I'm forever trying to come up with ideas for cheap parts, I can source these quite cheaply....



I was thinking certainly for the Z axis it should be ok (obviously removing the handle/arm & also stripping the rods & support from the base), but what about two for the X axis & two for the Y axis?

I seek a cheap desktop CNC with a movement of about 12" in the X & Y axis.

I guess it depends on how much 'play' they have (can't say - not seen one in the flesh), but I could possibly negate this by use of a custom arm with a roller skate bearing on it to press up against the rail.
