We're trying to minimize the number of times we flycut and also trying to maximize our vacuum holding potential on our CNC. We have a fairly new Anderson Selexx 510 that's a great machine but we're still learning.
Currently I am cutting through 0.03mm into the spoilboard (about 1.2 thousanths) on anything coming out of Cabinet Vision.
I also nest some things via CadCode that I'm having come out at 0.02mm (0.8 thou) successfully, but for folks who cut mostly melamine and plywood all day, I'm trying to see just how tight you guys have found you can go.

We go .004" deep.
From contributor Ma
We stick with. 004 as well. Super shallow is nice til your tool starts to go away. A little deeper gives a bit more protection for us but it's all a balance of the material and size of parts in the nest.
From contributor Dr
.005 except for the V point drill bits.
From contributor Ka
.001" to .002"
From contributor De
Not sure exactly what we out put it from cabinet vision at, but we will fine tune at the machine by adjusting length of tool. If we see edge is not cut all the way through, we shorten the tool length to run a bit deeper we find we have to do this as spoilboard gets thinner it doesn’t suck down the same when surfacing and we will get areas that will have a little bit left on edge. We can get 10-30 sheets between surfacing, depending on type of parts we are running

OK I see we're on the tighter side compared to most of you, since we're doing 0.02 and 0.03.
Doing 0.02 is experimental for us but is working (0.001").
Thanks for the input everyone!

We have CV set to go .03.
However, it really comes down to the operator and setting the tool height.
I use a half inch piece of melamine as a test piece and run a quick pass at .25 to determine the appropriate height.
Using calipers I measure the actual depth and adjust the tool height accordingly until i get the ideal pass of .255.
If it leaves an onion skin, I'll take the onion skin, measure it, and remove that from the tool height to get it to cut just right.
cheers

You actually are not on the tighter side at all. .01 or .02 are a LOT more than .005 or .003
Personally I cut at .005 through the material and then resurface the spoilboard at .005 "
That is 5 one thousandths. You get a lot of spoilboard out of one sheet when only removing that much every ten sheets or so .
Also cut nest strategy cones into play . If you cut small nests first to large part nests last you can get up to 20-30 sheets with this setting , vac matters too, we were pulling a 10 hp backer dry vane and now pull a 25 hp dekker liquid ring . So just play and see what works , no canned solutions here as we all have different set ups, vacs, etc...
BTW I run an Anderson as well , stratos SUP and I think it has the same phenolic bed as your sekexx
From contributor Ma
Quicktrim thank you for your reply, glad to see another Anderson user here, and yes we do have the phenolic bed.
One quick clarification, though, is that we are going 0.02 (CadCode) and 0.03 (CV) in millimeters, not inches. So the 0.02mm is actually less than 0.001".
I discovered the other day that the reason I was unhappy with our cut depth was due to a bad flycut calibration. Our flycutter is on the tool magazine and we touch it off with the touchpad. I did another touchoff with it, and now we're back to beautiful cut depth at 0.02mm.
If your machine is set up in standards, try setting your cut depth to 0.00078", which is a bit closer to my 0.02mm. I have yet to cut a material that this didn't work well on.
Our vacuum pumps are twin 10hp Beckers on a 5X10 bed.
The one thing I am not happy about on this Selexx is just how much spoilboard is left over when we are close to flycutting through into the nylon lock-screws that hold the spoilboard down. Our old machine was set up very differently (but lacked the hold-down screws) and we could get away with a 3/8" thick spoilboard before needing to change it, unless humidity warped it. We had other issues we had to work around since it wasn't bolted down, so I'm not in a hurry to skip the bolts on our current machine. I just wish I could get another 1/4" of useable spoilboard out of it without losing a lot of vacuum by having even deeper countersunk screw head holes.

.0130. CV permanently set.
40 sheets of Mel, fly cut 20 sheets 1/4” flyicut. 24 sheets of Plam. That’s 1/2 mil of spoilboard.
