You never want to complete a hobby project 100%. That last bit is just too boring compared to the shiny shiny new idea.
It is never going to be 100% complete as hobby projects are not based on the strict requirements from the client, and we can always find something that can be improved or added.
But when I said that is not complete, I meant that besides the fact that electronics is still assembled on breadboard, both the machine and controller missing basic functionality like end-stops switches, auto level functionality and etc.
But soon this machine will try to make PCB for it self, and if that works well, I will use it to make all my PCB prototypes on it. And I will definitely add automatic solder paste dispensing functionality.
