In this video, GCodeTutor is back with a step-by-step tutorial on programming a boring operation with G-Code. There are a few things that can catch us out when boring. The main confusion for people new to g-code programming is calculating the points on a chamfer. Marc explains how he approaches a 45-degree edge braking chamfer and how to plot the points with the X axis moving double the distance as the Z axis to achieve the correct angle. | Practical Machinist
