Could you also post the [bed_mesh] section of printer.cfg?

If you know your deviation, I assume you have a bed probe, right? Are you using your bed mesh? Can you share your start GCode?

Rounded corners like this makes me think that you have Klipper’s Resonance Compensation feature overtuned, but you’d have to really be trying to get it this bad. What printer and firmware are you using?

Looks like this may be a known issue for some users.

A couple dozen devices maybe. I don’t really need dedicated ranges, but it’s nice to know exactly which device I’m looking at just by the IP when reading logs.

I know they exist and vaguely what they do, but I don’t know how to set them up. What’s their advantage over simple DHCP reservations for a small client list?

I like the range for new devices- hadn’t thought of that!
