It can also be defined as a curve traced by a point where the distance from a given point remains constant as the point moves. More specifically, it is a set of all points in a plane that are equidistant from a given point, called the center. By using metric measurements and seeing what the number of steps per MM the stepper motors are you can calculate how far one step is in metric. Under the covers any inch measurements are converted to metric so if you are comfortable with metric then use that. Two Large Circle Patterns on One Page (5 Diameter) (click on image to download) Medium Circle Stencils. There is a finite numbers of steps of the stepper motors and they will not move a fraction of a step only full steps. The belt calibration is changing the gbrl settings for more or less steps per MM. For the belt lets say you sized exactly 3" but the circle and CC reports a 3" circle but when you cut the circle it is 2.95" or 3.05" then it might be the calibration. If you want to measure the actual size of a small object in inches or centimeters and you don’t have a real ruler at hand, this virtual on-screen online ruler will help you. Please set your diagonal monitor size (in inches): Not sure what your monitor size is Related. If it is the physical size of the circles it might be the belt stretch calibration. A circle of radius 3.25 or diameter 6.5 or circumference 20.42 inches has an area of: 2.14064 × 10 -8 square kilometers (km²) 0.0214064 square meters (m²) 214.064 square centimeters (cm²) 21406.4 square millimeters (mm²) 8.26506 × 10 -9 square miles (mi²) 0. So if your error is in CC it is likely the rounding error. So you could just be hitting the rounding errors for the steps. If needed, substitute 3.14: r 3/ ft 0.96 ft. Inject the circumference into the equation: r (6 ft) / (2 × ) 3/ ft. Recall the formula for the radius of a circle from circumference: r c / (2 × ). The second is the belt stretch calibration needed on most belt CNC machines. To find the radius whose circumference is equal to 6 feet, we follow the steps below: Write the circumference as c 6 ft.
