I wanted to mill something today and noticed that the contours are totally skewed. A short time later I saw how the cnc module was moving in the quick-change system and was about to fall out.
Looks like you’ve got the quick swap thing on the wrong way. I just got mine today and the instructions show the module should drop down vertically into place. That way there’s no way it could slide sideways.
Edit: Looks like I don’t know what I’m talking about
