I visited a slate factory today, to pick up samples & buy some blanks, while there we were told that they have a $50,000 laser which is sitting around unused. They told us no one uses it because when they engrave slate at the end of the day the entire machine needs to cleaned which takes hours. Is this a common problem, because by Wednesday there will be an Epilog sitting in my spare room & I was expecting to lots of slate & I was hoping I wouldn't have to revamp my whole plan for at least a week. Any thought would be appreciated. Linda
