szivgy 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.
RepetierSupport If this happens only sometimes, check your end stops.With M119 you get the status of your end stops.
szivgy 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)
