I am using an ender 3 w/ SKR v2 mini. With the stock firmware, home is off the lower left corner of the bed rather than dead center in the bed. I like this configuration more as the head does not drip filament on to the middle of the bed while preheating. Apparently, setting these values resolves this issue based up on the research I did, but they can only be set at build time for the firmware.
Let me know if this is the info you need or if there are any other questions I can answer.
