Hi, I wanna make a CNC machine/Router (mostly for wood), but having a short budget i'm tinkering on ways to do it as accessible as possible. So normal Aluminum profile instead of V-rails and this kind of wheels (picture below)...They are POM wheel with single bearing I think. Whah kind of problems I'll face by doing it, in comparison to the V-slot system?...The idea is to build sort of an Ox esque machine, with 20x80 profiles (nut 5, non V-wheel). Thanks! K.
