I’ve got a Fadal VMC 40, using a calmotion usb, and fusion 360:

So x and y axis all run true to the cam programming. However the z axis alway cuts too deep/runs into the part to aggressively to get there. I have done tool setting and fixture setting 100x and don’t know what I’m doing wrong. It tends to cut in nearly 1/2” too deep every time. This machine is new to me, and I am new to machining. I feel like I’ve been through every manual and website trying to find what I’m missing and can’t find it. Any suggestions?

Are you setting the Z zero in the same place both in Fusion and the part? I normally Z set to the top of the part. Sometimes Fusion can be a little tricky to setup properly, you have to make sure it did what you expected. Simulation is your friend.
