I've decided to start building my own small (20"x20") cnc mill. I've been doing alot of research and feel I have a pretty good grasp of what is needed.
I found 3 stepper motors for $25 on ebay, but I'm not sure if they're strong enough (for wood and some plastic). There is no torque rating listed. They are older Vexta ph265m-33. 24V DC 0.21 amps per phase (2-phase). 0.9 degrees per step. I'm planning on using either 3/8" acme or 1/2" acme lead screws.
