Welcome to the forum!
I agree with Moini's suggestions, for the first thing to try.
But I wanted to ask about estlcam. I looked it up, but it doesn't give much info in English. From the website, it looks more like an editor. It doesn't give a clue that it can produce gcode. But I did some further searching and found there are a few different versions of it around the internet. Is gcode the only kind of code it creates for CNC? Or does it do more?
Even though I don't have a woodshop, much less CNC, I've been trying to help Inkscape users with Inkscape's gcode tools extensions. So far, afaict, Inkscape's extensions are somewhat limited. I've run into a couple of people who can't find the right kind of gcode for their project (in Inkscape). So I've been hoping to learn about other programs I might suggest. It's not free, but at least there's a trial version.
