Working on this little project here. It is the mostly printed CNC machine project from thingiverse.
Basically it let's you use 25mm tubing, 3D printed parts, and some hardware store stuff to make a CNC machine.
People have demonstrated them machining aluminum, wood, with lasers, and as a 3D printer.
It may be a little low on the torque side however, but we shall see. I have a few 70oz stepper motors to put in it and try.
The creator of the design sells a kit of the printed parts and mechanical/electronics for $500. All u gotta add in is your own conduit pipe.
This also is my 501st post, and passed 150k views on the blog for a year and a half in operation.
Not too shabby considering only a couple blogs send traffic my way.
