I agree

As long as the bed has no twist or misalignment then all is well.
I have my lathes set so that the coolant drains to one end effectively.

It may not be absolutely necessary, but a lathe can seem straight but be twisted and I think I've used some of those ones. Runs a taper when there was no reason for it and I was always polishing it out. I think it helps overall accuracy, and eliminates a potential problem. And my friend has a machine level and all it cost me was a beer

I will pose a question re machine levelling

On a long machine and the ones that do not have a bed persay only a pad to set up the carage and tail stock ,levelling is not possible in the normal way , because the said machine including steam turbines for power generation sit on a big ball , so if the ends are level then the middle Is high?

So we're is the level here .

The old way before lasers was to use a wire but this still left the middle high ?

Just a bit of thinking out loud so to speak
