Thanks Brian,
yes, I was aware there is screw mapping, but I'm curious to know if there is anything for compensating inaccurate guideways. When you look at the dimensions of Chads 5 axis router any error in the mounting of the linear rails (and unless you can precision grind the full area of the mounting faces there will be some error) will be multiplied over the length of the beams in question. Also, as the z axis moves closer to the middle of the y axis, the y axis will tend to sag and twist due to gravity, this could in theory have a compensation model which adjusts the axies accordingly to minimise the effect. Is there currently any way of doing this or is there plans in the pipeline?
