Minor change to allow more work space during the nozzle change, thanks to @laskr1999 requesting the change #3889
In our opinion it makes still sense to move the extruder in the middle of the x-axis.

Removing Y10 makes sense as well to me. The machine first homes with 'G28 W` => Y=0 at that moment => heat bed has been moved far back allowing for easier access to the nozzle and preventing accidental damage to the bed/sheet in case something fell onto it while changing the nozzle.
