I am having trouble homing my X axis with my new CSMIO/IP-M runing Mach 4. The axis is set up with a positive and negative limit switch. I am also using the negative limit switch as the home reference switch. When I home the axis I am getting an X axis limit switch tripped message and the machine goes into E stop.

I believe that this is a Mach 4 plug-in problem. I am under the impression that the homing sequences handled by the plug-in.

Does anyone have an idea to solve this?

In Mach3 on General config page there is an option called Home Switch Safety, setting that to Off (I think) will allow you to share limit and home switches. 
Not sure if there is anything similar in Mach4 though.
