I progressed with the assembly. i realised there are a few improvment to do regarding a few part ( the timming belt anchoring to the head is sub optimal and the adapter betweent the DC motor and my Belt roller is not study enough. i willy probably have to make it in aluminium.)

I also had to order a few missing part ( longer flat cable for the raspberry pi camera, DB 9 connector for the hotend )

I hope to print something this summer
