rough-help

[Tarkus]

Good day to all,
I am doing some practice with the various hypermill functions, but I find myself with a workmanship that gives me problems:
I can't make a roughing of a fairly trivial piece, or better, I can't make the workmanship down to the bottom of the piece, (see image) what I can do with the constant z finish.
I'm sure I'm wrong, but what?
I attach an image and .step and .e3 files for those who want to take a look at it.
Thank you in advance.

try to visit this page, there is an online hypermill course that you might need.

apart from the dated post, I do not see any difficulties in roughing up to the base of the piece. but to give an answer and a solution I should see each processing board.
