Resurrecting this old thread as I found it EXTREMELY helpful as I am working on spindle/column alignment.
I have added the screw jacks to adjust X and those work great.
What I am having an issue with is the Y axis and shims.
I started off with the Y kicked out toward user by a good bit, around 0.008". So I added about a 0.003" shim at the top between head and head carrier. This reduced the nod in the Y direction to about 0.003" toward user. So I added another smaller shim. I thought if I over did it, it would nod away from user.
Well, it somehow defied logic and is kicked out even worse toward user at 0.010"!
Of course this whole time X value improved down to 0.00025"!
Any thoughts on tackling this Y nod issue?
Unfortunately, I dont see an easy way to do adjustments without shims. Fabricating jacks for the Y value would be tough because it would have to be on center and the motor is in the way for that.
