An hour or so was spent tweaking the column with aluminum shims and dial test indicator to get to a level of accuracy I am after (I'm more realistic now...).
I'll go into a little bit more as the pics are presented.
First order of the day is to reduce the play between the Z axis saddle and the column dovetails. A new piece of A2Z super gib was used. Play was considerably reduced, at least visually. The knocking sound I once experienced when I brought the column back from Mike was gone.
The tramming of this part was done using the 2 set screws holding the A2Z spacer block. Clever idea from the folks at A2Z.
The bottom of the spacer was shimmed to level the 2 indicators' reading. A little more tricky than the column.
The Pendant from VistaCNC is really fun to use. There are more function available than I need. Good to have around the mill.
Blessing to all!
