Well it arrived today and I’ve had a few minutes to work with it. Built another fixture to hold the backing plate so I can mill it down. Not exactly happy with the quality of this X-Y machine. I bought a $100 one in hopes the quality would be a bit higher but its not. I “think” it will do the job I need it to, but if it were something that I had some very fine tolerances that I was trying to meet, this one would not be the one I’d want. Everything is just too loose for me and no way to tighten it down. Its just very cheaply made. Will give it a go tomorrow.
