Thanks.

It will be a Rockcliff based variant.

I've baulked at the prices folks want for steel rod & bushings to build it...so I'm going back to the skip!

The old 3 dot matrix printers I've stripped have provided me with steppers, limit switches & one rod each (with two bushings). The steel rod is only 320mm long (& 12mm diameter)...so I'll likely make a CNC that's 300mm-ish in the X & Y axis.

I've convinced myself that the shorter axis, will help with rigidity & therefore accuracy.

My problem is that I'm probably not going to be able to lay my hands on another 3 dot matrix printers for a few months yet...so, there's not a whole lot I can do right now.

Since, I'll be altering the dimension in all 3 axis, I won't be buying the plans, but I can get the gist just by looking at the many photos that abound on the web.
