Do you have another printer to test it on to see if you have the same issue happen? I have been troubleshooting a problem similar to that for a while now and so far i haven't found any rhyme of reason why it happens. I have 3 delta printers all using ramps 1.4 with the same marlin firmware and one of them does it the other two dont.
