Congratulations on your Striebig Joe! That was my favorite panel processing saw.
You can get two clean rips without rotating if you maintain the kerf gap with spacers as you rip. This does affect sharpening longevity, and is less efficient than crosscutting. Rather than wood shims, I used flexible plastic body filler spreaders for the spacers. Easier on melamine edges.
Some tips based on my experience:
Crosscut as much as possible. The blade prefers to work with gravity. Also easier to set the fence repeatedly for crosscuts.
For accuracy, preset as many stops as possible for rip cuts, including the trim or dust cut.
I processed almost exclusively melamine without a scoring blade. The best blade I used was the one recommended by Striebig for melamine. It was also less expensive than blades suggested by local tooling houses.
Stack cutting whenever possible will save time, especially thinner material like drawer sides or bottoms.
When you can afford it, get a digital gauge for setting rip cuts, if you do not have one. This will speed and improve accuracy especially on fence settings that are not on the stops.
Do a search on Woodweb for "Striebig" or "vertical panel saw". There are plenty of threads to cull information on vertical saw processing. I contributed to a number of them from 2009 - 2013 when I was using mine.
