This is usually a slicer setting and not a firmware problem. What slicer are you using?
From your axis limits I assume that you have set them so that X0 Y0 is at one corner of the bed, and the other corner is X220 Y220. To print at the centre you need to tell your slicer what the bed dimensions are and/or tell it that the centre is at X110 Y110.
Alternatively you can set the axis limits so that X0 Y0 is the beds centre, and configure that in your slicer too. See https://duet3d.dozuki.com/Wiki/Centering_the_bed_or_setting_the_bed_origin.
Thank you, im using Cura 4.4!
This are my settings for my printer, and normaly it should be okay (i think)
When in the homed position is the nozzle off the edge of the bed? If so you can use a negative value for the M208 minima to indicate how far off the bed edge the nozzle is when homed. That will help keep the slicer and firmware bed centers synced up.
Thank you guys, i couldn't find any option under Cura to set the center at X110 Y110.
I set the axis limits to M208 X-25 Y20 Z0 S1 and it seems to be centered now.

Sounds like you have it working... but... if you ever wish Cura to generate G-Code that assumes 0,0 is at the center of the bed:
Again, don't do this unless you also change the printer to match...
