an a1 mini without ams but then 2 months later I got an a1 and ams lite so now I have 3 3d printers that's a lot for me but for some people its not(I am working towards a second a1 mini)
