One reason I am vague about settings (aside from the forum rules @eflyguy pointed out) is that my experience has shown that each machine and each piece of wood can perform differently once you’ve left the realm of the tried and true PG settings and materials. Other people’s settings are really only useful as a starting point, and you end up wasting LESS materials if you take the time to nail down your settings first. I’m currently my own proof of this, as I got a replacement machine after having a small fire, and the new one requires different settings for my intricate cuts than the ones that worked for me before.
Here’s a post that can help you with testing – it only takes a small 1/2" strip of wood, and you can save it for future reference, so it’s not “wasted.”
