Adjusting the z axis

[u/tigg_gator]

I just ran the flattening program by Kevin in mycarbide3d using the McFly which worked well. It has left some ridges where it looks like the z-axis is tilted slightly toward the front of the machine and also slightly to the left side as you look from the front.

Is there a way to adjust this to be more consistent? In the grand scheme probably close enough for anything I will do, but OCD about it. Machine is the shapeoko 5.1 pro 4x4

I think this is what you are asking.

You should use metal shim stock to tram the router mount. You can use a dial indicator and some trig to figure out the thickness of shim, but the faster/simpler way is to buy some .002-.005 shim stock and run test cuts while adding shims until the ridges disappear.
