I made a quick video to demonstrate how to scale an axis inside RMC Tools. RMC Tools is a free motion control software used to program Delta motion controllers.
Delta provides controllers accessible from the internet to learn how to program their equipment. For anyone into motion control(anything servo related), I highly recommend Delta's technology.
You can visit the Delta website http://deltamotion.com for their product line.
You can download the software http://deltamotion.com/products/software/rmctools.php
