Rails are in and we will be starting this over the weekend. We had two that started off as Betas and one has had the official bed replacement/rails and some other mods done. The other one still had the original joke of a bed with drawer slide rails Just got the rail kit in from BangGood: http://www.banggood.com/200600800mm...pport-and-SCS8UU-Bearing-Block-p-1104573.html 600 mm version (which is looong). The goal at the end is to have one of them that has the leadscrew replacement use the official linear rail bed replacement (because that bed is smaller) and the one with the volcano on it use the new (huge) bed. That one still hast the original 5/16 threaded rods as well and the other one has the leadscrew kit.
