Hello Stuart, the Help doc button in the screen in Mach4 has that particular document for the touch module. We have been working towards this for some time time now. da40flyer has both the Doc and the video but is still has some questions. He has done what we would like to see, he read the docs, watched the video, and now is contacting the Support team Via the help desk to help get over the hurtle. Many users do no know that we have a knowledge base, or that the majority of the docs are right at their fingertips, or that we have a Youtube channel, or that they can contact us directly Via the help desk when they still have questions. I am here to get the word out so to speak so everyone is aware what is available in terms of assistance. best regards Jim.
