If you have downloaded kmotion software the info is there just hard to find. First open the kmotion help file. Then select the kmotioncnc file. At the end of the file under the heading "Other g-code commands" is a link to the "emc user manual". Once you open the emc user manual before clicking anything else choose click the word "contents" at the top of the page right side. Scroll down to section 3-11. It is a list of the available canned cycles as well as a description of what it does. There is a lot of other information under the contents menu that should help as well.
