Hello, I'm bulding my second printer - custom 150^3 loosely based on prusa i3. (1st one was mendel90 with some modifications over the years). I have technical question about Y carriage function. As I'm planning to not having it at all =D Due to make heatbed as light as possible. The problem is I've searched different forums and couldn't find the possible drawbacks of this approach.
