Welcome aboard! I think you will like it here.
Well, Jarrah isn't a wood that I've ever used but, whenever using my FMT on either hard or soft wood I first make a very light climbing cut pass all the way around the part (to prevent edge splintering), followed by 1 or more forward cuts around the tenon to remove the bulk of the material. These passes are unguided (not against the guide), going just by the "feel" and sound of the router as I make the cut to remove the bulk of the wood. You should never try to cut more than 1/2 the diameter of the router bit when doing this unless you are going between multiple tenons. When I reach the guide I make an additional complete pass, pressing lightly against the guide, and then I make a final climb cut pass around the tenon while pressing a little bit firmer against the guide, to achieve a precise, clean, and repeatable tenon cut.
I've also found that when making tenon cuts on tenons that are longer than 1" I cut them at two different bit depth settings. I make the first pass at something less than 1" until I reach the guide and then I change the bit depth and repeat the cuts at the final bit depth. In this case, the final climb cut pass isn't done until the final cut at the full depth. Cutting the longer tenons at full depth produces chips that are too long for the vacuum port and they clog the port frequently. Shorter chips don't seem to clog the port.
I attached a 3/16 X 3 X 6" piece of clear Lexan to the front of my FMT with a strip of velcro along the front edge of the top plate, so that it hangs down in front of the cutting area of the jig. This blocks any stray chips that the vacuum misses from coming forward toward me and it adds a bit of safety to the jig. After having a carbide bit explode on me some years ago (not on the FMT) I have never felt comfortable using a carbide bit in a router in a way where it is exposed so that pieces of it could directly hit me. The bullet proof Lexan material should help protect me if this should ever happen. You should never look through this Lexan while cutting. Always keep your eyes above the jig whenever the router is running.
