There should be an option some where in VersaWorks that lets you set a dry time, let me poke around a bit and see if I can find it...
edit: It's under Job Settings > Printer Controls > Other Controls, You have to select "Use Custom Settings". Pretty sure that'll do what you want. Depending on the material though you may want to turn the heater down since it's gonna be sittin on there for a bit, I've never used that feature myself so I'm not sure if the heater stays on to assist in drying, but I would assume it does.
