Just a few pics of my machine.
I used the Oatley electronics stepper motor drives K142B and K142C together, these drives work so well,they have lots of grunt at higher speeds.
The motors I used are 4V and only 42mm squ. but still have more than enough power to drive the machine.
The leadscrews are 1/4WW allthread with 200 step motors that makes the resolution 4000 per inch and I run at 40 Ipm.
The basic structure of the machine was made with off-cuts of various aluminium extrusions and some recycled linear bearings from some old photo processing equipment".
All of that wiring looks a little excessive but this is because the machine was built with 4 opto switches for each axis, 2 limit and 2 home switches.
The strange looking things on the side are recycled switch-mode power supplies.
I also built the rotary axis shown in these pictures, it's great.
I unplug the "Y" axis and plug it into the rotary axis to engrave pens, rings and bracelets etc.

Thanks Stan.
The new machine (router) is bigger and better but not yet finnished.
I use the Oatley constant current source kits, the voltage varies depending on the current required at any one time from a few volts to 34V at full speed.
