Does anyone know if it is possible to have the cnc move to a specific location after a tool change and "automatically" zero it's self in the z direction?  I have an Acension control box. Can this be modified in the z zero routine?  We use a z zero plate now.
Thanks for your help

My screenset has a macro that does it. You need two z zero plates. One fixed, for tool changes, and one movable, for the initial zero. There's a video here showing it working.
