We have always had ghosts in the machine but this one is a bit too consistent. We cut a flexible PVC all day everyday. On our older table(6' X 16' PRS Alpha circa 2007) we cut border so it has the least downtime. The issue is that this machine will stop and the software will close in the middle of a file. Sometimes it does this while warming up the spindle with the keyboard open. Sometimes mid cut. Sometimes 10 times a day and sometimes not one. Non of the other machines in the building do this. Any thoughts or direction will be appreciated.
