Changing Bed size

[Loumazz (Lou)]

Hi All… Very newbie user here. Have a 3018 Pro CNC with 5W laser. I am able to set up laser and connect to MacBook Pro no problem. controls work the x-axis no problem. I am also able to basically navigate the user interface and design…

Problem is, whenever I try to run a test on a piece of wood, the laser begins the design waaaaaay off the bed? I dont know how to change the bed size… Help? its 12 inches by 7.2 inch bed size…

Thanks
Lou
