Used standard settings in Luban with Firmware 1.8.0 and Snapmaker PLA filament.
Spend a lot of time manually leveling the bed. I realized using a straight edge that the bed was falling off on the edges. Don’t have a large enough lapping plate to sand down the bed flat so I used small washers on the outside to raise the bed (floating) and used the inner most 4 screws to suck down the bed until it was level (enough) before using the calibration routine…
Came out nice…
