Is this amount of racking acceptable in my Trident (LDO) 300 cube?

Here's the only corner I can't zero.
Is this too much racking?

It depends. That much movement is acceptable to me. But the real question is why can't you zero it out? Did you tighten belts uneven?

If it were me, I'd try to chase that down. It will probably print fine but knowing it was there would bug me until I resolved it.

I suppose it must be so. If I zero that corner, then the front corner on the same side becomes unzero'd to a similar amount.
If I then tighten the front corner (left), then the right front corner becomes similarly unzero'd.
