I've been scrounging pieces and parts for a couple of months. Now, I'm getting ready to think about, maybe starting to attempt some sort of construction. My goal is a 3 axis machine to carve foam or soft wood with a Dremal or Roto-zip.
Do I sound like a skeptical pessimist. Maybe, I just have a million things going around in my head that I see as potential problems. Most I've dismissed and I'll try not to ask a bunch of dumb questions on the rest. I am not a machinists nor a computer experts by no means. So, if I can pull this off, anyone can. About 80% of the stuff on this site is way over my head, I hope I don't have to know it all.
Anyway, here is some old medical equipment I picked up. It has 3 axis and they will all end up on top of the machine. So, Flip it over in your head. The first picture is as I found it and the 2nd is after the extras were stripped off. Then a shot of the Steppers that came with it and a close up of the x and y screws. My first questions: Are those screws going to be too steep a thread for the machine? I've been looking for some acme thread to replace them with. Sorry about all the background junk in the pictures, except for my son, he's not junk.
