first of zero and level cylinder to concave, then take an average cob and measure it's diameter and set cylinder at the size or slightly tighter. Slow cylinder down. Old conventional rule of thumb was open clearance all the way and tighten down until all kernel removed from cob, then speed cylinder up until cracking then slow it down till cracks stop.
What is your return? Should have very little or no return. Open sieve up all the way once.
Make sure concave is clean, they can get plugged and you don't know it.
Check clean grain augers for excessive wear.
That F3 should have excellent grain quality, probably better than any new machine today so take a little more time to get to bottom of problem.
