Thanks for taking the time to think about this.
And i have to agree, but it binds in the middle and the z axis Pipe is parallel down to the +/- 0.5 mm (smallest i can messure).
I think the z axis bearing carriers are a little out of alingment, as the z axiz as a "bit" of movement when you try and twist it. Beause the Z axis (like you said) has the least amount of travel, i suppose this could be binding.
I will pull down the z axis and check the alignment of the bearing carriers against the center line. and then check pipes against the centerline of the Yaxis carrier. but as these are dead parallel it will only be off to one side of the other.
The only other thing i could be is that he bearing block in the z axis is not square. As i did this with hand tools that would not surprise me.
If this is the case i will use the baring block as the center line and run the carriers at 90 degrees to it.
