It takes few hours to build and then few hours to learn and optimize it. There are many spare parts. I got one building piece in bad quality, wasnt able to put nuts inside and screws were short (see photo), it was 3D printed in bad quality and I had to cut and drill it little bit. But finally I built it and it is working. Power cable (80cm) and computer cable (50cm) could be much longer, they are not very useful. You have to place computer next to the cnc. Machine operates very noisy and makes strange sounds.
Everything is good !
