At that point you can tell the CNC that the current location is Z-0 = current location - thickness of paper used. By sliding this back and forth along the surface of your stock material while lowering the Z axis very slowly, you could teach yourself to feel when the tip of your end mill would start to pinch the paper to the stock ever so slightly. Historically, CNC operators would use a thin piece of paper or a feeler gauge. ![]() Obtaining the stock thickness is easy enough, you just use a caliper or similar measuring device to get a measurement, but the Z-0 point can be tricky. Having trouble visualizing? Take a look at this image: By knowing this point as accurately as possible, as well as the exact thickness of your stock material, you are able to fully define your workspace. ![]() When you are running any project on your CNC, it is vital for a successful outcome that you carefully define the point at which Z=0.įor most projects, Z-0 is the location on the Z axis of your CNC where the tip of your end mill is flush, or just touching the surface of your stock material. ![]()
