Hi everybody, I'm new on the forum. .I'm actually designing a 3d printer based on Prusa I3 model, personal project. .I chosed V-slot system for X Y Z axes because I love the system. In a discussion, yesterday a friend told me plain and symply : "Linear rails like MGN12 are better suited than V-slots for 3d printers No geometry changes, less elements, no play, more precise." So I'm asking the Openbuilds community, what do you think about this ? I'm about 30% of progress in my design and today I'm lost, did I choose the right direction ? Saying that V-wheels system vibrates more than linear rails, takes more play and as changes in geometry in time, that it needs to be verified an tightened more often. And at the other side linear rails are is simpler, less elements, doesn't need to be tightened, but requires precision in the mounting. I love V-slot, but what I need are the lesser vibrations in the system and absorption in jerks. I thought the Wheels system whas the best because there were "no" friction displacements but rolling displacements among all the other advantages. I need help, could you answer me please ?
