While disassembling my printer, I found that the X-axis rods were able to be slide back and forth within their mounting bracket. This seems like it could lead to this axis shifting from vibration alone.
But, it might not matter, I think, because the extruder carriage is tensioned by a belt and it simply uses the rails as a guide to slide across. Even if the rods were to move, it wouldn't take the carriage along with it.
Will the X-axis rods sliding in their mounting bracket have an affect in print quality?
