Agree with Jonathan keep playing with DOC and you'll find the sweet spot for your machine. Be aware it will also change depending if your Full slot cutting or Side cutting so often you'll need to find a balance depending on the job and how much it goes in or out of full/side cutting.

A good clue to cutting correct is to check heat of material and chips.? When your cutting correct the Chips will be scorching hot but the material just slightly more than warm.
When your more experienced you'll here the sound and know if your close to cutting correct but at the moment these sounds will probably be
making you nervous and weary.!! . . .Put some ear plugs in and listen to it you'll not be quite so on edge and it dampens mechanical noises and lets you hear cutting sounds better.!!

Also Set your VFD to display Amp's rather than RPM this will give clue to how well cutter is coping, also shows when cutters getting worn while jobs running. If Amps are low while cutting then this gives a clue that you can probably take deeper cuts.

Regards sticking then Mix some paraffin and old engine oil in a squirt bottle and give the cutter a blast every now and again to help with sticking but when you have found the correct chip load blown air is enough to clear chips and stop re-cut/sticking. I never get sticking and for most Jobs only use blown air with few squirts of coolant, for jobs where finish matters then I run a mister system. (just can't bloody breath when it's at full chat.!!)

Now test it properly for accuracy and cut the Aztec calendar.!! . . . That sorts the Baggy fanny's from the tight chuff's .. Lol
