One of the new functions in TouchDRO Plus is the Reference Image overlay in the Graphical View display. In essence, it allows you to set an arbitrary image as the background for a workspace and calibrate it to the machine coordinates. As a result, as you move the spindle/cursor, the features in the image will translate 1:1 to the physical part. There are a few different uses for this functionality. In this post, I will go over the three ways I've used the Image Overlay [so far], and then explain how to set it up on your tablet.
