go home problem
I have rostock mini pro. Sometimes when I click home button one or more axis not move at the same time, and they wait more seconds (4-5) before start to go home.

If this happens only sometimes, check your end stops.
With M119 you get the status of your end stops.
Sorry for my poor English sometimes I mean not always but it is very frequent.
All end stop are in low state in this situation. (End stop are in high state when switch)
