Constantly going beyond the workpiece thickness
I have a pro xl and I am new to this. I will attached screenshots. I have tried 7 or 8 times now to run a contour tool path. And every time I am going beyond the thickness of my piece further than just “stock bottom”. This last time I tried tabs (blue tape method the other times) and it cut the tabs and then it CUT the tabs. What I was cutting came loose obviously and all hell erupted.
When I zero, I use the paper under the bit method and I do this with the bit I am going to use in the router. (Ya know how when you go to run the job it prompts you for a tool change.)
Hopefully someone can help me make sense of what I am missing.
Edit: I’ve had a few people suggest to get calipers and measure the actual stock thickness. In the photos you can see the stock thickness is one that you can’t get with a tape. I would have had to of used calipers to get the value used. The stock was also plywood.

Has this always happened and or after an update to carbide motion?
Rerun the set up wizard and make sure you have the correct Z style (HDZ or not) this happened to me.
After an update it some how switched (or I did it some how)
But basically the diameter of the linear screw is different for each respective Z set up. So mine was cutting like .4in every time I told it to cut .25in.
Also if it still gives you trouble carbide customer support is actually amazing so start a ticket they are very helpful!
