Welcome to the forum. As has been stated already, the amount of knowledge and expertise available is practically limitless. Also, there is no question that won't be answered multiple times (personal experience). A couple of things that I experienced when I began scrolling. First was quality of machine. I began with a bargain basement saw which was noisy and hard to obtain correct blade tension. Upgrading was the best thing that happened to me (it may or may not be a need or option). Secondly was blade selection. I never realized the wide variety of blade brands and types. It is so important to try a selection to find the brand and type which will work for you. This is the place to come for advice and opinions. Finally, starting out with relatively simple patterns will minimize the frustration component. There is a real satisfaction to finishing a piece correctly even if it doesn't include large amounts of delicate fretwork.
Anyway, I hope it takes for you this time. It's a great way to spend a lot of time.
