Head moves x before starting

I am wondering why my head has started to move slightly to the right before starting the job so all objects are moved that far from the left edge. I have the start position set to current position and the origin at bottom left. However, I’m starting with the head position around 50x and 310y, yet it moves over to around 58x before starting. As a result, the final etching is moved away from the desired position. What setting(s) need to be adjusted?
