these minimills are fun. A nice way to make small parts for model trains etc. but just too small for RC controlled models. I've been thinking of buying one of these at the "intermodellbau" fair I visited last week. Proxxon had a 10% discount on the machine and usovo was also at that fair with their ATC kit.
Almost bought one, even if only to play around with the tool changer, I really want to know how they do this.
