Actually I had 2 of these robotic libraries and both had a ~5' rail and a shorter 2.5' rail. So I decided heck a ~5x5 table is more than enough for my shop so I just used the two longer rails. The only part related to the gantry i've had to buy was the Z axis and the longer belting to drive the X axis from both ends. Heck the tape libraries even had the jack too.. |
