I’m sure this has been asked before, otherwise they wouldn’t be scattered all over eBay, somebodies gotta be buying them. But I haven’t been able to find a single review from anyone who has used these. A little back story about me though, I have a zx45 from Bolton tools that I’ve been using manual for several years now, and I want to convert to cnc, I’ve read several of the build threads, and have a very general idea of what to do, but I am a complete newbie in this area, aside from messing with 3d printing and fusion 360, I know very little else.
So my question is, would this kit be worth while, or are their better options out there? Here is the link to eBay. I like that it comes as a kit, meaning it is hopefully most of what I will need, and the components will work together. But again, I don’t know much about this. Yet.
