Hi, I am new to this reprap thing so please pardon me if this is a stupid question, I noticed that at here the build area is XYZ: 20x20x10cm but at here the build area is 20x20x20cm Does that mean that the first link refers to a prusa mendel i2(the website does not say what iteration is it) whereas the second links to the prusa mendel i3? I ask because the minimum build volume that I need is aby unregistered - General
