Yep, you will need to check your config. Erm, it will be different with each version of MAch2! Try the input pins and input setup in the "ports and pins£ section of the config menu, then, you may also have a seperate section called "homing" in there to adjust. There should also be a tick-box *somewhere* to tell Mach2 to use the limit switches as home switches, if that is what you are doing. Also, Ref-All will ref all axis simultaneously, so your switches will need to be wired on seperate inputs, or they will all be triggered once one switch is hit. If you have this problem, you will need to ref one axis at a time, in which case, the buttons are hidden in the screen designer section and you will need to edit your screen to add the buttons manually. Few!
