Pocket depth setting and tool length changing?

Hello Forum,

 

I am new to Fusion360 and working with a new Tormach 1100PCNC. Double whammy. I have done CNC before.

 

I am trying to practice using 360 by cutting a 2.5" Diameter closed pocket .5" deep in a piece of 3/4" MDF with a 1/4" diameter HSS end mill that has .623 long flutes. I have created the pocket in my drawing and assigned a cutting tool (1/4" end mill with my set parameters) but what I am not sure about (and have not found it in the tutorials) is how the CAM knows what depth to cut the pocket (feature)? I know about the Heights tab but it is unclear as to whether I have to set the depth of the pocket or doesd Fushion know how deep to cut the pocket because I selected the bottom of the pocket?

 

So when I run the program, the mill goes deeper than I want it to in the sample material. I have Z referenced my tool according to the PCNC manual. Any thoughts or suggestions so I can narrow my problem down to ether CAM error or CNC mill set up error (all are my doing).

 

Thanks.
