I have all 0.00 in the x,y,and z axis on computer when trying to configure xxl on computer. I also do not get the shapeoko settings drop down when I click on settings. Any help would be greatly appreciated.
If you click “Load Defaults” near the dimensions boxes, you should get a pop-up window where you can select your machine type, this will then correctly populate the X/Y/Z dimensions, see:
What is the z axis type for the xxl? Leadscrew one makes the z axis reverse
That depends on how old it is. Do you have the belt driven z axis?
