So I got my machine built and did the paper hello world test with success.
I set up a simple file with 6 parts designed in illustrator and CAMed in Carbide Create. Basic 1/4in endmill doing an outside cut through material with tabs. When it executed, it did one pass around the first part, and then somehow the entire file/drawing shifted down about an inch. the second pass proceeded to overlap the first, and 2 of the parts were hanging off the bottom of my stock as a result of the shift.
I tried re-cutting the 3 bad parts and the same thing happened. Any help would be much appreciated!!
