I did a surfacing run for the first time on my 4 Xxl. I got a series of very small steps moving upward on the y axis as it approaches the front of the machine. The steps are consistent and measure about .3mm. My measuring may be off, it is a hard thing to measure accurately. My read on it is that my y axis slopes up toward the front of the machine. Any advice on what the problem is and how to fix it?
As I think about it a bit more it could be that the router is not square in the y direction. That could make each pass cut a bit deeper forward than it does at the back of the bit.
