A note about sniping since I just noticed that you asked. The technique for all builds of thicknesser and weights of work is the same really, but the lighter the work and the machine, the more sensitive you need to be. So for a light workpiece, ready to begin feeding, rest the first 75mm say on the thicknesser bed, and support the outboard end of the work just with a couple of fingertips, and feel for a sense of when the end in contact is resting flat on the bed. That sort of establishes the line of feed that has to be maintained until the feed rollers can take charge.
This is mirrored at the outfeed end after you've walked round the machine. It's a flowing, organic process that you have to feel your way into, and yes there's an element of guesswork involved!
It's a procedure that can even be followed with a 4m beam, but I wouldn't be doing that on a lightweight machine.
