I have done several 3D projects without major issues. However, I am stuck and hoping someone can help. I have a 20" w x 20" w x 4" stock. I used the McFly to get it down to the 3.5" working height needed before the 3D roughing pass. Everything went well on the facing pathing and then did a tool change to the #201 for the 3D roughing, everything went well for the 3D roughing. However, after the prompt for the bit change #122 for the 3D finishing the machine went to the correct X/Y axis and buried itself to the bottom of the Z and tried to move the right, causing damage to the part obviously and also slightly moving the part (thank goodness for good work holding, but it still moved.) I had to hit the emergency stop and reset the machine. So, my question is, after the crash, how can I re-zero and ensure the finishing path will perform as intended? Total depth of the 3D addition is 2.5" on a 1" base.
If you use a boundary that is offset more than the radius of the finish cutter, the path will dive to the bottom of the stock. Simulate the path & make sure it’s not diving.
Add a base to the model to keep the tool up off the table.

It’s not showing on the simulation or the tool pathing that it is diving to the bottom of the base, at least from what I see.
I created different vectors for the facing and rough/finishing paths. The facing one was oversized to catch the entire stock, but the 3D rough and finish was set to the exact dimension.
