It does depend on what you are cutting. Most of the work I do on that machine is 12mm and 18mm MDF. Generally I use two passes, one deep and one shallow. If I use two even passes or one full depth pass I tend to get problems with the parts moving as the vacuum bed on that machine isn't particularly powerful.
As is so often the case there are few hard and fast rules. What works great for one person doesn't work so well for someone else.
