V-Minion Bed Mesh question
So I’m curious as to what a “good variance” would be for a machine of this size. I’ve been at it for a while today and the best I can get is a .091 mm variance. This is down from .455mm. Is it safe to stop here or should I keep on trying to improve it?

That's absolutely fine, <0.2mm Variance is usually your goal, but with the Minion <0.1mm is easily achieved so that's my personal goal
Perfect thanks!
and with that low number you don't need a lot of bed mesh points 🙂
What exactly did you do to correct your variance? That's an impressive reduction. Mine bounces between .5mm and .4mm depending on moon phase.

I would like to second that question @shades1138 ! How did you bring it down so well?
So I started with new nylon washers and got the bed finger tight.
Then I took a level to it and made sure the bed was level then I leveled the x gantry to the bed and ran a mesh
Based off that mesh I tightened to screws to adjust and redid the mesh and then adjusted again <- did this about 12x until it was at the .09 number stated above
Also made sure to heat the hotend to 150 before each mesh
Not going to lie it took a while to get there
oh.. it's a 200mm bed... Never mind... 
Why’s that?
I am dealing with a 500mm bed. I think the 200mm are just better from the factory.
