Hi all, I originally signed up on this forum because I had tracked down some users with an extruder that I am investigating. But, as I look at the Robo3D I'm thinking it might make a good addition to my stable (7) of printers and would be perfect for taking to fly fishing demonstrations (I developed, sell and give away the STL files for an all=printed fly fishing reel, see my avatar) to sit next to a mini Kossel delta printer. I have some basic questions on the R1 that I can't find on the web site. What technology is the auto leveling? It looks like the nozzle touch is the trigger. Is it using FSRs (force sensitive resistors) or is the bed sitting on mechanical switches? What firmware is it running - looks like Marlin but maybe Repetier? What hotend is included? Very interesting machine!
