I am getting my controller ready for my new machine. I am using the GRBL post processor as recommended. When I do the post process, I have 3 options for safe retracts: G28, G53, and clearance height. I am starting my WCS in bottom left corner with z0 being the bottom of the stock. All of these will move and would drive the endmill through the stock to go to the first point of operation. Z remains at zero. I can fix it by adding code at the beginning to raise the z before it moves, but would prefer to not have to do. Is there anything I can change to fix this?

G53 post process is moving z to 4.537" up before moving in X and Y. I dont know if i will have that much travel.
