Hi all ,
 Just joined this forum and I need help badly , I have converted my x3 mill to cnc using fusion kit etc, I am using a G540 and nema motors purchased from Peter Homann Designs   and all axis move ok , I have mounted x+ - y+ -  and z + switches and checked these for home as well , my problem is in diagnostics all switches work ok , I have also checked auto limit overRide Limits when I ref an axis it travels to the switch and stops wont back off , all limit switches are in series to ground all wired as per Homann diagram . I am very new to cnc and Mach 3 Any help would be greatly appreciated .  
 Thanks Brian
