Shorai Multibot

I am building a multibot 3D printer, with somewhat similar features to the one by @Shauki on Maker Forums and OpenBuilds. Please click 'Read More' below for full details. Shauki's  Multibot on Maker Forums Shauki's  Multibot on Openbuilds Shauki has done excellent work and has made great contributions not only in this and other projects, but also in getting me to think about what is needed and possible. If anyone else is working toward these or similar goals, I would like to collaborate with you and welcome participation (to a point, I only have one body, one mind, one wife, one mother, 4 children, one grand child and one dog, all of whom require my attention from time to time). Design Goals Obviously I have different design goals from those of Shauki, here are the important ones in no particular order. This is essentially a Fused Filament Deposition Printer Everything must be pluggable, replaceable and instantly upgrade and downgradeable Significantly
