Chili pepper work space

Is there a way to make the cutting area larger? I have a ox CNC running tinyg, the only comparable controller I have been successful with is chilipeppr. My Ox has the cutting capabilities of 1500x1000. Is there a way in Chilipeppr to change the size
Of the work area? It looks like the area I can work in is about 1000x1000mm.

Do you mean the grid size?
