Hi All, I just tried a new xml profile for my machine which seems to be setup much better than my previous one, however when I click home it tells me the selected homing switch is in use. what is this and how do I change it? the machine was homing just fine with the standard mach mill xml file. thanks!

Sounds like the active state for the home switches may be the opposite of what you had previously. Have a look on the diagnostics page and see if the LED for the home switches are lit when you are not on them, if they are then go to Config menu then Ports and Pins then Inputs and change the active state for each home switch you have. Then go back to Mach and  pres the reset so its not flashing then press your switches manuall to check they are coming on when you press them.
