Thank you so much! It worked perfectly after leaving the WCS as the top plane of the part. I'm used to switching the WCS to different places for different features if we're rotating the part in the vise on the mill. A few more questions: I'm still playing with ways to import files (surfaces vs. solids). Currently I like surfaces because they let me selected closed chains in one click that are on the c-plane. With solids, I have to choose each branch (even though there is only one that is in the c-plane, a c-plane selection is enabled...). For everything else, I prefer solids. How can I select a closed chain in one click on a surface? Our rotary table's speed is very, very slow, due to some incorrect installation. The gcode I've generated now has moves to A0 at every tool change. Currently, I've just been going through by hand and removing these, but is there a way to disable them?

Currently I'm stuck with the job of CNC programmer for the month. I'm using MasterCAM X4, which has been really great. I'm pretty proficient at the basic stuff, but I'm trying to work with the 4th axis. Currently, I'm trying to make a hexagonal shaft from round stock and put some features in the flats. I want the thing to make the part flat, put the features in, rotate 60 degrees, and repeat. To be clear, I'm not trying to make MasterCAM figure out how much it needs to rotate and when, I want to be able to specify the planes for it to cut on, and it will just rotate the 4th axis to get there. My friend said I could just put each feature on a different plane and use that plane as the c-plane and t-plane for that toolpath, and it would automatically rotate 60 degrees to get to the next plane. The g-code output doesn't have these indexing moves. He suspects that it is either the post processor not supporting rotary positioning, or that the post processor is not detecting the change in the c-plane so it doesn't know to rotate the 4th axis. The post processor is aware there is a 4th axis, as it commands it to go to zero during the program, but only once. I don't want to have the 4th axis rotary surfacing toolpath where I need a ball endmill and it does something like a contour surface toolpath, I want it to rotate the part to the correct c-plane for each toolpath. I'm looking for normal 3 axis toolpaths with indexing moves in between. Thanks!
