What did you do to avoid the warning? And is it the "medium" tool I'm suppose to use? BTW, thanks a lot for your help

I've attached the file. And after try several different stock clearance, the warning still appear each time I try to Regenerate all dirty operations.

Hello everyone, I am new to Mastercam and still learning it. Recently when I doing practise there is a step call us to make rough Step over .05’’ in rough turn (Picture 1) But I haven't find anything called "rough Step" in the lathe rough properties. I wonder if it means Depth of cut (Picture 2). If not, what is it? Besides, when it comes to the groove step, there also comes several problems (picture 3). 1. Depth .05'', but I haven't find "Depth" in groove properties. 2. We are suppose to use a medium tool. However, It seems not fit...(picture 4 & 5) 3.A warning appear, but after I ignore it, nothing happened. (picture 6) Thanks for everyone helping! LATHEP3.MCX-7
