I purchased a seashell relief file and imported into vcarve desktop and used it to create a sign. Looks great in vcarve, but my problems is the finish pass. I did a rough pass with 1/4" endmill which seemed to work well, then I did a finish pass with a 1/8" ballnose. The finish pass did not cut any material. The machine moved as it should but the bit never touched the material. I reset the z and tried again, same results.
I am new at this and sure I did something wrong, but I am not sure what it is. Any help is greatly appreciated.
