Hello, Not sure how you level your beds on the K1 Max bed I use Trammel spacers made out of tpu that fit on the screw mounts for the heater bed, allowing me to have all 4 corner control of how flat the bed is before the configuration starts.

I tried using spacers on the tripoint mounts for the bed but that was far too fiddly, using the TPU spacers, I got my bed with minimal effort within good alignment and with a little more patience or fit some trammel wheels, I think I could get it pretty close even though my bed seems to dimpled into the middle it is a lot better than it was before and does not seem to wander off after a few prints as well.

There are various articles you can find and read on trammelling your bed with standard vanilla klipper or if it has been rooted using a .CFG file. Here is one I read earlier which gives a nice explanation of both.

Back to fine tuning my bed.
