Dewalt Clone is correct - amazing how much less vibration compared to what I've been used to. Simply amazing - just trying to get it set up perfectly square - that's the real challenge I'm having right now. I keep using a little square on a tight blade to try to get that thing lined up and it seems like I can get it oh so close... but when doing 3D cuts, it's obvious it's not square. Either that or I need to use softer (and thinner) wood.
I normally use soft woods like pine, poplar, and butternut for my 3D work. My preferred blade is the #5 FD polar blade. Replace them often. I "try" to cut at full speed which helps minimize blade deflection cause my lateral pushing.
To check my square I use a block of jointed wood (2x4). While making sure you are flat to the table lightly touch it to the moving blade. Then turn the saw off and flip the block over and touch it to the back of the blade. If the blade square it should fit into the kerf. If not it will show you what direction to move.
