@Peter, I have an old Robo R1 with slider rail heated bed version (March 2014 delivery). The Robo 3D forum is great and has many great contributors who can help other users. Had upgraded quite a few things too. It was printing ok, but not quite great. I have spent more than $1000 (printer plus other upgrades) and now my controller board died a few weeks ago. I ordered a replacement board but had not replaced it yet. I believe that you were one of the very few users who were fortunate to receive good quality Robo 3D printers out of the box. I saw your prints and they look fantastic. I like the design and build of the CraftBot. The design and build quality look superior to Robo 3D. And if it can print as good as the link on the last post, then it'll be way better than my old Robo 3D printer. Another thing, why would anyone want to own two same printers when they can own different printers? I see other users here either bought or built other printers and they seem to like the other printers as well.
