HELP WITH HEIGHT PROBLEM 2D ADAPTIVE CLEARING

[AZZ61170]

HELLO, 

So I've done a new setup under manufacturing set my xyz set my stock and model and wanted to clear away the top waste material using multiple depths of 2.5mm so it should start at the top of the job incrementing down by said value until it reaches the bottom face which is z-11mm but it's doing it vice versa it plunges to z-11 then works up from there but obviously this wont work as it will just plow into solid material and damage the machine , any suggestions  

please see attached screen shots

Hi @AZZ61170,

With in the 2D adaptive passes tab you should see settings for max rough step down. Is this the what you are setting to 2.5mm?
