X axis linear rails

JRG’s advice is right on. I could hardly move the carriage along the X axis when I first assembled my machine. I had to put all my weight into it to get it to move. It was shockingly bad and disappointing compared to a machine I had designed / built using linear rails. So, I followed a similar procedure to JRG and the carriage moves way easier. I can give it a good push and it moves a foot to 18 inches. I would REALLY like to hear from everyone as to how easily their carriage moves along the X axis for comparison and piece of mind. I still think mine is not as smooth as it should be.
