Mark, similar but your illustration showed the affect of roller not being parallel to the table but what I am suggesting is possible with roller that is parallel and is much more likely to occur if the board is tall.
Main point being, I would not use what OP is using for setting up the machine. It is fine if he has done the basic calibration and is now trying to make further improvements. But we have not heard that.

Unless I was using this type of material all the times, I think it is not a good size for setting up the machine. I would use ~1¡± to 2¡± thick board. 4¡± to 6¡± wide and at least 4¡¯ long.
BTW, my Woodmaster did this skewing sometimes and I never worried.

One can also hold the end of the board until it gets picked up by the infeed roller. Then let go and see if the cutter head contact makes the board kick or hold it until outfeed is engaged and let go then.
Again, it would be nice to know if long boards do the same.

Hi Dave, I've adjusted it per the instructions given by Felder making sure each side is "exactly" the same (my gauge goes down to 0.01mm accuracy), but I am also thinking that perhaps the 0.3mm delta between the cutter tip and the outfeed
roller perhaps is too much.? In other words perhaps it isn't just "kissing" the board but exerting too much force as exemplified in Mark Thomas's response just below yours with the cool graphic.? Oddly though at the same time, when I have had the highest tension
on the outfeed roller compared to the infeed roller I've seen less board kick.

The only time I get snipe is when I forget to lock the table.? If
it? is unlocked the table can wiggle.
There's not a lot to do in setting the planer up.

out the? cutter block for? shellix?? re assembling it was pretty
straightforward.
I am little?? confused at the? reference to feeler gauges.? What
are you doing with? feeler gauges?
I use a standard machinist's test indicator in a movable stand? I
set the jointer tables to be co planar and the? outfeed to be dead
even with the? TDC of the cutter.
No tapers no snipe? no issues.

I ordered my C3 31 on 12/29/2019; received it on 1/24/2020.? I've
been trying my level best to set it up and have not been able to
get the planer to stop kicking and/or sniping boards.? I've worked
with tech support and now a field tech has been working with me as
well over the phone and email.? I've been using very accurate
gauges (0.01 mm) and have sent photos and videos to the Felder
staff multiple times over the last few weeks without any success.?
I am at my wits' end with this machine.? I've filled a large dust
collector bag already with just the chips from attempting to
adjust this planer.? I'm about ready to tell Felder they can take
the machine back and I'll go with another brand.? I've setup other
machines previously and never had anywhere near this much trouble
and never had to spend more than 6 hours adjusting even much less
expensive and/or sometimes poorly built machines (Harbor Freight,
Grizzly, Dewalt, Steel City, Delta, etc.)
Has anyone else had problems like this or struggled this much to
get a new machine to work properly?

Re: FB610 bandsaw blade position on the wheels: in the middle or near the edge?
David, ? I love that old iron.? I live out on the edge of civilization so I don't have ready access.? ? Short story.? In about 2004 I bought a used, cheap Chiuting thickness planer. It produced smooth, flat, evenly thicknessed boards with horrible snipe.? I traded in on a Felder. ?  ? ? Last week I bought a 20" Oliver band saw directly from Oliver in Seattle. ? ? 
? What do the machines have in common??? I learned in the process of buying the Oliver that it is the store front brand of Geetech, aka Chiuting.? According to Bloomberg, another familiar sounding name, this is a publicly traded Taiwanese company.? Their customer list includes several woodworker recognizable names such as Jet, Powermatic, Laguna, Wilton, Sawstop, Grizzly and a bunch more.? Then there is also metal working machinery, plastic injection systems and other lines beyond. ? ? ? The amount of Chiuting design content that goes into a given machine undoubtedly ?varies according to customer and contract.? Laguna and Oliver share some common dna but ?are not twins.? Its more than just sharing castings or grades of castings.? Its much more complicated.? An Ancestry.com ?(Incestry.com) tree would be interesting.? ? Check out Oliver at the IWF.? They make nice machines.? Maybe it's based on experience gained from other brands. ? ?

Your C3 31 is similar to my MinMax CU300 in that the planer table is supported by a single column.? It's hard to tell by looking at the pics, but it looks like there are 4 bolts at the bottom of the column...? ?So, have you checked to see if the 'table' is level/parallel with the cutter head?? (I had to shim the bolts on mine using copper shim material that I bought from Amazon).
Same thing with the shaper.? I had purchased a brand new set of Freeborn cope and style cutters and was getting a 'loose' fit.? I even sent the cutters into Freeborn to have them checked.? Turns out the shaper spindle was not perfectly perpendicular to the table and again, it needed some shimming.? I think anyone who purchases these types of machines needs to invest in some good straight edges and something like the Betterley Una-Gauge

The saw now hums along with just the noise of wind from the fly wheel and blade. But I now notice another phenomenon.? The saw vibrates a lot more than any of my other Felder/Hammer machine and it seems to alternate between period of less vibration to more vibration.? It is low frequency vibration that I can feel placing my hand on the cast iron table and visualized looking at the chassis or blade guard.? I am wondering if this FB 710 is suffering from the same problem as Bill Belanger's FB510?? I attempted to make a video, but without a tripod, my unsteady hand only adds to the vibration.?? I am not sure if this vibration is "normal" and may go away once I run some lumber through it.? My old 14-in Rikon does not exhibit this behavior at all.? Not completely balanced fly wheels??? SW

Re: FB 710 lower fly wheel noise at full speed
The cause of the noise in the lower fly wheel cage is due to misalignment of the motor pulley and fly wheel pulley.? I put a 1-inch Lenox Woodmaster C blade on the FB 710 this afternoon, applied tension, turned it on and the noise was present.? Proceeded to de-tension the blade, loosen the 4 bolts holding the motor to the chassis, the belt tension bolt, and the set screws (2) for the motor pulley, moved the motor pulley, re-tighten everything before powering on.? After a few attempts at small incremental movements of the motor pulley and repeating the before mentioned process, the problem is resolved.? The saw now hums along with just the noise of wind from the fly wheel and blade.
