@macinyash, yes do that if you want the X=0 Y=0 position to be at one corner of the bed, but use negative values where appropriate. For example, if your printer has a X min endstop that triggers when the nozzle is 10mm off the edge of the bed, put -10 in the X minimum field. See https://duet3d.dozuki.com/Wiki/Centering_the_bed_or_setting_the_bed_origin. The values you select in the configurator are put in the M208 commands that it generates.
