It's an Anilam 1100M conversion and the Z connection is a bit on the
weak side.

Hi Gene,
The Z axis ball screw attachment is a bit weak and is not very
consistent. It attaches to the quill with a 1/4" screw and another one
a bit bigger. And the X ways have a bit of wear so the saddle dips a
bit in the middle.

Ahh, I was geting my exercise by jumping to the conclusion you were
referring to the knee drive.
Wouldn't be the first time. :)
As for the quill drive, I think I'd make a clamp collar to grab the
bottom 1/4" of the cylinder of the quill, and plant the ball screws
bottom in that. I'd have to see & feel the table ways though. I'd assume
you've tweaked the x gibs already. It could be slack in the y gibs
allowing the table to go off balance, pivoting up on one edge or the
other of the y saddle on the knee. That could mimic wear in the center
of the x table. I'd sure put a dial on it and do some wrestling.
Sometimes what you feel, and what the dial tells you are different
things.
OTOH, I am probably carrying coal to Newcastle since I've no experience
with a bridgeport.

I wish the BP knee mill Z was good enough to 3D print I'd give it a
try... I just need to get on with making the CoreXY printer.

Whats the problem with it John?
