Robochair,

What tolernaces (in aluminum) are you achieving with your velox setup?
Have you benchmarked your machine for accuracy or repeatability?
i.e. using an indicator , have it return to a reference surface in each of the 3 axis.

Does your CAM or controller allow you to map your lead screw to enhance accuracy? If so, how many points will it allow?
Did you have to adjust scale in any of the 3 axis after you set up the machine?
One or 2 lead screws to move the gantry (low axis) ?
Do the anti backlash nut assemblies require maintenance or periodic adjustment?
Also, which model and size Velox did you buy for $6k?
