The long promised pictures of our homebuilt tool: a xyz table. Built from the pictures from this site: http://homepage.ntlworld.com/gloomy-place/cnc.htm
Basic incredients: some wood, three M8 threaded rods, some M8 nuts, six ball-bearing type drawer-rails.
Stephen built this machine totally by himself, however its not quite simple to get it so it'll be exact. Also note that the wood was hand-sawed, no power tools. Only a standard drill for the wholes and screws.
The Z-axis (vertical) had been removed in this pic to allow us to use it as a drill press for PCBs. Thats why there are some rubber bands are holding the Z-axis up.
Currently we are testing this machine with steppers for X and Y movements. Biggest problem is torque from the steppers we use (gutted from old floppy drives). But it works. You can't even see with the bare eye whewn the table moves if you do single full steps.
The drill holder from underneath.
How the threaded rods are held in place. Biggest problem here is friction. Of course a bearing would be better, but it would cost way more.
